- FULL BOOSTED RESULTS. BIG POWER, JUNKYARD TURBO LS. Just add a good cam, decent springs and then boost. The trick is to make sure you have enough fuel, the right fuel and proper intercooling. Little things make a big difference. Of course you need to choose the right turbo sizing.
Johnny Sins, he taught us how to perform in the sheets, now he teaches us how to perform in the streets.
🤣🤣
I'm dieing right now 😂😂😂
😂😂😂 all around performances!!!

I'm going to need 20 more videos where you mention ring gap because it still has not sunk in yet. I will probably need my own Big Bang before it does.
Every cam is a turbo cam is finally sinking in.....
Thanks for not giving up on us stubborn ones.
Couldn't agree more
It will happen. And while you decel blowing smoke from a ringland popping you’ll kick yourself over and over. Ask me how I know
My understanding is that ring gap is a free "mod" you can do so you dont trash your pistons. Cuz that's expensive. It will burn a very little amount of oil but not enough to matter due to blowby is my understanding. It's a trade-off that is worth it.
I am fairly confident I can build a 800 hp engine thanks to these vids.I never could do that in the Small Block Chevy days.Thank you!
Very handy tool to have. Richard Holdner TH-cam subscription!
Australia has no idea. Thanks for teaching us. Keep it up mate.
Australia has been at the forefront of Performance ECU development for the last 30 years. The holley stuff popular in the USA is still years behind what is developed here.
@@manitoublack I'm not claiming I know a whole lot about ecu's but I do know this I'm a real big fan of keep it simple stupid!....
@@manitoublack what's top of the line? Haltech? What can it do that Holley can't. Serious question because I want to know.
The last 30 years? You tripping? If it wasn’t for the US we would still be playing with cute lil 308s. That’s where Australia learned all its tricks mate, the day the mighty ls1 5.7 was born!!
thank you for all of these videos. i thought i recognized your name from the dozens of articles i have read by you on LS cams and heads
I've opened up 3 separate gen 3 5.3s and the ring gaps have been ALL .015 top ring and .017 bottom ring. One of them even had 302k miles.
Just badass! I've watched dozens of this guys vids, tons of turbo vids. Hands down the best smart budget build i've seen.
Glad you liked it!
This is exactly what I wanted to see! Juicy juicy details!
Hey Richard thanks for your video's. I'm new to this Ls turbo stuff and you really help with different questions that I've had. Keep up the great work and video's
Thank you for all the great information!! Would love to see a video on the tuning process if you ever have time to squeeze it in. Thanks again!
Think I might add some ring gap before I put my fresh built 6.0 in my truck. BTR stage 2 cam, LQ9 pistons, valve springs. Boost could be fun also. I'm learning alot from your videos, keep em up!
So impressive the amount of low buck power from the LS and boost. Learned so much from these videos! I wish I could fit it in my box Nova no room. But!! I might now with the exhaust manifold backwards sending the exhaust forward. I’m Going to check thx Richard!!!!!
My 4l60E requested that I stop watching your videos.
Thank you for doing this it helps me out choosing the parts that I need which is not a whole lot to make decent power you are the man thank you again
This is exactly what I needed. Thank you.
I remember asking you about this, with my LS6.
This vid made me excited to finish my build and get it on the dyno. Similar set up, but summit stg 2 turbo cam, milled .030 243 heads, tbss intake manifold and 92mm throttle body. Gonna run e85 as well, but around 20-25lbs of boost. 😁
Fabulous results and excellent advice as always.
I can only imagine what you could accomplish if you had a motor that wasn’t designed to be a bilge pump for the ark.
I think I'll build a turbo setup this spring for my LS truck
Richard do you /or will you ever do a test with 93 pump gas and water/meth as an alternative to running e85?
I would like to see that as well
I’d like to see this
One of the big reasons he doesn't do that is in a previous test they found that the water/meth has very unequal distribution between cylinders.
Direct port water meth? 😁
they did a big test on pretty much every differnt fuel on TheTuningSchool youtube channel
Your videos have improved in leaps and bounds in the past few months! Keep up the good work l. Also an idea I’m sure people would love to see a walk around and detail video of your mustang that did the silver state classic. Or any other cool cars you currently have !
