Someone post their 2.0L gt3071r setup!
Trying to get an idea of how much boost I need to pull out of this turbo to achieve 350-400whp on a built 2 liter.
Please post your build as well, dyno charts are a bonus
Also tell me how you like the turbo and what your impressions of it are.

It's about 50lbs/min, so about 16-18psi of boost pressure assuming a good volumetric efficiency of a VTEC head in order to get about 350-400whp.. So a bit better than a T3/t04 50 "trim" turbocharger. Not many use that turbocharger on this forum. Sadly, people look at peak power and go straight to a GT3076R.

Re: Someone post their 2.0L gt3071r setup!
I was afraid you'd say that, about this forum I mean. I don't want to be like everybody else and buy the biggest, baddest, most popular turbo just to say that I have it and make 1,000,000 whp. I am trying to really do my research and not just depend on whatever everyone else says but actually LEARN why and what kind of turbo I need for my horsepower and driving style goals.
That said, my real question is whether the gt2871r or the gt3071r is better suited to my build. I realize that these are relatively small turbos compared to what people are putting on their cars these days, but that's by design. I want a broad powerband from mid-range pulling nicely through the top end to see between 350-400whp. I'm afraid the 28 series will "run out of breath" by the time I hit 8-9k but I will lose responsiveness with the 30 series or surge at lower rpms. Any ideas? I should mention that I am new to boosting so forgive me if what I say seems stupid.

you are probably right about the 28r falling off up top at 400whp. if it will even reach it. the spool time between the two turbo's you mentioned are probably only a couple hundred rpms.

I laid down 353 on a gt2860rs. This is maxed out. Go with the gt3071r.
I just picked up a GTX3071r .62 A/R. Haven't gotten it on the car yet but I am excited :D

I had a better feeling about the 30, thanks. I was also wondering if it was worth adding the ported shroud compressor housing option, does this actually help prevent surge, or is it all for show?
