I love how all these videos are so realistic for the average guy. Working outside in the backyard with basic tools oppose to in a shop with hundreds of dollars of air tools and lifts. Keep the videos coming.
Right? I bought NB for $3k and was looking at flying miata kits for $3.4k or ebay kits as low as $1.6k and well shit! That is about how much I paid for my car. I like the whole cheap out where you can, buy GOOD 2nd hand quality parts aspect, and when you can afford it you can easily replace.
I also agree, BUT don't make the mistake of lowering the importance of know-how and very good quality parts. I got an FM kit about 7 years ago, with a GT2554R. Nothing is broken...that turbo now has around 60 THOUSAND miles at 250 hp crank...the reliability is insane...no way you can get that with discount parts.
i bet i coulda bought 16 ebay turbos for my integra for the price of the gt4554r 7 years ago
Yes using any old tools at hand
Ææ0
i watched this like a year ago and it was way above my head i love coming back to old videos like this and having it all make sense to me
Òjjj
Same here. Over the past couple of years I've learnt how to rebuilt a turbo once removed and diagnosed thanks to videos like this. 👍Before there was no way I was doing a job as scary as this but would do it without a second thought now.
I got my GodSpeed Ko4 turbo off of craigslist for 50$s then I got a rebuild off of eBay for 40 something dollars..
it's been almost 2yrs now and no problems at 22psi! but because I just mentioned it, my car is sure to blow up now.
+Audiwan Kenobi Perfect.
TheCarPassionChannel sure is!...minus the exploding car,right?...just checking.
Audiwan Kenobi Hahaha yes, that would not be good.
Did u ballance the turbo?? Or use the methode used in this video?? (Marking)
Love these Miata videos man. I really appreciate the effort and time put into these videos. Totally changed my mind on Miata's. I now want to buy one and boost it as well!!
Great videos man!
I'm in the middle of turbo'ing my 93
sadly I had to set the project aside for winter, Luckily you'll be way ahead of me by spring so I can watch all your videos right before I do my own :) obviously with alot of other research as well
Recently I've been watching your videos religiously in preparation for my own turbo Miata. Hahaha, thanks for the informative videos!
This is probably one of the most useful videos I've ever seen
Love how in depth these are, you never miss a thing.
He missed something
Oh god, my turbo just went out on me and I was freaking out on a rebuild. you don't know how happy I was seeing your channel name on the first video that popped up
Great videos man! Keep doin what you do.
Bro I have watched a lot of your videos and they are so helpful, thank you!!
congratulations on another great video. keep up the good work!☺
Awesome video! I love the fact that you did it outside with basic tools, no fancy shop with air tools. I'll use this video as a guide to try to rebuild my truck's turbos. I have an 07 International 9400i with a Cat C-15, 1.3 million miles, my turbos work but look like they're about to crap themselves any minute. Is there any rust prevention to coat the turbos with?
Very nice video! Keep this good job!
Very step by step. Excellent! ❤️
great videos love them so much, this is helping me be ready for my boosted Miata build :-)
OK thank you very much !! keep those videos coming man!!:)
Miata wars. Episode 5 the Miata strikes back
Awesome video man thank you! Can't wait to do the same
You, Sir, are a real hero!
Nice vid easy to follow good info ! Nice job👍
I have A4 b7, and it's just starting to make a flutter sound on its own, without a whistle or bov!
great video, very in depth. I'm new to this channel so will definitely be subscribing and checking out your other vids
Thanks!
Thank you for your tutorial video its a big help.
Fantastic video
This is a cool video on how to rebuild your turbo, I think I have a T 25 laying around from a SR 20 DET. I think I will try to rebuild it using this video. Thanks !!
Check out my BoostVlogs video on my other channel about removing seized turbine housing bolts, that might help you as well. /watch?v=3B-Yw4syNCE
love the videos bro, cant wait to get back in a na miata so i can boost it :)
LOL! my td04 broke. Just googled turbo rebuild and this came up! I guess i came full circle because you are of the reasons to turbo my mx-5 x)
9:18 Never seen an allen key used like that before, thanks for the tip!
+Chandler Cowser All those years of working at a bicycle shop... :) Cheers
Dude why don't you have more subs? Your videos are fantastic!
