Turbo PI 2v build
 

Bought fuel system and turbo kit to run e85. Car was "stock" motor so he says on 12 lbs. Is that safe on stock motor ?

Sounds like a lot. I am guessing that will double the power of a stock motor and I doubt it will hold for long-term just because of that. Your best bet is to talk to whoever is going to tune your car, as they likely have actual experience with that stuff.

I would personally run lower boost like 6 or 7 pounds unless my tuner believes a higher figure is still conservative.

12 psi from a turbo is gonna nuke that stock bottom end. I'd shoot for more like 8 and see how things look.

from experience 12 psi is too much, I was running 10.5-11psi and nuked my stock motor in one 2-4 pull lol

stick to roughly 8psi... its all about the torque. Thats what kills motors
