Default inputs on the GT2876r turbo

A friend is offering me this turbo $1100 bnew. i read its good for up to 350hp applications. it has a .82a/r t25 turbine housing and .70a/r t04S comp. housing. it looks like a gt28rs on steroids. with the 4" inlet is this any good for a street set up capable of 300whp??

I have tuned an Sr20 with that turbo and made 350, there is no reason it can't make 400.

Yeah it can hit 321 y0..
I am wondering if the original poster is talking about a gt2871r or is this a new turbo? Either way its not cheap.

Im in a similar position with this turbo, right now similar goals to about 300 hp, but with stock Ls. But if i was to build this winter would it be more efficient just to purchase the Gt30 range instead?
Sorry to thread jack but was curious.

it really depends on your goals..i think the 28rs is a great turbo...but if your shooting for more than ~ 350...i dont think you could go wrong with a gt3071, youll still have great spool and put out the power you want.

That's pretty much what I've observed, I had no problems making 408 with a GT3071R, and could have made more if I had wanted to. It didn't spool as fast as my GT28RS, but it was smoother and easier to control. For a street car I still like the GT28RS though, it spools at a very low RPM, responds extremely quickly to throttle input, makes 350+ at the wheels, and is the most fun turbo I've used by far.
