imagine that there exists people like this that gives you an honest respectable in depth video of something that you can actually learn from, i have a hard time learning things but i only had to watch this once
Thank you so much, seems when people start talking forced induction they throw a bunch of side-remarks in there and complicated everything they're saying to show off their words. From a guy with no turbo experience whatsoever, I appreciated this video very much and it pointed me in the direction I was looking for.
Very cool cars! I had several Datsun Z cars growing up. I always wanted to turbo them, but never had the time or money back then. Now Im working on a blow through system for my Studebaker 289 V8.. Stude was the pioneer of boost.
Although I drive an 86 z28, I still love watching informative stuff on cars, such as boosting. Awesome video, I'm not a forced induction expert, but I learned alot.
Bryan Dunn Lots of potential in the Camaro series. Lots of budget twin turbo kits available for the Small block Chevy engines. Superchargers are great in the Camaro as well.
Budget Boosting Agreed, I can pickup the piping, fmic, wastegate and bov, and a decent (non-ebay) turbo for a little over a grand. My problem would be tuning, my car uses the TPI setup from gm, so its run off of an ecm with a pretuned memcal. I think my next project is going to be a mkiii supra, although I haven't decided whether or not I like the 7m-gte platform more than the 1jz.
DUDE...I had a 77 280z and would have gave my left nut to have that set up. This was the best most simple, straight forward DIY how to on a budget even. Never know you could turbo a carbed motor. And compared to an EFI upgrade + turbo's it's a real budget build with big power potential. While retaining drivability.
starbattles1 Yes, I remember when I decided to go that route due to the stock fuel injection not handling the turbo set up very well. I went the blow through turbo route and I have liked that set up the best. I started with the Demon 650 blow through carb which was pretty good and eventually to the Quick fuel SS-650-BAN 4 barrel carburetor and I like it even more. I have the intake and exhaust manifolds off this Z car waiting for a custom twin turbo header which a friend of mine fabricated to fit two of my z cars which will fit any z from 1970-1983, all the L series inline sixes. It was fabricated to fit in these cars once the air conditioning compressor is removed and a few other things that are in the way for the twin turbo setup. To me no A/C is a small price to pay for a twin T04e powered L28 Z car. Once I get this new twin turbo header, I will get with my fabricator and he will start making them so we can sell them to others desiring twin turbo z cars. We will sell them on our budgetboosting ebay account where we currently sell our window stickers.
All Out Throttle awesome, boosted Mustangs fun to run. They are very popular at NMCA races in all classes. Would like to race that series in the future.
Huh, I have a 280zx with an L28 EFI. I thought that you HAD to go Megasquirt, big injectors, T3 and whatnot. But this looks very interesting.... I’ve never seen a carbureted car that is also turbocharged. Thank you for introducing this route to me. I’m considering this now that I see it.
The carburetor is designed for boost blow thru. It is a quick fuel 650-BAN www.summitracing.com/parts/QFT-Q650-BAN. This carburetor with an arizona Z 4 bbl intake manifold will allow boost thru carb without complicated fuel injection systems. arizonazcar.com/engine
Thanks a lot a light bulb went off in my head when you mentioned the T connection for the oil supply. I just realized that engine oil is under pressure from the oil pump so all you have to do is tap into that pressurized oil and it will be pushed into the turbo... I used to be confused as to how turbos got fed with oil O thought maybe the turbo has a pump inside that pulls oil from the oil pan or there's gravity feeding but none of those sound like they would work.
Terry Lewis Nice, lots of aftermarket support for fox body mustangs and many have been successfully turbocharged to very monstrous proportions. I really like the foxbody and its potential. Thank you for watching. I made 4 new videos and two of them are related to turbo conversions.
Your in with this here,and thanks for a brief explanation of how the thing works I've studied little about the systems but always held interest in the older cars run with much electronic assist.
arthur clark Yes the older cars really benefit from turbocharging. I see many old monstrous twin turbo Camaros, Corvettes, Mustangs and many others blow through the traps and very high speeds and very low times at Top Gun Raceway.
back pressure is not considered from the point of bottom dead center but again the boast adds pressure the cylinder should test positive for vacuum if valve timing is correct likely in most of the older cars it's not as tight or correctly timed when it is the turbo is likely larger than normal
arthur clark At idle a turbo engine will see its normal vacuum, as load is added to the engine and boost increases, vacuum will become positive pressure so having the stock vacuum advance will not benefit the older vehicles. I removed the vacuum from my electronic distributor so it is a constant and no adjustment on vacuum. I also install a boost referenced fuel pressure regulator that ensures fuel pressure rises as boost rises. When much larger turbochargers are installed, usable boost will take longer to build up and directly reflect negative vacuum and boost pressures. One way valves or breathers should be installed to ensure boost does not pressurize the valve covers or engine block. Lots of things to consider when turbocharging a non-turbo car. Its quite the adventure though.
I thought I had a Z problem lol. keep it up, good to see another blowthrough z running around. my blowthrough setup is using triple side drafts, but this is what i was planing to do had i not found all the parts. great video!
Budget Boosting I believe I found your website with the old HKS triple deuce blow through turbo kit. I have always liked that kit ever since I saw it in Japan on an S130z with twin TD06 turbochargers on a 3.1 stroker. That car was wicked and that kit is severely hard to find. In the states Jim Cook Racing used to sell the Cartech triple weber side draft complete kit including a T04 turbocharger, external wastegates, intercooler and all the tubing and bolt ups necessary for installation for around $3500. If only those complete kits were still for sale, that company would make a fortune since there are many old Z enthusiests than there were then..... I like the HKS set up you installed, since you were running rich, a much larger turbocharger would fix that, somewhere around a T70 with ball bearing, 15-20 lbs of boost, 100 octane fuel and you would be golden.