Could you do a test and show what the results would be if the turbo is remote mounted like 8 to 10 feet from the engine as compared to with manifolds and a y pipe like this video? If you do i would love to see the charge temps, lag and the likes. Thanks, Richard your videos are Awsome.
That would be an awesome test, but I suspect it would make little difference on the dyno here since it's wide open throttle and under load.
Yeah, apparently you can't really see things like lag on the dyno.
I too would love to see this test. Especially on a slant six.
@@nowayjose596 Yes you can. Won't be the same as in the car, but you can still compare transient response from one turbo to another, or one hot side to another. Still very valuable info, assuming the way the test is administered is same.
I love your work. Please work a 5.7 LS1 into your collection. We don't see 4.8/5.3 in Australia, unfortunately. Also, something tiny and modern like a Suzuki K12C for big bang.
He has done bigger cube, they respond pretty much the same. just from a higher baseline. So if a 5.3 is 300hp NA and 600 hp boosted then the 5.7 will be 350hp and 7000 hp boosted.
@@cuzz63 dang thats a lot of boosted power 😅😅😂
Really what he's testing applies to any engine. I only really mess with Mopars but I enjoy Richards videos even though he mostly does LS's with a couple Ford's and hemis thrown in. They all do the same thing.
Hey thanks man. Much appreciated info.
Thank you very much Richard. I'm only beginning my journey of learning all the mad scientist language and what all the different specs mean and all the terminology. I'm new to all this but I understand all of it in the general sense. I'm just a normal back yard mech but I'm learning a lot watching your videos and others. I have a 2003 z71 avalanche with the 5.3 ls. There's so many things I want to upgrade on the engine. Your video touches almost everything I was looking for in a single video. Could you make a show on what happens when you have a stg2 cam, cold air intake, ebay turbo, and long headers with straight pipes? I know I have to change the springs and lifters and injectors and it will need me spark plugs all of which I was going to have to take it to a shop to be cleaned up and tuned up again anyways.
plenty of turbo 5.3l vids up to show you what boost does
I want to see some 8,000rpm test motors :)
That 4.8L is really perfect to do a 8,000-8300rpm turbo test with. Like squirrel tuned twin S366’s or even a S480-S485 or even a low boost 102mm turbine turbo to show you can make 800hp on low boost at 8,000rpm with a 4.8L.
You’ve def hit the nail on the head for all the “I want boost and burn outs 500whp crowd”. Now let’s step out the box !
Stock vs Stamped vs Aluminum vs Shaft rockers would be interesting to see.
Thank you so much if you could follow up the correct paragraphing after the initials it would be greatly helpful suggest things like what does SBC mean on and on thank you for your time
Really made me think, I’m looking to run a boost 5.3 in a Miata and figured 500 hp and low boost would be all I would need. With my audio in my station wagon I started with 2 10inch subs and said it would be plenty…. There are now 3 15 inch subs and the box is as big as I can get with keeping the rear seats. I wish I had more bass…
Great video I enjoyed it thanks for sharing your knowledge
Something I didn't catch mentioned in there actually has nothing to do about the engine but the infrastructure around the engine; I'm talking the axle and transmission in particular with secondary on suspension. Having an E85ed LS engine is a heck of an upgrade for a lot of chassis.
Also awesome way of collecting thoughts on this. It's something that seems to have a lot of precedence of working very well around it. There's a reason it's common.
thetriode agreed, I’m working on suspension, trans or rear end whichever chance comes first, THEN the engine. I’m looking for 700 hp lol
There’s a Lotta good information thank you
You r awesome thanks alot for your hard work n info👍🏽👌🏽
I'm running the same cam in a 200K mile 5.3 with a gen 1 7875 turbo on 13 lbs. It moves my 96 Silverado pretty good
I've watched all the videos and this is by far the best.
