sr20det/ gt2876r

[tulsa240sx]

hey, I was wondering if the gt2876r had the same bolt on pattern as my stock sr20 turbo? I have been talking to some of my friends and they said that that would be a good turbo swap for my car and I was just wondering how that would work out. Thanks for all the help!

You have the option to get one with the stock T2 housing. But from what ive read from people who ran them, theyre pretty laggy. Preference is still on the GT2871R due to the smaller hot side.

how much hp do you want??? and i hate the 2876... get a 2871r, or a 3071r.. the 2876 is pretty much just as laggy as the 3071, and puts out less volume

[JacksonBrown]

Yes it does -- in fact it mounts to your stock exhaust manifold too. Great upgrade!

EDIT: Misread, you said 2876, not 2871. I agree with ^^ go 2871.

[tulsa240sx]

ok, thanks. Do you know about how much Hp that will get an sr20 up to?

you get more power out of a 2876r than a 2871r. its right in between the 3076r and the 2871r. i have a 2876r on my 2.35L sr and it is not laggy. but that is just because of my displacement. you get over 400whp with the 2876r without a problem.

[Silviaslider22]

you can get over 400whp with the .86, the .64 is not going to see over 400.

GT2876R and GT2871R have the same hotside - hence the '28.'

I have a 0.64 A/R version that I got for a decent price - it spools up almost identically to a GT2871R 0.64 A/R from the seat of the pants. Going with 264 cams over stock cams makes way way more of an impact on low end and spool than the difference between an extra 5 mm on the compressor wheel exducer in comparison.

what i ment to say is that you can hit over 400whp easyer with a 2876 .86 than a 2871 .86 and you can go about 50whp more than the 71r with the 76r.

but like stated above, get some cams and that makes a world of a difference.

Would you recommend it for 360-80hp at the wheels? I just find it attractive because it doesn't come internally gate, and I'm already setup for external gate with my t2 manifold.

Setup:
-dw 650cc injectors / z32 afm
-hks 264 step 2 cams (with RAS, BC springs / retainers)
-freddy i/m
-enthalpy tune
-custom external gate setup


Just worried that it would be super laggy.

If I were buying new, probably a GT2871R with a 0.64 A/R housing and just live with what you get. The step to a 0.86 A/R housing introduces a lot of lag for the ~30-40 rwhp you can get over the same .64 setup.

A GT2876R is internally gated in any turbine configuration - in fact, the hotside options are IDENTICAL with the GT2871R offerings. The only difference is the compressor wheel and the compressor housing.

[Ninjabread]

Huh nevermind, I don't know why I was thinking it was externally gated only.