Austin Hermann Outstanding, do make sure you have the great assortment of gages to monitor all the engine perimeters that will change when adding boost to an already strong engine.
I have been referring to this video for years, thinking about various vehicles I've had over the years that had carbs on them. But I'm doing it finally. Putting a turbo on an old 85 dodge ramcharger with the 318. I'm hoping to get it done before a big trip to moab Utah next April
@@ChinzySpecials uhh......😅 not so good. The weather got bad so I had to stop working on it for like 2 months. We got thw motor and trans in, and got the motor fired up for thw first time without the turbos, and then went to move it undernits own power for the first time, but something is wrong with the trans, so it has to come back out
@@garymaddux2000 haha I get that completely I'm doing a single turbo on a sbc. Got the turbo next is blow through carb and all the rest of the parts. Turbo kit will be made of pure exhaust tubing haha
@@ChinzySpecials I still need to get my turbo and blow through carb. Or I might go with an efi setup to make it simpler. For now, my headers just come up and point forward at where the radiator use to be lol.
@@garymaddux2000 haha I still have to gap the rings haha got the turbo engine all apart in my shop haha. The truck is under a snowbank lol. But I'm just throwing pretty much using every paycheck for parts haha. Easy to do when you are 18 lol. But let's of projects as it it
I’m building a 91 Isuzu 2.3 turbo. Trying to find a decent manifold that’s not 700.00. Geminiturbo had a nice manifold and other than stock all I can find. Thanks for the info. Hopefully by mid summer I’ll be boosted!
You could have an adapter flange made with a T3 turbo flange and a custom made bolt on adapter for your intake manifold to run a holley style blow through carb.
What if the turbo used for 110cc carburetor bike? how the placement like? Is it from turbo to carburetor and then to the engine, or from carburetor to turbo then to the engine?
Nice job on the blow thru setup!! I had a 79 280zx I converted to turbo but kept the EFI and it was a pain to get enough fuel to the engine at higher boost levels so I ended up using hobbs switches and extra injectors to feed it enough. Detonation was always a problem until I replaced the distributer and ecu with ones from a turbo car, then I used water injection at higher boost levels to prevent detonation. Now I got an 86 4x4 Nissan pickup with a 2.4 liter 4 banger and I'm planning a blow thru setup using a t3/t4 hybred turbo and intercooler fed into a Holley 350 2 barrel that's been prepped internally for turbo use with a boost referenced power valve and pitot tube on the bowl vent to keep a positive pressure in the bowl along with an EFI fuel pump and aeromotive boost sensing regulator. I have all the parts gathered up and ready now but need to get a smaller power brake booster since the turbo won't fit in there with the stock booster.
SuperDaveZilla I also first tried the fuel injection on my 79 and the fuel delivery had issues and that is what led to my using the blow through setup. I even ran the MAF sensor in the boost path just prior to the intake manifold so the MAF directly adjusted to boost but even that was not enough fuel delivery for boost and the low octane pump gas. Found that the blow through set up works well and will even work with the pump gas as long as the boost is not too high. Thank you for watching and look forward to some pictures of the Nissan 4x4 truck blow through when its done.
There is spring in blow off valve what you can usually adjust tighter and it isn't open with low boost if is it adjust hard. you can hear tsuhhh sound when it's open and there isn't thad sound.
Mmm perfect for my project I have 1987 mazda b2000 truck but is a carburetor I never thought u can boosted time to work on it if I have any questions hope you can give me some ideas or information thanks
would you have to advance your ignition as well? would you not only have to change the idle ignition timing but also how fast it changes and the WOT ignition timing? how would you know how much to do it? and how would you go about it? by modifying the distributor? i have a bmw m10b18 not whatever this car is by the way
Budget Boosting what are these devices called? the ones to control timing, are they sort of like an FMU but for timing? my main problem at the moment is i live in europe and the only blow through carbs i can find are from america, expensive and then i have to have them shipped on top and maybe pay tax, and as they dont even sell them here i cant see it being easy to find one second hand. i might have to give up on this which is a shame as a boosted, carbed 4 cylinder would be fairly rare thing to see, and really cheap to buy replacement engines for and such. might just have to engine swap to something with fuel injection and do that :( sounds so boring compared to boosting a m10, would be like my own version of a 2002 xD other option is to try megasquirt the carbed engine, but for that money i could just buy a fuel injected one. i suppose i gotta choose easy, cheap and boring. or hard, expensive and epic xD
+Charlie Ward would be real neat if you could find a used 335i engine, they are well over 300 hp 300 lb torque twin turbo straight six from the factory on your lighter BMW would be a monster.
Budget Boosting that would be perfect but and engine like that would cost a fortune where I live, I've probably bought a m40 and I'm going to just put a turbo and bigger injectors, not very special all I can afford tho thanks for your help :)
Sorry I'm late to the party, but you can use a standard carb in two ways. Firstly isn't so easy (unless it's fairly commonly done with that model of carb for example SU carbs), seal up any vents/throttle shafts etc and find a way of venting the float bowl as well as being able to pressurise it on boost. *Second & much easier* but less tidy maybe is if you build the whole carb into a plenum chamber. This means the whole carb inside and out sees boost and thus no excess pressure is put on it. You then only need to seal up the point the throttle cable and fuel line enter, just make sure to use a linear fuel pressure regulator with the plenum set up so that your fuel pressure stays at the correct level relative to the boost rather than the boost overcoming the fuel pressure causing the car to lean out.