Hit that like before I watched the video, crazy how this content dosent have way more subscribers
Love the videos. (Pls grab a wirless mic off Amazon) Great audio makes great videos. Thx for all the awesome info on LS engines etc
I have one
"If you're gonna upgrade the cam. You need to upgrade the springs" May I suggest upgrade the rockers to a roller tip. I couldn't find out why I wiped out the trunnion upgrade. I had plenty of oil... I talked to Kenny Duttweiller and he said the stock rockers cannot handle anything over .600 lift. The arc of the rocker was designed for .550- .565 at most....
There are thousands of 600+ lift cams on stock rockers, I doubt that's the problem.
@@thomaslane8944 It was an issue in my situation. Kenny Duttweiller has seen a lot of failed stock rockers at higher lift. That's why I listened to his advice and went with the roller tip rockers. If you go to ls1tech.com and look up "trunion upgrade failure" it's happening more and more as people are starting to get miles on their upgrades....
@@yinzer_412_ Was it a bearing or bushing style trunion kit? The bushing style has proven to be very reliable. Those roller rockers are going to cause valve float if you try to spin it over 7500rpm.
Richard is the man with Great engine info for just about anything going now!!! Great info as always💪🏽💪🏽💪🏽
Bloody great mate keep up the good work I love your real life approach. So good
I'd really like to see a from junkyard to jewel series.
Show us what we need to snatch from the donor.
Show us the breakdown and reassembly process. What all do we look over and change.
Reassembly and turbo selection.
All for less than say $4k
Another great video Richard, thx. Well done
I have people asking about doing turbo ls installs and the hardest thing to explain is how many mods you have to do to make sure the fuel system can keep up . Like running bigger fuel lines and figuring out some kind of pump system . The fuel system can cost more than the turbo.
Lines don’t get any bigger then stock. You’ll need to up the pressure. Pumps aren’t to costly. Many TH-cam videos on the subject. My upgraded system cost so much just because of the unnecessary AN fittings and lines upgrades I made. Otherwise, pump, regular, injectors, line filters. In my case did cost more then an eBay turbo for sure. Cheers
This is crazy. As in crazy good. Who can thumb down this? That makes a fun daily driver.
First , Richard I enjoy all the content that you have been putting out. Great stuff. Love killing the myths! Lol. Now for my question. I understand that the cam is the brains of the motor but the supporting stuff is important as well. So here’s the combo I’m attempting. 5.3 , 706 heads , truck intake. 4L60e. And it’s in a truck. I daily drive and tow once a month. Years ago you did a test on a camel that made power and torque everywhere in the curve over the stock cam. I can’t find that test. Second. I may have to remove my 706 heads as possible coolant leak in casting. What do I replace them with? Another set of 706 ? Not looking to rotate the earth just a healthy daily driver Your thoughts. One problem wt the computer is it’s much like on line learning. It’s only presented one way and no questions. I’ve noticed you seem to answer questions. Thanks again for your efforts.
Great stuff man. I love the detail would love to see you show us your square body.
It's not that type of channel dude! 😂🤣💪
Morning Richard. What spark plug gap do you use for turbo ls builds?😺
the typical is between .020-.030. Turbo stuff typically likes a tighter gap than blower or N/A
It doesn't get old but there are variations we would love to see... Like the pump gas & water/meth suggestion. I'd love to see pump gas in the engine and e85 with the nitrous.
I think a good test of the 706 heads, stock vs mild porting vs max porting vs a good aftermarket head... Like us average joes go through. Either way, awesome video! Keep making them and I'll keep watching.
Hey Richard im in the process of boosting a 5.3 my question is we dont have many e85 stations how much of a HP lost would you see on pump gas with the same setup on this video? Thanks
Let me know when you start finding deals due to CV. Prices have been holding steady. On the lookout for a LY6/4L80 from an Express van.