Another excellent vid... I will be doing the full timing belt / front seals / waterpump as per your video in a couple of weeks, and during next year make everything stronger and prep the car to turbo later in the year. I'm planning to use a TD04 turbo off an impreza, and want to learn more about wastegate actuators and aftermarket boost controllers....Basically how to set and control your boost (i plan to use a p+p ecu) but want to know how these things can be set physically, and what might work well... Kinda hoping you might be planning on covering this...
Keep up the excellent vids... Cheers, Ollie.
+ollydubhead Hmmm... how the various types of boost controllers work... sounds like a good idea to me.
thanks for give us this video
best explanation videos👍
Hey man what would be the best quality rebuild kit or does it really matter?
Nice Video. Its getting better and better!Btw: Your House could use a little paint😉
+Fuelfoxx We're in the middle of doing some stucco repair!
+TheCarPassionChannel 👍
Thanks for the great video. So I can actually rebuild without taking the trouble to get the turbo rebalanced? I’ll do that trick where you marked a line on it. Nice one.
I noticed you did not mention having the turbo re-balanced. While in theory if you mark the compressor and shaft, and reinstall carefully, it should be balanced, in theory this is not always true. Even if it is misaligned ever so slightly, this can throw the balance off
Subscribed !
9:19 love how you work that alan key ;)
+PVznPie Haha that used to save me a lot of time when I worked in bicycle shops
Did you ever do turbo rebuilds for bicycles? hahaha
PVznPie LOL I can't say that I have.
I'd like some advice, Do you think you could help me? I'll pm you my question.
That turbo housing is clean , compare to the one from my car. Thanks for the video! Can you make a video from a Volvo xc90- D5 - 136 KW, how to rebuild?
quick question : is the disassembling process the same (or similar) for all turbos ?
Good video. My t25 Emusa is smoking bad. Please advise.
Nice vidio. I like it
Beautiful
man you need a tv show !!!
Do you think a turbo off of a r33 would be decent I've heard that some of them blow up cuz of the ceramic turbo blades
isn't this turbo the bell engineering china charger? Would you recommend the bell engineering china charger or the enjuku t25? Keep up the videos Greg
Did you have any issues getting your car smogged in California with the t25 turbo?I was trying to stick with the Greddy TD04H-15G kit since it has the carb sticker.
Awesome video! Purchased a T25 Garrett Turbo today for cheap. One random question I had, how are you deleting the AFM since Broke and Boosted will be using a stock ECU? Just curious, keep up the great vids.
+VTCar.Club I will not be deleting the AFM.
that's easy enough!
Great video!
Just a note though, locktite is made to melt at temperature and therefore will do no good on a turbo.
+Cory Yalowicki You want to make sure to get the high temp stuff which is good for 500 degrees. The compressor side and the CHRA will not exceed that, and you won't use it on the turbine side since it will get waaay hotter than that.
Thank you sir
What do you think about the roller bearing upgrades they offer?
WOOOO FINALLY! bummer about the mic mistake in the middle, but a quality video as always!
+Sam Williams Yeah what happened was I dropped the external recorder at then end of the clip and didn't realize it corrupted the audio file until I was editing the video, so I used the camera audio.
Thats always a bummer. Still a good vid and awesome work. This car will be cool! Are you planning to just daily the B and B, and maybe go for even more power on the other car???
Sam Williams Actually, B&B will be for sale upon finishing. I plan to continue daily use of my main car.
Cool. Well good luck with the rest of the build. whoever gets the car will be a lucky guy!
Would you recommend using a torque wrench or it's not really necessary?
best to undo fan nut with a log extension socket bar and have a socket in vice for the exh side ,,,, so not risk bending shaft .in .the push down method shown ,,,also can fit carbon seal on intake side round alloy thing ,, so you can use with suck thru carburettor.. i have one on suzuki 1100 motorcycle
its awesome to see this build coming together! im getting a miata some time within the next 2 years and definetly plan on turboing on a budget. do you know if a turbo/turbo setup like this would be reliable to dailydrive for a couple years?
+Capt Fuzzy Plays If you're planning on daily driving and having it as your only car, I always recommend starting with Megasquirt. That's the major difference between this build, and the more "proper" way to do it. You'd have a faster, more reliable car if you have the right management.
+TheCarPassionChannel allright cool! any other tips i should know about?
