Garrett GTX3071R vs GTX3076R

[@jovangarcia9363]

Sick video you know your stuff man!! You are the man!!!👍🏻👍🏻👍🏻

[@dangusprime]

Hey brotha! Want to get your opinion, trying to get as much info as possible for my build! So I have a 06-08 K24a2 swapped 8th civic. (Strongest 2.4L Honda has) and I am planning to Turbo it soon. I am looking at a Full Race Kit, but what's most important, as you know, is the turbo. I am thinking the GTX3076 would be perfect, I'm wondering when it would spool up and if would overboost the turbo if I didnt get the bigger exhaust housing, or if that housing would make it spool way high in the RPM band. Would a GTX35r be a better fit for the K24a2 just in general engine to turbo matching? My K24 is making 220 WHP 170 WTQ (@ 3k) NA with the lightest mods and tune CAI + Exhaust, still running stock restrictive K20 header + Cat. So the engine is pretty beefy and fiesty.

[@noeffect4131]

Great video mate, straight too the point no f**kin around!

[@Mr99ariel99]

Wich would you prefer for a k20 civic SI?

[@redtveagle]

Great Info. I think the GTX3076 is just the ticket for my 2011 Mazdaspeed 3

[@axelamps1279]

Did you ever do that? I've got a 3 MPS with the GTX3071 Gen2 and it's blown. I'm considering the 3076 but wondered what you thought of it.

[@floridaboyz89]

I'm looking to upgrade my turbo and my 2004 Jetta got a new thing?

[@scubagto420]

what kinda of difference am I looking at from going to a 3076 with 106 ar vs the 64 ar

[@sgt-willkillu]

@Turbo Everything Think of it as the 106 for top end, highway power. The .64 as nippy town driving & the .82 has a bit of both in the middle.

[@polskiewinnipeg]

are you going to be rebuilding one of these gtx 3076r anytime soon?

[@playingisgame]

Quick question... If i wanted to make 500whp on a subaru 2.5L engine all the way till redline.. Which would be the better turbo to use.... gen 2 gtx3071 or gen 1 gtx3076? Considering that what is important to me is for the power not die off before redline. I'm asking because. It's generally agreed that the gen 1 gtx3071 was a good turbo for the 2.0~2.2L engines... Not the 2.5L. So does the same apply for the gen 2 gtx3071?

[@lutherblissett9070]

X76 wheel is too much for the GT30 wheel. GTX3576R with a small A/R turbine housing is where it's at. Love your work though.

[@willduthie3836]

What about for a 4.5L v8 diesel motor?

[@YURICHAMORRO]

Kind regards, would I get a profit if I exchange a gtx3071 gen2 compressor propeller for a gtx3076 gen1 compressor propeller?

[@kaidendad9299]

What turbo do you recommend for a 13b FC rx7 Bridgeport looking for around 500Hp at the wheels. Or more.

[@sayfdyn1]

hey man i have 3 questions , i have the gtx3076r with .64 tial exhaust and i dropped a valve seat that destroyed the turbine 1 can i use a .82 using the same housing ? 2 is there a good upgrade i could do ? 3 whats a good place to buy these turbines or is it threw garrett ?i tried sending a dm but couldn't find out how thank you in advance

[@turbolabamerica]

The gtx3076r is the largest of its series, so if you want to upgrade you have to upgrade to a gtx3576r or larger. The gtx3076r is rated up to 580 hp, but the turbine housing size is the limiting factor. You can probably get a .82 turbine housing that is machined to fit the gtx3076r or gtx35r. I have replacement turbines on hand. We have our contact information on our website

Perfect I will contact you directly

[@sayfdyn1]

I emailed you but got no reply

[@alexmoore5970]

What turbo would you recommend for a daily/weekend warrior brz? I was thinking a gen 2 gtx2867r with a .63ar or would that be a choke point? My goals are 300whp on pump gas the FA20 seems to have good flow, does this seem doable?

[@Thr33.Sid3z]

I would go with the Gen2 GTX3071R... I ran a gen 1 and it was crazy! hit boost @2000rpms and full boost (30psi) @4800 on E85 in my 257 swapped gc8... it will leave you plenty of room for upgrades down the road. Great turbo for 300-500whp

[@THESKINIMIN1234]

Idk if you’ve done anything yet, but do some research into the available turbo kits for the fa20 and reach out to those companies. Most companies will be happy to converse with you and recommend the upgrades you should make or things you should replace, if any for your power goals with their kit

[@HLIASRS3]

Hi Austin can i ask you a question...??the ball bearings of the gtx3076-3071 and gt2860r gt2860-gt2871 are the same????if i order a kit from you it will fit all of these turbos if needed???

[@turbolabamerica]

+HLIASRS3 Yes it is the same, it also fits the gt35r and gtx35r. The Cage Changed to a larger cage with the GT37r /gt40/gt42r series.

[@Casper0878]

What set up would you recommend for a 2JZ GTE VVTI motor going into a Datsun 280Z with a 350Z CD009 transmission and a Q45 3.54 differential shooting for 500hp? Would really appreciate your input, thank you!