How the hell are you going to say building a boost box for a carb is easier than $50 worth of mods that anyone can do in a day to any Holley carb easier ? To the original poster if you haven't already bought a blow through there's a right up by hanger18. Not everything listed is necessary unless your making 18psi plus. I have built 3 Holley blow through carbs for around $50 each. But the most mine have seen is 15psi.
sun4u2day I have not worked on the Opel GT before but a basic turbo system will work on any engine as long as the basics are covered. A turbo flange welded or bolted on the end of the exhaust manifold, or custom pipe to put the turbocharger where it will fit in the engine compartment well. Find the oil pressure switch and install a custom oil supply and return line kit on the turbocharger. Find a good place between the exhaust manifold before the turbo flange to install external wastegate unless you have a turbocharger with an internal wastegate already on it. Purchase and install universal intercooler with intercooler tubing kit to route all your boost hoses. Decide on and purchase which blow through carburetor you would like to use. Route the boost hose to it after it passes through the intercooler to where it seals tight to the blow through carburetor intake so boost pressure will not blow any of the hoses out under pressure, must be strong connections. Connect an intake to the compressor inlet of turbo charger. Install boost controller if you desire higher boost levels than what the wastegate puts out already. Down pipe from the turbo discharge to the exhaust system of car. Also watch all of my other turbo videos, they show a lot of the boost hose routing and show where I put parts in the engine bay. In the future I will get everything needed for a custom installation and make a video on making a non turbo charged car turbocharged car and show every thing. I hope that covered your questions. Thank you for watching and commenting.
Like the idea... how much boost do run? I own 71 240z with l28et on megasquirt... the cost of your Demon carburetor was about the cost of megasquirt standalone.
Do you need an intercooler? I read some suggesting it will run better without since the fuel will mix better with air at higher temp and the boost isn't high enough that temp will be a problem.
All those Datsuns .. I have a couple . My brother has one with 350 , lowered ,nitrous , flares , anyway thanks for showing the turbo , I want to put one on my c10
I forgot where your other video regarding the fuel pressure regulator, but i'm going to post this here. In your fuel pressure regulator video you said you had one for boost, yet they also make one for vacuum. So, in my vehicle which runs a carb but not any boost, would it be practical to put a vacuum controlled fuel pressure regulator to keep my carburetor with fuel?
i was wondering if you could help me out? I am building a carbureted 5.3 with a single turbo. I was wondering what would be a good fuel pump and regulator for that setup. Any help would be great thanks
Aeromotive red or black fuel pump is great, bosch makes great boost referenced fuel pressure regulators, Aeromotive does too. Many great ones out there.
You'd probably get better performance to relocate the air filter to the grille area, its gotta be oullin in hot air in that spot. That bein said, im new to this style set up so thank you for the information!
how are you controling how much boost your making. I'm trying to turbo a Chevy s10 with a built 4.3 I'd like to run about 10psi on the street and 15psi at the track. do you use a manual valve in the system? if so where?
the boost is controlled by the wastegate which bypasses exhaust spinning the turbocharger when it reaches boost pressure that compresses spring inside wastegate. A controller can be connected to the wastegate to raise the boost higher than the spring's compression rate.
May seem like a stupid question but how can you get an accurate oil pressure reading if it is setup up like you have it ?. Oil pressure sensors have pressured oil directly feeding to it and only it. Giving it another place to pass by it i don't see how it can get the right reading. For example say before you put that tee there it reads 40 psi or lbs of oil pressure, now with that pressured oil having a second passage off that same feed it now can only read say 20 psi or lbs due to there being a second feed which causes the oil to for lack of a better word bypass the sending unit. Am i mistaken or am i correct ? ...
IrnMaiden304 First off, I believe no such thing as stupid question. When it comes to performance always ask questions because a lot of performance or lack of is at stake. About oil pressure, The way the T fitting is straight off the block oil supply and the pressure sender is right on the T, then the turbo oil supply, once the engine starts and idles around several seconds, oil pressure will stabilize and be very accurate. The only way oil pressure will not be correct is if there is a leak on your turbo oil supply line, return line or any other major oil leak on the engine. That can reduce oil pressure readings. Once oil is circulating in the engine, takes some seconds after starting, you will see stable oil pressure and accurate despite turbo oil lines. People do the oil filter relocation kits and oil cooler kits too, which takes a few seconds to get accurate oil pressure after starting. It takes the oil pump a bit to get all the air and run oil through all the oil passages until stable oil pressure is reached. Hope this answers your question.
Blowoff* valves aren't necessary, but bypass valves in general, yes, ALWAYS run one on a boosted gasoline setup. Important tip: a blowoff valve is a specific type of bypass valve. I know stock tuning sometimes won't compensate quite correctly for a true blowoff valve [versus a stock bypass valve], but running a full on blowoff valve is undeniably safer than having no bypass at all. When the throttle plate closes under boost, if there's no bypass valve, that pressurized air has nowhere to go but back out through the turbocharger, in the wrong direction. Even if it doesn't literally cause the turbo to momentarily spin backwards, it can still mechanically stress the turbo unnecessarily. Overall good video though. Always run some sort of bypass valve on your turbocharged gasoline engine.
what is ur opinion on in closing the carb in a box for installing a turbo. plan on putting a 4.9 i6 in my 97 expedition n putting a turbo on it. not wanting much more than 5 lbs or so of boost. just want enuff power to pull a load
+Budget Boosting I remember seeing the people with the old import mini trucks running them. I just need enough to push a 4.9 ford i6 up to 250 hp n 300 ft lb torque.
