572 that revs to 8000rpm.. holy ---- man ive never heard of that.

u could go with 1 turbo something like 1.70 a/r will prolly put you around 3500-4200 i would imagine but i really have no idea..

talk to garett and see what they suggest though. but that/those turbos are not gonna be cheap man.. same with the 60mm wastegates u will need to use.

i chill goes down my spine just thinking about that cost.

good luck thats a bitching powerplant.
