Sorry for digging up a 6 month old thread....Just curious if anyone has ran the On3 or VSRacing 88/83 turbo? I believe it is the same platforms at the 7665 and 7875, just bored for the 8883 wheels. Wondering if the smaller housings with bigger wheels would make more power than the GT45 framed turbo with the 80mm compressor....

Okay that is good to hear. They are not cheap turbos but if I build all my plumbing for my on3 7665, I can make 2 upgrades down the road....the 7875 and then the 8883. But if I choose to do the GT45 then all my plumbing will need to me modified which I do not plan on doing. If the 8883 can hang (800+whp) on <20psi on a forged LS1 then I will continue with my plan. Otherwise I am going to start with the VSRacing/CXRacing 80mm BB GT45 platform so I only do plumbing 1 time.

I made 658 rwhp on the 88/80 from VS Racing on 14 psi with a small cam through a turbo 400.