+sketchyssk8shop You should have no problem, the torque and power on the inline six is great once it has enough carburetor. From the factory, many of those sixes were under carbureted with a very small 1 bbl. The larger 4 bbl. carb with some boost should meet your goals.
i keep getting told i need a fuel pressure regulator in a blow through setup. is this true ? The way you explain it with confidence make me believe they are wrong.
Yes, boost referenced fuel pressure regulator is best to raise 1 psi fuel pressure to 1 psi boost. I made a different video elaborating more about that. Many things to turbocharging a video, it takes quite a few videos to share everything.
Bobby John Timing adjustments, mine is at 18 degrees btdc, 100 octane avgas fuel which prevents most detonation, boost reference fuel pressure regulator that rises fuel pressure with the boost. Colder spark plugs, stock is a 6 heat range I run 7 and sometimes 8 heat range which is colder. A real effective intercooler also helps combat detonation as well. Every one of these steps helps prevent detonation.
look I want you to help me with this I have this car and I want to do this blow through way on engine polonez model 96 with normal carburetor and there's option to make fuel go more then regular to engine
So you don't suggest running a BOV? So you don't mind blowing your turbo to bits when you let off? You don't mind the dangerous situation of 'boost surge' where you let off and it doesn't immediately respond?
***** I take care of my turbochargers, monitor EGT, fuel pressure, boost pressure, regular oil changes with synthetic oils. No problem with any of my turbochargers. Most of my turbo cars do not have blow off valves, the blue 280zx custom turbo in the video you are commenting in DOES have a BOV.
Budget Boosting I'm referring to when you said that you don't need a BOV. The problem isn't immediate, but you'll ruin the turbo by breaking the one way bearing for the turbine which can shatter the casing, all cause because the pressure that was compressed by the turbo then won't all go into the cylinder, some will try to exit back out where it came in, that is why a BOV was designed and is implemented in every car that features a turbocharger. Then there's the boost surge when you let off the throttle because of the still compressed air, some goes back out the intake and some still goes into the cylinder which on a FI engine it will run lean.
***** Really depends on the size and type of the turbocharger. I usually do not run them and turbochargers are designed to be strong but they must be taken care of. Including idling down around 5 minutes before shutdown to ensure clean cooler oil is going through them. So many variables can cause a failed turbo. I have not seen lack of a blow off valve being the problem. It was caused by some other forms of turbocharger care neglect.
Couple questions. WHat boost is the carb capable of handling? As much as large jets allow? How much boost have you got it to so far? I will be doing this on a 351 Cleveland. Any thoughts or suggestions?
starbattles1 I was running around 18 pounds of boost. It should support 21 pounds just fine and jetting and other factors such as fuel octane and timing also will help increase or limit boost ranges. I am considering turbocharging my 1989 F250 4x4 with the 351 Winsor V-8 in the future when my other cars get done....
thats a one super great video i've learnt alot from it iam about to fit a turbo to my 1600 engine i got a turbo kit installing it by now i need to ask about 1- how to adjust the AFR and how do i manage it correctly 2- how to set up my carburetor for the turbo charger 3- where to install the BOV before the inter cooler as u did or after it or it doesnt matter anyway? and once again thx for the great video
Ahmed Nabil You can install your blow off valve anywhere on turbo compressor discharge or as I did. The important part is you pick a good place where it fits well. Fuel air mixture can be done by the carburetor jetting process and by way of a boost referenced fuel pressure regulator, I made videos on both those subjects you can watch.
Budget Boosting yea i did watched all of the videos related to the questions i've asked i recently made the oil connection ( connector and a return to the oil pan ) tomorrow i will fit the turbo compressor to the manifold as for the AFR i will get a gauge to measure the lean and rich process and start jetting it until it get the suitable ratio i got the fuel jets as the following as a standard factory 115 for 1st gate which is primary and 125 for the secondary throttle .. i replaced the secondary with 135 jet is there anything else i can do to my carburetor ? and thx for replying ^_^
It would work great. They sell TBI kits with MAP sensors that can track boost and make adjustments to fuel on the fly up to 21psi. They are a bit expensive but worth it in the long run. Summit Racing has several to choose from which have a Holley 4 barrel bolt pattern.
i put a 50mm turbo on my 300 inline 6, when i get to 4th and 5 th gear and floor it, starts to studder and the engine kinda cuts out and loses power, is that because of my injectors are too small?
timing could be wrong, boost could be too high for the amount of fuel available to the injectors. Many factors. Usually when it cuts out, it usually indicates not enough fuel pressure or available for boost.
Hi guys. I've got a datsun 120y. Was hoping to turbo whilst keeping the carby as I've never seen this done before. Money and time is not an issue for me. Just information. Any chance you guys could help me?