Capt Fuzzy Plays Engine management is the heart of a reliable build really, make sure you have someone setup the safeguards in your ECU if you don't know how to do it, they can save your engine. I bought nearly everything for may car twice because I realized I needed better parts, etc. Go with 750cc injectors, they'll handle anything a stock engine can including E85. I bought 420cc, then realized I wanted more power so I had to upgrade. Bought a clutch that could hold 185wtq, started slipping so I had to upgrade. Bought a $350 china turbo, upgraded to a Garrett because again, I wanted more power. Always go for the better parts, it's worth it in the end!
+TheCarPassionChannel thanks a ton dude!
Hey Greg! Where’d you get your snap ring pliers? I have bought 2 pairs now that are both too small.
Hey man, know this is an old video, but im hoping you can answer a question for me, on the exhaust side it looks like a piece of pipe has been cut and welded to separate the chamber between exhaust and wastegate. Was this to prevent turbulence and pressure build up? Cheers! Really enjoying you videos, they are a great help for my current turbo project!
Yeah, I don't really like the design honestly, I had a lot of cracking issues with the Begi downpipe
hi Craig . awesome video as always buddy!! I was just wondering if you could help me out I have a gt2871r turbo on my car and I need to buy a banjo bolt for my turbo. can you please recommend to me how many millimeters the hole should be on the banjo bolt so the car doesn't smoke from the exhaust? Thank you
Personally I run a 1mm restrictor on my Garrett GT turbos and I've had good luck.
Thanks save a lot of money
is it ok to have a little play of compressor wheel inside
the housing ? or it shouldn’t move at all?
TheCarPassionChannel, Idk if you still read the comments on these old videos, but I’ve got the same t25 from enjuku for my 94 miata. I spent a couple hours today trying to remove the snap ring to clock my compressor housing and I broke both of my snap ring pliers. This thing is so tight even after a bit of wd-40. I also destroyed some skin on my hand when the pliers slipped off and pinched it, so I’m taking a break for a bit haha. What snap ring pliers did you use for this video?
Coady Lewis The snapring is brutal on these turbos... I had to use beefy snapring pliers on mine, and good technique.
I rebuilt 3 turbos now and this is how I do it but the most important part is getting the correct parts cuz I rebuilt 2 with bearings fans and compressor shaft 10k km later no problem but 1 with only new bearing and rings but they were slightly wider and scrashed the housing and leaks way worse than it was
Nice!!!
Hey Greg, only this past week found your channel, great content, love the hands on side of your videos
My question is, the turbo you rebuild in this video, was it the Chinese turbo? I'm considering buying one of the new units from Thailand, or is it a waste of time and stick with genuine?
+Wayne Clement Yes the turbo I rebuilt here is a Chinese turbo, it's the T25/T28 Begi sells (also Enjuku Racing as the "SR20 replacement turbo") for around $350. They seem to be consistently good quality, where the $180 ebay turbos seem to be good sometimes, and other times fall apart. I'd definitely recommend it, although it's not the fastest spooler!
Thanks Greg, do you think one of the better built (Chinese/Thai) units would be more durable in a low boost application (Going by experience with this unit, I know you're gona say you're not an expert!) :D
Wayne Clement Heck, this thing held up for nearly 30,000 miles on 14psi
How do you go about choosing the right turbo manifold? Off the top of my head, I would think that price point, construction, position, application and performance are some of the metrics that one would use when choosing one. What are your thoughts?
The best way is to decide what your main use of the car is going to be. For most builds, a high quality cast manifold is the best option. They're usually around $400, they perform well, and they are BULLETproof. You can go with a tubular manifold for higher performance but they take up more space, are more expensive, and less durable.
I don't even have a miata but I love your videos haha
+austin SOLO Good to hear! A lot of the work and techniques I do in my videos can be applied to other cars and other mechanical things in general. I got a lot of my wrenching skill from working as a bicycle mechanic for 6 years!
