Hey. I've got some plans for a blow through carb 12 setup, but I'm trying to figure out which turbo to run. I was thinking s5 TII turbo maybe, how much can I source one for? I need something somewhat cost effective, but I want to get power and responsiveness. I'd like it to spool up pretty quickly, and I'm thinking 14 psi or so on the s5 TII turbo if I get that. Is the TII turbo a good choice? Is 14 psi too much? How much can a 12a with hardened stationary gears but stock rotors and compression (doing a rebuild + doing stationary gears and streetport) take? Thanks a lot.

The TII turbo is a great size for it, it will spool quick. The stock 12a won't take more than 16psi before it starts blowing oil out the dowel pins. But 14psi will be fine. I usually keep mine around 12psi as after 12psi the TII turbo starts getting very inefficient and producing much more heat.

 

wow, thank you very much! i have been looking for just this info!