2013 you had lots of Datsun Z cars around. In this video, was this an 8.3 low compression motor converted to boost. Or a flat top piston motor ? You don't see blow thu much then or now in 2020. Great info....thank you
Fuck the old cars just a sec tho lol get a brand new car get a new old carbed engine swap it out and chuck this system on it and confuse every person my age or younger

Budget Boosting I believe I found your website with the old HKS triple deuce blow through turbo kit. I have always liked that kit ever since I saw it in Japan on an S130z with twin TD06 turbochargers on a 3.1 stroker. That car was wicked and that kit is severely hard to find. In the states Jim Cook Racing used to sell the Cartech triple weber side draft complete kit including a T04 turbocharger, external wastegates, intercooler and all the tubing and bolt ups necessary for installation for around $3500. If only those complete kits were still for sale, that company would make a fortune since there are many old Z enthusiests than there were then..... I like the HKS set up you installed, since you were running rich, a much larger turbocharger would fix that, somewhere around a T70 with ball bearing, 15-20 lbs of boost, 100 octane fuel and you would be golden.
It’s the exact engine I’m looking to turbo awesome vid
plan on doing this to my 521 stroker in my truck cant wait to see the results gonna be a damn monster
Austin Hermann Outstanding, do make sure you have the great assortment of gages to monitor all the engine perimeters that will change when adding boost to an already strong engine.
Going to boost my Carb’d 4AC Toyota Corolla thanks to you
This video was awesome thank you for posting 🙏
I have been referring to this video for years, thinking about various vehicles I've had over the years that had carbs on them. But I'm doing it finally. Putting a turbo on an old 85 dodge ramcharger with the 318. I'm hoping to get it done before a big trip to moab Utah next April
How is your project coming along?
@@ChinzySpecials uhh......😅 not so good. The weather got bad so I had to stop working on it for like 2 months. We got thw motor and trans in, and got the motor fired up for thw first time without the turbos, and then went to move it undernits own power for the first time, but something is wrong with the trans, so it has to come back out
@@garymaddux2000 haha I get that completely I'm doing a single turbo on a sbc. Got the turbo next is blow through carb and all the rest of the parts. Turbo kit will be made of pure exhaust tubing haha
@@ChinzySpecials I still need to get my turbo and blow through carb. Or I might go with an efi setup to make it simpler. For now, my headers just come up and point forward at where the radiator use to be lol.
@@garymaddux2000 haha I still have to gap the rings haha got the turbo engine all apart in my shop haha. The truck is under a snowbank lol. But I'm just throwing pretty much using every paycheck for parts haha. Easy to do when you are 18 lol. But let's of projects as it it
I’m building a 91 Isuzu 2.3 turbo. Trying to find a decent manifold that’s not 700.00. Geminiturbo had a nice manifold and other than stock all I can find. Thanks for the info. Hopefully by mid summer I’ll be boosted!
You could have an adapter flange made with a T3 turbo flange and a custom made bolt on adapter for your intake manifold to run a holley style blow through carb.
you my friend have gotten a subscriber. hope you still do more videos
Really well explained.
Awesome vid
What if the turbo used for 110cc carburetor bike? how the placement like? Is it from turbo to carburetor and then to the engine, or from carburetor to turbo then to the engine?
Do you need a boost reference for fuel pressure with that carb? What's a good starting point for fuel pressure for it? Thanks!
you just got yourself a new sub...love your shit..
Ghosty wun Thank you for the comments and thank you for watching. Happy boosting !
Nice job on the blow thru setup!! I had a 79 280zx I converted to turbo but kept the EFI and it was a pain to get enough fuel to the engine at higher boost levels so I ended up using hobbs switches and extra injectors to feed it enough. Detonation was always a problem until I replaced the distributer and ecu with ones from a turbo car, then I used water injection at higher boost levels to prevent detonation. Now I got an 86 4x4 Nissan pickup with a 2.4 liter 4 banger and I'm planning a blow thru setup using a t3/t4 hybred turbo and intercooler fed into a Holley 350 2 barrel that's been prepped internally for turbo use with a boost referenced power valve and pitot tube on the bowl vent to keep a positive pressure in the bowl along with an EFI fuel pump and aeromotive boost sensing regulator. I have all the parts gathered up and ready now but need to get a smaller power brake booster since the turbo won't fit in there with the stock booster.
SuperDaveZilla I also first tried the fuel injection on my 79 and the fuel delivery had issues and that is what led to my using the blow through setup. I even ran the MAF sensor in the boost path just prior to the intake manifold so the MAF directly adjusted to boost but even that was not enough fuel delivery for boost and the low octane pump gas. Found that the blow through set up works well and will even work with the pump gas as long as the boost is not too high. Thank you for watching and look forward to some pictures of the Nissan 4x4 truck blow through when its done.
No cane!!! Good job man awesome progress!!!
Its an older video
+Budget Boosting do you have a video with a carburetor enclosure
the blow through carburetor video has a 4 barrel carburetor enclosure. It is not a large enclosure but designed for blow through application.
I need help ! I got a 4G33 engine in my car (4 cylinder inline gasoline) with carb, can i turbocharge it?
Great video! I'm looking at buying an Lseries motor to rebuild and potentially use, which ones are the ones to have? TIA
very helpful and educational good stuff
There is spring in blow off valve what you can usually adjust tighter and it isn't open with low boost if is it adjust hard. you can hear tsuhhh sound when it's open and there isn't thad sound.
johanijohani yes the ones that have the adjustable spring are the best type.
Great video and alot of useful information 👍
You've cleared a lot of things up for me!!
is the blow off valve responsible for the flutter sound?
I like this video coz its simple, easy to understand and gave all da info i needed!! Good work guys! U have a subscriber now!!!
Outstanding, thank you, it is our goal to share what we have learned and see others accomplish this great technique on their fun cars.
thanks for those videos man , im learning alot from them :D
This video Literally just save me like $700 thank you
No worries man, good to hear the video's are having real world applications to people.