+TheCarPassionChannel that definitely helps man! I'd like to get a na miata eventually as as daily while I build my forester haha but I feel like I'm too big for them
Would you recomend buying a turbo apart and assamble it at home?how do i balance it if so
all of these miata videos have made me certian that i want one for my first car
my plan is to get a 1.6 liter and vinyl wrap it a royal blue, raceland coil overs, at fist i want to get a full manzo exhaust system and then go turbo when i can, some sort of a "cold air" intake, 2 inch wheel spacers, and maybe some white plasti dipped diamond steelies or maybe some nice bbs rim but not to sure yet
Just a couple suggestions... IMO, you should get different coil overs because race lands suck lol and instead of the spacer, get wider wheels, it'll make the car look SO mean plus a wider wheels is nicer. And I'm speaking from an owner of a 1993 Miata with 15x8 wheels on
oh ok yea ik race lands are crappy i might go with some thing a little nicer with maybe some camber adjustability
+Dale Jackson I've got a Manzo exhaust on my car, it's a bit loud for daily driving but I don't mind it. For wheels Advanti Storm S1's are gonna be going on mine after I finish piecing together my turbo build. For coilovers though you should consider Flyin Miata. They're a bit pricey but they give the car great feel in the corners.
never seen anyone turn an allen key the way you just did lmao
Awwww yeaahhh! :)
Alright so i know the turbo u have for project broke&boosted is a t25, i want to know what turbo u have on ur other miata? Great video by the way! Thanks in advance.
+FukYoCauch The exact turbo for Broke & Boosted is a Chinese "T25/T28 Hybrid" also known as a "T2854" In my opinion it's not the most ideal T25 sizing for the Miata, but it still works pretty well. The one I have on my other car is a Garrett GT2554R, which is the smallest ball bearing turbo Garrett makes. That, is an amazing turbo, and arguably the BEST version of the T25 for a 1.6L Miata. 1.8L's would be a little better suited with a GT2560R. Being the highest performing T25's you can get, they are also the most expensive at around $1000 new.
I know this is an old post, but I am rebuilding a T25 SR20DET that I found. Three questions. 1. Where did you get it? 2. How long did your rebuild kit last? 3. How did you clean your CHRA?
Mike Mohr eBay, $45 (make sure you get the 360° thrust washer) and it's still going strong after 20,000 miles. I did not clean out the CHRA, didn't see any reason to.
TheCarPassionChannel - kudos to you for interpreting my question correctly! "Where did you get it" could have referred to the turbo, but you correctly deduced that I was referring to the rebuild kit.
That bronze "washer" isn't a washer. It's the Thrust Bearing
Hey! So even though i marked my compressor wheel/nut/shaft together, i’ve managed to lose my markings, what to do now?
Two questions: How do you remove the wheels when the wheels won't come off the shaft? And I noticed you gave no time in the video to inspecting and measuring the shaft for wear. I understand the bushings are a brass alloy and are meant to take the abuse rather than the shaft, but I would think there would still a shaft inspection step. There most certainly are wear marks on your shaft in this vid. Nothing of consequence, I'm sure, but wear nonetheless.
I don't even have a Miata yet and I've been watching this whole series lol. Hopefully will have one within a month though
+Real Talk Sweet!
+TheCarPassionChannel thanks for making these videos, you make everything so clear and easy to follow
Hey Greg , I have a 99 miata and I'm starting the process of piecing a kit together . Do you think a sr20det T25 would be a good turbo for a miata ?
It's basically the best budget turbo you can put on a Miata engine.
What caused the shaft play before rebuild? Were the journal bearings scored/damaged?
+arcticgod619 The inside of the old journal bearings was just worn ever so slightly. The tolerances are so tight, even a fraction of a mm of wear will be noticeable when you check for play.
I paid $150 for a used Garret t25 with no shaft play. Did I do decent, or did I get hosed? Thanks for the vid BTW, I bought the new one because my old one is about to go. Now I can rebuild the old one and have a spare!
+Casey Lockwood Sounds perfect.
Is a turbo rebuild utterly necessary? I know its keeping on the safe side but are the chances high for them to konk out if not rebuilt?
If your compressor wheel is hitting the compressor housing, yes it needs to be rebuilt before it eats itself. If it just has some play but no contact, then it doesn't really need it.
Can you please tell me where I can buy turbo charger kits for Hino 2016 , 268 model ?I need few turbo kits I'm really screwed I can't find it anywhere. Thanks good man
love this turbo rebuild I will need it when I get my t25 soon I also wanted to know as you watched the video the home made ecu from haggard garage but I noticed that when your megasquirt video you didn't have to build it so I wanted to know if you have to build it,I do have time to build it but at the same time I don't want to waste 8 hours building an ecu.