[@kaneradcliffe1521]

Casper0878 gt3071r. Made 504whp on 22psi on pump 98. Next to no lag either

[@kaneradcliffe1521]

Casper0878 only down side is that’s all I can really get out of it. If I want anymore power I’ll either need to run e85 or go to a bigger turbo

[@chownkay]

Hi Austin, what's your opinion on flank vs point milled compressor wheel. Which performs better? Is the difference a lot?

[@turbolabamerica]

+chownkay I have never heard of the term flank or point milled compressor wheel before.

[@chownkay]

+Turbo Lab America blog.steamspeed.com/2014/11/25/compressor-wheels-steamspeed-vs-blouch-vs-forcedperformance-vs-garrett/ How legit is this??

[@turbolabamerica]

There is some bad information online about this topic. Tims turbos has video of the billet wheel vs cast, He says that the billet wheels weight more because it is more dense, but it depends on the billet wheel. Some of the billet wheels we have are 20 grams lighter than stock and have a more aero design. They are designed the grab more air. I have no way to test a comparison between the 2 different styles. However, it makes sense that the wheels with the thiner blades and more narrow hub will flow more air because it has more room for more air to be grabbed. We use mostly billet wheels for the simple reason that they come in many different sizes that we need, they are popular, they make the turbos look good, they are a performance design, as well as with extended tips, and they are more durable over cast. Here is a weight comparison picture of the same size: wheel turbolabofamerica.com/holset-hx40-super-billet-compressor-wheel/

[@chownkay]

+Turbo Lab America Hi Austin, if you read the blog in detail, it's not so much discussing the weight of the wheel, or billet vs cast wheel. But more of how the billet wheel was forged, e.g. 3rd order geometry and flank milled vs point milled billet wheels..

[@dimitrisiliopoulos8339]

Hi Austin i'm sending from Greece,i have in my audi s3 tfsi atpgt3071r turbo kit with 11 blade compressor gtx3071r and I see in two different dyno dyno dynamics and dynojet 621bhp and 76kgr torgue in 2,32 bar.I wonder if I can see that power from gtx3071r compressor or they did mistake and put in atpgt3071r gtx3076r compressor;You are famous here in Greece with your turbo upgrades thank you very match.

[@turbolabamerica]

+dimitris iliopoulos are you talking about making that much power on 2 of those turbos? The s3, you mean s4?

[@dimitrisiliopoulos8339]

+Turbo Lab America I have audi s3 tfsi and I have the atp vvw-186 turbo kit with 60mm gt3071r with 11 blade compressor gtx3071 inside and I wonder if they make mistake and they put inside gtx3076 11 blade compressor because 621bhp and 76kgr torggue from gtx3071 is too match specially the torgue.Thank you very mutch for your answer,my question is if gtx3071r in 2,3 bar can have 621bhp from your experianse;

[@turbolabamerica]

You should measure the wheels.

[@jdportwerks6795]

Hey man so I have a built gsr 1.8 bored out to a 2.0 do you recommend 3076 or 71 it’s more on a daily/occasion race? What do you recommend

[@RoboDriller]

My 1.8t is laggy but pulls so hard on the gt3076 .63ar turbine.

[@RoboDriller]

I'd like to add one for 75,000 miles on a garret 3076r. It's probably do for rebuild. burns some oil under load now, filling the boost tubes. 4500rpm spool up starts t25 flange though:(

[@Thr33.Sid3z]

ur figures are just a little bit off. The Exducer on the GTX3071R is 73.45mm (2.05mm bigger than claimed) and ur saying that u wouldnt recommend running it on anything bigger than a 2.0L or 1.8L even? it makes great Numbers on a 2.5L. Ppl are making 450-500 with the gtx3071r. Its basically a gt3076r that spools faster.

[@turbolabamerica]

My reasoning wasn't based on the power that car could make, my reasoning was based on the turbo choking the engine at higher rpm because of the engine outflowing the turbo.

[@Thr33.Sid3z]

Turbo Lab America the Gtx3076r is the Mismatched turbo. it only saw 5-8% gains over the GT model. the gtx3071r saw 15-20% gains over the GT model. the gtx3576r was made in response to the poor performance of the gtx3076r.

[@TheChrisey]

Sounds like I need a 3076

[@pekoso1]

Can the same thing be done to upgrade the GTX3076 to a GTX3576 ?.... I have a bolt on GTX3076 on Evo X making 507 whp @31 psi and I would like to upgrade to GTX35 and make somewhere in the 550 plus.

[@turbolabamerica]

+pekoso1 If you currently have a Gtx3076r with a .82 t3 turbine housing you could go with a 1.06 t3 turbine housing and probably make the power you want. To go from the gtx3576r, that combination involves replacing the GT3076r turbine 55 x 60mm (6mm shaft bore) with a gt35r turbine 62.35 x 68mm (6.35mm shaft bore). Since the shaf tbore is different, the compressor wheel must be machined out, or the compressor wheel replaced. Its a lot easier for me to replace the wheel. The cost to do this upgrade is 550$, which includes the rebuild, machining the turbine housing, exhanging compressor wheels, and balancing the assembly.