Awesome video Richard! I love the boiled down vid for layman like myself. When I do my 4.8 turbo. I’ll just save myself the drama and go straight to 18 lbs. 🤣😜 as always. Love your vids!! 👊
Boost curve? Back pressure curve? Timing? As someone else noted, it didn’t follow the boost power formula... Still, love this channel! That Summit stage 1 cam is amazing! Comment on CR: I think you said once the JE pistons had a 7cc dome. If true, that’s almost a full point of compression, 10.4 vs 9.5. On a 400 hp combo, that should be worth 15 hp or so NA. That makes a difference. I also vote for the meth injection camparo, 91 octane and say 15 psi compared to E85 (which is nice but hard to get day-to-day). Maybe move the meth injector farther away from the throttle body to perhaps get better distribution? You’ll have work for another decade, I think!
Very cool. I had a combo in my head now for awhile and a turbo in mind as well. This setup you done is very close to what I had in mind. Very pleased with the hp numbers. Was wonder how the gen 2 would work on a 4.8. Seems to take the boost well. Very cool video thanks for taking the time to make it.
Great Information as always Richard. Like others that are not USA based, e85 is a no go for us. Could we see a pump gas shoot out? Maybe a don’t BS me build on e85 and then pump? Please continue to provide content. It’s really good.
Have you done anything with the 8.1 and our family loves you videos thanks for the content tips tricks and all the knowledge we appreciate it
not yet
It's easy to find the torque curves. They cross the corresponding power curve at about 5353 rpm. Even without color coding, this would be the case.
PS: the torque curve will be lower than the power curve after 5353, and higher than it below 5353 rpm.
5252
What kind of fuel pump with decapped 80# or those snake eaters? I'm sure my stock s-10 blazer 4.3 pump is insufficient. I'm building an 03 Xtreme street Blazer. Stock 4.3 v6. Pretty sure I I got 4.8 even though the guy told me it was 5.3. It has flat tops. Very clean . Supposed to be 104k on the clock. I've bought a sloppy stage 2 and sloppy springs. lol I'm using Terminator max 4l60e with a 3000 stall. I have an 80e but thought I would eat the 60e first. It was behind a 4.3 and seems strong still. Just now starting to think about boost. I got 706 heads but after seeing your videos about ring gap and the small but great combustion chambers I may run a cheap GT45 with 8.5 # lol. Really 500 rear hp would be just fine. I'd like to street drive it. The rear end is probably a huge weak point as well. I have a 67 Mustang coupe resto mod I want to do something with as well it is kinda weak. Looks great though. Fords are just a pain though.
At the end of the day I'm looking for torque , problem is I want it to pull hard all the way thru.
Good video and excellent explanation of what's needed to easily pull power from a stock LS. I know that this is a rookie question but would you recommend getting an engine from summit racing or jegs if a person did not have the necessary knowledge, space, tools, or finances to get an engine from a junkyard to rebuild? Thanks
THEY HAVE GOOD STUFF
Jeezus, thats a good result!
Still need to do a barra !
Ring gap is Richard's version of Jeff Cavalier's face pulls.
Have you ever looked at gap-less rings that have an overlap wedge/step. I remember reading about them back in the 90's but have never actually tried them.
they work
Great job brother, keep up the good work.
Another no timing info, too crazy to comprehend
Richard, the Summit 8720 218 outperforming the SS2 is pretty impactful to people who default to a 23x cam choice. I’d really like to see you fill in the gap between the 8720 and a BTR torque cam. Please see if you can get Summit to give you a 209/217 high lift truck cam. If that performs great down low while giving strong HP like the 8720, it could be perfect for a 4.8l street/strip motor - not race, but partial throttle would be great.
Richard, your videos are awesome. Thank you for the info. I do have a couple requests. Spark plugs - tell us what do you run and why. If I call NGK they tell me to run the newest iridium plugs, my tuner says use a copper recessed. Also exhaust. Recirculated waste gate vs open dump. AND the big question for turbo setup I have is exhaust. What is the best street friendly setup to run? Can a turbo setup make good power with catalytic converters ( I have a 3" down pipe to dual 2.5 all the way back)? Or run test pipes between emissions tests? I have a 98 s10 4.3 V6 with a 62/68 t4 borg warner. Trying to get it dialed in. Having some issues with cut out when boost peaks at 4,00 rpm. Thanks you Jim.
we use Denso or NGK plugs-heat range 9 or so for boost-we run the WG open to atmosphere, power will be down with a restrictive exhaust, but it can work
I like heat range 7 or 8. A catalyst and/or quiet mufflers will certainly cut power substantially - but who cares? 450, 550, 650hp is plenty. Don't get hung up on making some specific number. Ultimately you're trying to add a bunch of performance, right? Well, that can be done quietly and with emissions compliance if you care to.
