it should make a lot...depending on the tune/er.....id say with a good tune, 435whp....why go with 2871 .86 when the .64 makes the power and spools faster??

Thanks for the advice, i haven't bought the turbo yet and im not sure in im gonna go .64 or .86, just trying to get an estimate right now, what kinda psi should the built motor be able to handle??

2871R .64 wont make over 400whp due to the flow of the turbine housing. 2871R .86 is your best bet for getting over 400whp but its still hard to do cause the T2 turbine housing is pretty restrictive. I was able to get over 400whp on mine but i have a P&P Head and 270 Solid Cams. I was trapping between the 120-123mph in the 1/4.

Thanks for the information, im hoping to make atleast 400whp...

personally with the gt2871's your gonna be at the top of their effeciency at 400 hp if you can even get their, go with a gt30 and push less boost and ull still be there
