Turbo Discussio

[bmadd2402]

I have come to the conclusion that my goals lay somewhere between the GT3071R, and the GT3076R.

I have read people's comments that a .63 A/R turbine is too small for an RB25det. Then I have read that the .82 is too big. is a .82 good for a 3071 but not for a 3076? At what point does it become restrictive or create excessive lag?

My car is an RB25DET, ported head, valve job, stock bottom end (checked bearing clearances, solid comp & leakdown), fresh gaskets and seals, FMIC, 3in turbo back, with plans for AEM ems, and injectors and cams to support new turbo. it will see track duty, and some drifting, so functional power is the goal.

Sorry for the long winded post, but a brotha's got nothin but time in Afghanistan. Thanks in advance!

IMO your best bet is to keep searching online, find someone who has a simaler setup to what your going to be running and copy it.

Either that, or call someone who sells turbos who really knows the answer.

I got mine from a turbo dealer after I told him what my car was, and its fine. I think the .63 may be a little small A/R wise but its a good driver for sure.