Sounds like a game of just the tip
So what's the ballpark cost of a setup like this, not counting in fabrication and possible wrenching hours? And maybe some kind of hp/USD figure might be interesting also, just for people to figure out what their budgets, needs, and hopes are, and how they align.
Run a 4g63. I've never seen that before. Also thanks for all you videos. They've been extremely informative and have helped me with a few turbo LS cars I've had issues with. Thanks again!
Can you do a video on how to change ring gap?
When it comes to ring gap my problem is that I have already installed the engine completely into the car. Everything on and hooked up. Id have to completely remove everything and tear it completely apart. SO...This motor gets no ring gap. The next one I'll be building in the mean time will get ring gap.
Yeah, I agree but it wouldn't be too bad if you pulled the engine, pull the heads off, oil pan off and just knock the pistons/rods out and gap the existing rings. New head gaskets, re-assemble to spec and re-install. Problem is, we all think it needs to turn into a $5000 job with new rods, pistons, studs, oil pump etc. It could be done and wouldn't be that painful if stick to the job at hand, lol.
Great videos my question is if I’m upgrading a junkyard engine for boost in the future! BY OPENING the ring gap for boost! what effect will the extra gap and blow have Especially with a NA engine until I finish off the turbo set up ? Can I have my cake and eat it too?
it won't change the na power
Question.what is the timing map,and tune set up.i get the hardware.the software part I need info.yes holly computer.but what about the tune on ign and the overall map?
Don't use too much timing!
@@GroovesAndLands copy ,thx for reply .
Awesome power!
Hay I have a 4 digit Goal because of your videos
Did you happen to make any pulls on boost WITHOUT e85? Very curious in the lower boost range what you would see as for a true DD a lot of us prefer to stay away from the corn switch over. Thanks as always for another video!
I have not
Hi Richard. Can you do a test where you torque the main caps vs non torqued main caps and see if it changes the ring gaps. Also a test to see just how corrosive e85 is.
Main cap torque will not create a discernable difference in ring gap. You can barely detect the change in roundness with a 0.0001" sensitive bore gage - and ring gaps need to be right +/- .003" or so.
GroovesAndLands be good to see if there is a difference between the aluminium vs iron blocks
@@wademunyard9026 Sounds like a waste of this mans valuable time to me
Hey Richard 👋, thanks for all the knowledge! I'm just curious at what rate would your dyno translate to whp? Tia
there is no strict conversion-since it depends on how we test it on the engine dyno and the drivetrain and other parts used in the vehicle
@@richardholdener1727 gotcha!, makes sense. Thanks man, greatly appreciate your time and Thanks again for all the content
Good job mate
The people that are against gapping junkyard motor rings: they won the lottery and found a motor with looser than average gap. I've seen reports of people checking multiple blocks and finding a few gapped less than 0.010". Barely enough for stock power.
Also: holy surge, batman! Seems like that BOV was stuck shut.
I have an 8.1l vortec I'd like to add boost to. All the info says weak pistons and rods but now I'm thinking could be a ring gap issue like you mentioned many times.
Ring gap won't make up for "weak" hypereutectic pistons and cast rods. The motor will still blow up, but instead of finding a piston ring and skirt pieces in the oil pan, you'll find piston sand and a small hole in the piston head. Torque is what breaks connecting rods, and those 8.1s make radical torque.
At 18 lbs of boat. What was the spark degree ? What was AR? What was fuel pressure.
Not a lot of E85 pumps around. How would this setup do on 91 octane? That's the most readily available fuel in my area.