+Adrian Garcia Mine is a PnP so I did not have to build it. It would take some time to build it yourself, but it's probably worth it; $450 instead of $850.
+TheCarPassionChannel that is a really big amount of money I could be saving but I really don't know how to do what he did so might as well get the pnp,also which website did you buy your t25 turbo I checked on ebay but I really don't trust them as I have trust issues with them with all the parts being defective that's what I heard but if you can give me a link for a fairly good priced t25 turbo lt would Very much appreciated thanks also love your content can't stop rewatching your videos.
Adrian Garcia Your best options are either a used Garrett T25 from a forum/craigslist/junkyard for $75-$250, an ebay T25 for $180 or so, the Enjuku T25 for $350, or a new GT25 from Garrett for $1000.
+TheCarPassionChannel I'll be safe and go with enjuku racing
Good video man, unfortunately you forgot to line up the oil seals correctly. 😟
How do you rebuild it to make more boost? Just curious, my turbo is almost through the door and the one that comes with the vw stage 2 kit says they used same housing but its $1800!!!
The only way to make more power from a turbo that's already maxed out is by getting a larger compressor side. And that's assuming the exhaust isn't fully choked already
what's your advice on driving a car with a blown turbo?? I have the chance to get a pretty clean 240 but it has a blown turbo and I can't tow it... car is 10 hours away from me...
It depends what's "blown". If the oil seals are bad you'll be burning a lot of oil
💚💚💚💚 bookmark/ notes : compression wheel 🍦🧁ball of paper / shredder 🚁 …..ect…..tbc…..-g-b, bot
Was broke and boosted solid for what it was? Doing the same setup for now. Just want to know if it's worth it
It was solid, MS made it better but even with MS it's still a budget build really.
Is t25 turbocharger compatible with Detroit Diesel turbo ? Thanks
lol u oiled that shaft like a pro.. ahahahah jk jk
As a professional shaft oilier (well now we go by lubers) I want to know what exactly is so funny? I spit on those things if I have to JUST to get the job done...
how long did the China charger last you before it gave out? and at what psi were you running?
14psi, 28,000 miles and it was still spooling fine it just had a good amount of shaft play. I rebuilt it for $45 and it's been running strong for about 6,000 miles now.
It will last a lot longer than 28,000 miles at 14psi. You need to removed the restrictor fitting, journal bearing turbos do not need to be restricted unless you are seeing well over 100psi. Even if you have to restrict it, it would be very minimal. The restrictor you have on there is designed for a ball bearing turbo.
🔥🔥🔥🔥
I have my fears of China Chargers... but I've been reading up on RB25s from silvias/240s and I've read just as many bad things about the ceramic blades!
Does the Enjuku hold up well?
Holds up great, spools like crap.
TheCarPassionChannel Outside of the downpipe options, are the Nissan T25s with the ceramic blades still a better option? Assuming they are both the same price
I would go Nissan T25 with the inconel wheel, ceramic isn't worth the risk to me
TheCarPassionChannel would a nissan turbo have the same mounting as a garrett/ enjuku? like ordering the downpipe/ manifold from Begi, or FM... should everything be hypothetically interchangeable?
Shawn Hett If it's off an S13/14/15 yes. Z32 turbos are 4-bolt downpipe.
where did you get the cool compressor housing?
+David monterroza Bell Engineering will modify the turbo however you want when you buy it from them, so I had a 3" inlet put on it.
Most used turbo for sale say slight shift play of noise. will this rebuild kit fix that?
Even brand new turbos have slight shaft play, and what do you mean by "noise"? I have a recent video "How to Buy a used Turbocharger" that might help you out.
link to the rebuild kit please
the audio is dirty nasty low like ruddnik's miata
what up piiiiiiiiiiiiiimps ?
Is it a GT25 turbo or just a t25?
would a t25 be good for a 1.8? Also what turbo do you recommend for a 1.8?
+Nicholas Kondylis Same. They are great turbos for both engines, it will just spool a little faster on a 1.8. If you have a 99+ 1.8L, I would recommend going with a larger sized T25, like a 2560R over a 2554R.
What was wrong with the turbo as everything looked fine on dismantle?
The compressor wheel was contacting the housing
Does anyone have a link to a T25 turbo. I can't find one. Thanks
Will this stop the oil leak