[@Thr33.Sid3z]

true, but why would anyone want to run a 1.06 on a 30r when he can run a gtx3576r and make gt3582r power & gt3076r spool!?! The 1.06ar is just too laggy, even on the 30r.

[@Thr33.Sid3z]

im not 100%, but im pretty sure you can upgrade the gtx3076 with a 35r turbine wheel upgrade kit for about $600

[@turbolabamerica]

It's just depends on the size engine and the amount of horsepower someone is trying to make. Keep in mind the difference in the gtx3576 and gtx3076 compressor wheel is that the gtx3576 has a 6.35 mm shaft bore to fit the gt35r turbine and the gtx3076r compressor wheel is 6.0mm shaft bore to fit the gt3076r turbine. So the gtx3076r upgrading to gtx3582r does require having the compressor wheel bore machined out or replaced with the gtx3576r wheel but the wheel design is the same otherwise.

[@joseperalta8605]

what would you say is the spool diffrence

[@turbolabamerica]

There is no correct answer for that, because it depends on the engine size. The closer the turbo flow rates is in relation to the natural flow rates on the engine the more efficient it is and quicker the spool will be. It also depends a lot on the tune, intercooler volume etc

[@Masheen9]

OP is correct. There are a lot of factors in determining spool characteristics. The general rule is the lower A/R of the turbine housing, the faster the spool-up, the greater the low-end torque, and the lower the high-end power. A/R is the interior area of turbine (A), {or the cylindrical spout of the snail to get picturesque}, divided by the radius from the center of the turbine to the tongue (R). Since most turbos have an array of different turbine housing A/R's, you can customize the application of the turbo, and really just need to select the best turbo for your engine size and displacement.

[@ngt84]

Prpably after gtx3071 i would go gtx3576.... 3076 is mismatch

[@tristarO1]

which should i put on my sr20 if i get one?

[@Thr33.Sid3z]

Gen 2 Gtx3071R will throw down a solid 500hp on the SR20DET

[@motion2597]

What is the best turbo 2015

[@turbolabamerica]

+Son Goku It depends on the HP you are trying to make, and the size engine you have.

[@Thr33.Sid3z]

gtx3071r with 82ar for anything under 500whp and the gtx3576r with 63 or 82ar for anything from 500-650... looking to make more power than 650 i would look at either a gtx4202 gtx5518r or a 6862 even!

[@jelaniwilliams2697]

hey great Vids, can you do a gtx3576r Vs gtx 3071r, and recommendation for a rb25de+t for great spool and transient response and top end. Goal 350 -400whp. if not a video a comment or reply, much thanks in advance.

[@martinlee2656]

just go with t51-33D twins

+santiago8698 If i dont repond, resend it. Sorry, i was gone for a week, i just got back yesterday, im trying to get caught up on my email responses.

[@timc898]

Would this gtx3076 be better on a 3 ltr for 250-300kw manual instead of a gt35/40 with a. 62 etc? which everyone is recommending. I don't want huge lag and big power more a all round Street car

[@dennisrobinson8008]

4y old response. In a 2jz the Gt30 .86 are beat .64 ar across the board. Gt35 .86 ar was beaten to around 5000 where it lagged by 700 rpm. It made about 20whp more. For a street turbo the gt30 was superior with 100wtq or more at many rpm points.

[@mileswatkins6472]

Can the gtx really put out of 550whp ?

[@Thr33.Sid3z]

Gtx is just the model, not the size of the turbo. To answer ur question tho, the smallest Gen 2 gtx series turbo to make 550 is the 3071R, It will make 0ver 600awhp and the gtx2867R might make close to 500whp... I made close to 500 with the Gen 1 gtx3071 .82ar on E85 EJ257 w/2L heads, so the Gen 2 will make a bit more!

[@playingisgame]

+Evol_AF did it pull all the way to redline or it run out of puff?

[@Thr33.Sid3z]

My STi RA had a 8900RPM Redline, but it would hold 30psi to 8500 and fall to 26-27 at Redline. With a 9k Redline i rarely needed to hit redline. It hit peak HP @6500 & TQ @5600 and didnt fall off untill 8500 The gen 1 gtx3071R was my fav 30R sized turbo, but best all around IMO is the Gen 2 gtx3576R.... Power & Torque with little lag on a 2L & very little lag on 2.4-2.5L

[@playingisgame]

@@Thr33.Sid3z I'm looking for a turbo that pulls all the way till my 8k redline on a 2.5L. My options are a gen 1 gtx3076 which i currently have or a gen 2 gtx3071... What would advice...? I'll mostly be drag racing on race gas.

[@dennisrobinson8008]

​@@Thr33.Sid3z saw that the gtx2867 was making well over 400whp like you said. How much earlier does the Gtx2867 start making boost vs the gtx3071 and gtx3076?
