Buy my SP61GT listed in the for sale section. Bolt on, ready to rock, still under warranty until May06.
With that said, good luck getting any info from the folks that sell bolt on turbos for our cars.
They sell them and that is a plus, but they won't or at least have not, installed them on a car for before (CT26) and after (upgraded turbo) dyno numbers.
Mine rocked at high rpms, but was in my opinion laggy.
Can you make 500 on it, I believe so with boost levels at 20+psi.