Yeah great video.. Guy is a great teacher.. should be working at ITT Tech!
KFLY67 Thank you, I had instructing and facilitating experience teaching my fellow military personnel during various times in my 21 year career.
Great video, enjoyed and very informative
nica8487 Thank you for your comments and watching, glad you like them. We will continue.
The cardboard gauge holder is a nice touch! Did you paint it blue or did the cardboard come that way?
I have a holly street demon 650 cfm will that work
Great job. I wish you were my neighbor. Does this type of system cause problems in this car?
Move on over man the more the merrier
perfect perfect video bro , perfectly explained 💪💥🤘🏍️
Mmm perfect for my project I have 1987 mazda b2000 truck but is a carburetor I never thought u can boosted time to work on it if I have any questions hope you can give me some ideas or information thanks
Was it a l28 turbo before the blow through carb or if not what internals are you running
Im gonna use this idea on my bobber, be fun to try
would you have to advance your ignition as well? would you not only have to change the idle ignition timing but also how fast it changes and the WOT ignition timing? how would you know how much to do it? and how would you go about it? by modifying the distributor? i have a bmw m10b18 not whatever this car is by the way
Budget Boosting what are these devices called? the ones to control timing, are they sort of like an FMU but for timing? my main problem at the moment is i live in europe and the only blow through carbs i can find are from america, expensive and then i have to have them shipped on top and maybe pay tax, and as they dont even sell them here i cant see it being easy to find one second hand. i might have to give up on this which is a shame as a boosted, carbed 4 cylinder would be fairly rare thing to see, and really cheap to buy replacement engines for and such. might just have to engine swap to something with fuel injection and do that :( sounds so boring compared to boosting a m10, would be like my own version of a 2002 xD other option is to try megasquirt the carbed engine, but for that money i could just buy a fuel injected one. i suppose i gotta choose easy, cheap and boring. or hard, expensive and epic xD
+Charlie Ward would be real neat if you could find a used 335i engine, they are well over 300 hp 300 lb torque twin turbo straight six from the factory on your lighter BMW would be a monster.
Budget Boosting that would be perfect but and engine like that would cost a fortune where I live, I've probably bought a m40 and I'm going to just put a turbo and bigger injectors, not very special all I can afford tho thanks for your help :)
Freaking fantastic you talk everything love it!
I love the sound of those Z’s
Thanks man your video was very helpful. I'm about to attempt this on a 86 Monte Carlo with a stock HO 305. Gonna order a twin turbo kit from eBay.
Kevin Williams That should be a beast, Summit sells great Quick fuel blow through SS-650-BAN carb.
Awesome. Thanks
@@KevinWilliams-px6il it will be an awesome grenade.take lots of video when you run it/blow it up
wish i had found you guys earlier !
Hello sir can i use a standard N/A carb in conjunction with a turbo? i can see you are using a well made turbo carb. thanks.
Sorry I'm late to the party, but you can use a standard carb in two ways. Firstly isn't so easy (unless it's fairly commonly done with that model of carb for example SU carbs), seal up any vents/throttle shafts etc and find a way of venting the float bowl as well as being able to pressurise it on boost. *Second & much easier* but less tidy maybe is if you build the whole carb into a plenum chamber. This means the whole carb inside and out sees boost and thus no excess pressure is put on it. You then only need to seal up the point the throttle cable and fuel line enter, just make sure to use a linear fuel pressure regulator with the plenum set up so that your fuel pressure stays at the correct level relative to the boost rather than the boost overcoming the fuel pressure causing the car to lean out.
How the hell are you going to say building a boost box for a carb is easier than $50 worth of mods that anyone can do in a day to any Holley carb easier ? To the original poster if you haven't already bought a blow through there's a right up by hanger18. Not everything listed is necessary unless your making 18psi plus. I have built 3 Holley blow through carbs for around $50 each. But the most mine have seen is 15psi.
no
would like to know more as i have a 71 opel gtwhat i have too do with exhaust and intake make them out of pipe any help appreciated
sun4u2day I have not worked on the Opel GT before but a basic turbo system will work on any engine as long as the basics are covered. A turbo flange welded or bolted on the end of the exhaust manifold, or custom pipe to put the turbocharger where it will fit in the engine compartment well. Find the oil pressure switch and install a custom oil supply and return line kit on the turbocharger. Find a good place between the exhaust manifold before the turbo flange to install external wastegate unless you have a turbocharger with an internal wastegate already on it. Purchase and install universal intercooler with intercooler tubing kit to route all your boost hoses. Decide on and purchase which blow through carburetor you would like to use. Route the boost hose to it after it passes through the intercooler to where it seals tight to the blow through carburetor intake so boost pressure will not blow any of the hoses out under pressure, must be strong connections. Connect an intake to the compressor inlet of turbo charger. Install boost controller if you desire higher boost levels than what the wastegate puts out already. Down pipe from the turbo discharge to the exhaust system of car. Also watch all of my other turbo videos, they show a lot of the boost hose routing and show where I put parts in the engine bay. In the future I will get everything needed for a custom installation and make a video on making a non turbo charged car turbocharged car and show every thing. I hope that covered your questions. Thank you for watching and commenting.
I almost jizzed in my pants when I saw all the z's. I miss mine alot. Thanks for info, the z's were an added bonus.
Bryant Arnold Thank you, Its great to have people that appreciate our work.
Like the idea... how much boost do run? I own 71 240z with l28et on megasquirt... the cost of your Demon carburetor was about the cost of megasquirt standalone.