E85 ... cheapest race gas full stop!... we live in a great age for performance that’s for sure
In some places. Some states (and pretty much the entirety of Canada) E85 isn't available at the pump, and buying it by the barrel does a real number on the cost effectiveness. Still worth it for a toy IMO, but on anything that gets lots of miles, 91 and methanol are a better solution.
e85 is hard to get in long island NY
Unless u live 25 miles from a station with e85....
In all of San Diego county (big fuckin county, 4500 square miles goes from the border up to Orange County), theres 6 gas stations that provide E85. Nearest one to me is 14 miles away, and I'm lucky that ones that close. Between that and the fuel system upgrades, bigger injectors, 25-35% reduction in fuel economy and corrosion of aluminum, I'll pass.
*Do you gap the second piston ring also?? .028” is what I do or .030” on the top one only??
i do same on both
Look! at that Rod bending mid range TQ. Dang!!!
The rule of thumb with Gen 4 stuff is keep the torque under 800 lb/ft. At 8000rpm, 800 lb/ft is over 1200hp.
What about Gen 3?
I know Richard has pushed them on the dyno, but I would probably stay under 800rwhp to be safe.
I think it would cool if you could do a test on a 1000hp +build ls . Run it with the stock ls exhaust manifolds and then with a set of flow tech turbo headers .I think people would really want to see if the headers gain you much
Mr. Holdner, when you are adjusting your Tune on a Carbed turbo engine how are you able to detect high speed detonation???
Do you have some kind of Stand Alone knock sensors??
no knock sensors
No knock sensor so what's the timing
Really want to see more gen v stuff I'm getting ready to build my lt1
Most 1st time boost guys don't have the skills to do ring gap correctly without causing themselves more issues than its worth. Example = improper torque on rod bolts, head bolts, re used head gaskets or NOT, ETC.
Also what would you run other then e85. It's all we here about and we don't have that up here in Canada on the east coast. So what chooses do we have for say 800ish hp?
Dear Richard,
Would you please talk about JUNKYARD TURBO LS for "Drifting Application" if you would? I mean witch setup can make Turbo Ls responsive, Low Lag "Creating Boost Early" and at the and time with Low Back Pressure.
Small Turbo Size "68MM" related to Ls Capacities 4.8,5.3 6.0 . There is a lot of guys drifting with Turbo Ls. If you make it in Happy Hour and Horse Power Talk, you gonna be best of the best. Good Luck and keep forward.
“If your aiming for high 4 second passes, you’re probably not watching this video” 👀🤣
He said 4 digit power numbers not ET's, but the concept is the same, lol.
Thanks for this awesome Mopar vi... Oh what, it's an ls ;)
Would live to see a test on the ITC billet adapters .
You say the factory ls3 intake is the best stock one .
How would it fair when used on cathedral port heads ?
Also thank you for all that you do .
Have any tuning videos ??
Great info Richard! Too many ads & the placement of them is in the way. Otherwise another great video!!!
Could doing a compression test give an idea of ring gap? Or maybe how much leak down on a cold engine over a certain amount of time give an idea of ring gap?
I dont think ring gap will effect cylinder to ring sealing.
There is no way to determine ring gap by measuring cranking pressure with a compression tester. Sorry
Do you only run 28-30 on the top ring what about the second.
I've asked this before and I believe he does the 2nd ring the same.
a lot of the piston manufacturers say the bottom ring needs to be gapped WIDER than the top ring. The OE does that. If you're doing super high boost like over 20lbs, I don't see a problem doing .028-.028, but I personally don't see the gain if its going on the street. On the motor I just built, I followed Wiseco's recommendations for street boosted (motor has 11.5:1 compression, will make 600hp N/A) and did .022-.027. That still gives me enough gap for boost down the road (less than 17lbs IMO)
How consistent is E85 at the pump. I’m only asking because of the tune ? Would you need to adjust the tune according to content ? Thanks for all your hard work and free info.
Varies between about 55% and 75%, generally. Yes, it makes a difference but not a giant one. Best to use a flex fuel sensor that detects the percentage real time, but if you tune for ~11:5:1 AFR with E85, you won't break your engine with seasonal fluctuations in alcohol percentage at the pump.