Do you need an intercooler? I read some suggesting it will run better without since the fuel will mix better with air at higher temp and the boost isn't high enough that temp will be a problem.
All those Datsuns .. I have a couple . My brother has one with 350 , lowered ,nitrous , flares , anyway thanks for showing the turbo , I want to put one on my c10
I forgot where your other video regarding the fuel pressure regulator, but i'm going to post this here. In your fuel pressure regulator video you said you had one for boost, yet they also make one for vacuum. So, in my vehicle which runs a carb but not any boost, would it be practical to put a vacuum controlled fuel pressure regulator to keep my carburetor with fuel?
This car is awesome, Safety wire and zip ties make anything possible.
What would be a good size carb for a Toyota 22r for a blow through set up?
i was wondering if you could help me out? I am building a carbureted 5.3 with a single turbo. I was wondering what would be a good fuel pump and regulator for that setup. Any help would be great thanks
Aeromotive red or black fuel pump is great, bosch makes great boost referenced fuel pressure regulators, Aeromotive does too. Many great ones out there.
You'd probably get better performance to relocate the air filter to the grille area, its gotta be oullin in hot air in that spot. That bein said, im new to this style set up so thank you for the information!
how are you controling how much boost your making. I'm trying to turbo a Chevy s10 with a built 4.3 I'd like to run about 10psi on the street and 15psi at the track. do you use a manual valve in the system? if so where?
wastegate spring and blow off valve perhaps?
the boost is controlled by the wastegate which bypasses exhaust spinning the turbocharger when it reaches boost pressure that compresses spring inside wastegate. A controller can be connected to the wastegate to raise the boost higher than the spring's compression rate.
May seem like a stupid question but how can you get an accurate oil pressure reading if it is setup up like you have it ?. Oil pressure sensors have pressured oil directly feeding to it and only it. Giving it another place to pass by it i don't see how it can get the right reading. For example say before you put that tee there it reads 40 psi or lbs of oil pressure, now with that pressured oil having a second passage off that same feed it now can only read say 20 psi or lbs due to there being a second feed which causes the oil to for lack of a better word bypass the sending unit. Am i mistaken or am i correct ? ...
IrnMaiden304 First off, I believe no such thing as stupid question. When it comes to performance always ask questions because a lot of performance or lack of is at stake. About oil pressure, The way the T fitting is straight off the block oil supply and the pressure sender is right on the T, then the turbo oil supply, once the engine starts and idles around several seconds, oil pressure will stabilize and be very accurate. The only way oil pressure will not be correct is if there is a leak on your turbo oil supply line, return line or any other major oil leak on the engine. That can reduce oil pressure readings. Once oil is circulating in the engine, takes some seconds after starting, you will see stable oil pressure and accurate despite turbo oil lines. People do the oil filter relocation kits and oil cooler kits too, which takes a few seconds to get accurate oil pressure after starting. It takes the oil pump a bit to get all the air and run oil through all the oil passages until stable oil pressure is reached. Hope this answers your question.
Makes sense since it is a closed system. Ty
IrnMaiden304 I have a new video on oil supply and return for turbocharger installation.
Blowoff* valves aren't necessary, but bypass valves in general, yes, ALWAYS run one on a boosted gasoline setup. Important tip: a blowoff valve is a specific type of bypass valve. I know stock tuning sometimes won't compensate quite correctly for a true blowoff valve [versus a stock bypass valve], but running a full on blowoff valve is undeniably safer than having no bypass at all. When the throttle plate closes under boost, if there's no bypass valve, that pressurized air has nowhere to go but back out through the turbocharger, in the wrong direction. Even if it doesn't literally cause the turbo to momentarily spin backwards, it can still mechanically stress the turbo unnecessarily. Overall good video though. Always run some sort of bypass valve on your turbocharged gasoline engine.
what is ur opinion on in closing the carb in a box for installing a turbo. plan on putting a 4.9 i6 in my 97 expedition n putting a turbo on it. not wanting much more than 5 lbs or so of boost. just want enuff power to pull a load
+sketchyssk8shop that should work fine for low boost.
+Budget Boosting I remember seeing the people with the old import mini trucks running them. I just need enough to push a 4.9 ford i6 up to 250 hp n 300 ft lb torque.
+sketchyssk8shop You should have no problem, the torque and power on the inline six is great once it has enough carburetor. From the factory, many of those sixes were under carbureted with a very small 1 bbl. The larger 4 bbl. carb with some boost should meet your goals.
Awesome 👍 Thanks. Always wondered.
i keep getting told i need a fuel pressure regulator in a blow through setup. is this true ? The way you explain it with confidence make me believe they are wrong.
Yes, boost referenced fuel pressure regulator is best to raise 1 psi fuel pressure to 1 psi boost. I made a different video elaborating more about that. Many things to turbocharging a video, it takes quite a few videos to share everything.
Budget Boosting Fuel Pressure Regulator-required.....and a lot more to know. Got it.
great video, rare one indeed
Holy crap. This is amazing.
Most adjust the boost referenced power valve circuit...for fuel enrichment
How do you prevent detonation?? Use a secondary electric pump for boost? Thanks
Bobby John Timing adjustments, mine is at 18 degrees btdc, 100 octane avgas fuel which prevents most detonation, boost reference fuel pressure regulator that rises fuel pressure with the boost. Colder spark plugs, stock is a 6 heat range I run 7 and sometimes 8 heat range which is colder. A real effective intercooler also helps combat detonation as well. Every one of these steps helps prevent detonation.
I would like to ask about is that save fuel or it will take more then normal ?
+Mohamed Borhan That carburetor is quite large so the fuel economy on this set up is not great. This setup is primarily for performance.
look I want you to help me with this I have this car and I want to do this blow through way on engine polonez model 96 with normal carburetor and there's option to make fuel go more then regular to engine
So you don't suggest running a BOV? So you don't mind blowing your turbo to bits when you let off? You don't mind the dangerous situation of 'boost surge' where you let off and it doesn't immediately respond?
***** I take care of my turbochargers, monitor EGT, fuel pressure, boost pressure, regular oil changes with synthetic oils. No problem with any of my turbochargers. Most of my turbo cars do not have blow off valves, the blue 280zx custom turbo in the video you are commenting in DOES have a BOV.
Budget Boosting I'm referring to when you said that you don't need a BOV. The problem isn't immediate, but you'll ruin the turbo by breaking the one way bearing for the turbine which can shatter the casing, all cause because the pressure that was compressed by the turbo then won't all go into the cylinder, some will try to exit back out where it came in, that is why a BOV was designed and is implemented in every car that features a turbocharger. Then there's the boost surge when you let off the throttle because of the still compressed air, some goes back out the intake and some still goes into the cylinder which on a FI engine it will run lean.
***** Really depends on the size and type of the turbocharger. I usually do not run them and turbochargers are designed to be strong but they must be taken care of. Including idling down around 5 minutes before shutdown to ensure clean cooler oil is going through them. So many variables can cause a failed turbo. I have not seen lack of a blow off valve being the problem. It was caused by some other forms of turbocharger care neglect.
Dude, you are awesome, thanks!
I'm looking for a blowthrough carb that will work on my 1.5l tercel, any advise?
Couple questions. WHat boost is the carb capable of handling? As much as large jets allow? How much boost have you got it to so far?
I will be doing this on a 351 Cleveland. Any thoughts or suggestions?
starbattles1 I was running around 18 pounds of boost. It should support 21 pounds just fine and jetting and other factors such as fuel octane and timing also will help increase or limit boost ranges. I am considering turbocharging my 1989 F250 4x4 with the 351 Winsor V-8 in the future when my other cars get done....
thats a one super great video i've learnt alot from it
iam about to fit a turbo to my 1600 engine i got a turbo kit installing it by now
i need to ask about
1- how to adjust the AFR and how do i manage it correctly
2- how to set up my carburetor for the turbo charger
3- where to install the BOV before the inter cooler as u did or after it or it doesnt matter anyway?
and once again thx for the great video
Ahmed Nabil You can install your blow off valve anywhere on turbo compressor discharge or as I did. The important part is you pick a good place where it fits well. Fuel air mixture can be done by the carburetor jetting process and by way of a boost referenced fuel pressure regulator, I made videos on both those subjects you can watch.
Budget Boosting yea i did watched all of the videos related to the questions i've asked
i recently made the oil connection ( connector and a return to the oil pan )
tomorrow i will fit the turbo compressor to the manifold
as for the AFR i will get a gauge to measure the lean and rich process and start jetting it until it get the suitable ratio
i got the fuel jets as the following as a standard factory 115 for 1st gate which is primary and 125 for the secondary throttle .. i replaced the secondary with 135 jet
is there anything else i can do to my carburetor ?
and thx for replying ^_^
any idea on how this would work with a throttle body
It would work great. They sell TBI kits with MAP sensors that can track boost and make adjustments to fuel on the fly up to 21psi. They are a bit expensive but worth it in the long run. Summit Racing has several to choose from which have a Holley 4 barrel bolt pattern.
differently
Holy shit I'm so godamn jealous, the 240-80z are my favorite cars, mainly the 240z
you need to do a video on timming and the advance for blow thru and draw thru as one needs to be locked ;)
i put a 50mm turbo on my 300 inline 6, when i get to 4th and 5 th gear and floor it, starts to studder and the engine kinda cuts out and loses power, is that because of my injectors are too small?
timing could be wrong, boost could be too high for the amount of fuel available to the injectors. Many factors. Usually when it cuts out, it usually indicates not enough fuel pressure or available for boost.
im using the stock efi, stock injectors, stock fuel pump, and stock map sensor.
stock may not be able to handle what your throwing at it
i think ill put in a bigger fuel pump and some bigger injectors and see how it runs, later on ill buy an ecu and pin it and try to tune it
a boost referenced fuel pressure regulator will really help you. It raises fuel pressure for every pound of boost.
Hi guys. I've got a datsun 120y. Was hoping to turbo whilst keeping the carby as I've never seen this done before. Money and time is not an issue for me. Just information. Any chance you guys could help me?
2013 you had lots of Datsun Z cars around.
In this video, was this an 8.3 low compression motor converted to boost. Or a flat top piston motor ?
You don't see blow thu much then or now in 2020.
Great info....thank you
Always wondered if I can turbo my 84 Toyota 4Runner 22r carburetor??
Hello. Can install turbo on any carburetor
Where does the air fuel ratio sensor get its info at?
Can you make a video on the Boost Timing master in this car
What intake and turbo exhaust are you using???
Need to know please!!!!
I have a 460 big block, looking to do the same thing.
Zackary Wilson I look forward to seeing the results, it will be quite monstrous.
Fuck the old cars just a sec tho lol get a brand new car get a new old carbed engine swap it out and chuck this system on it and confuse every person my age or younger
