Re: Ford Probe 310 CC injectors
 

first you say you want 12psi on them, then you say 15psi? make up your mind.

id say at 12psi with a decent sized turbo like a t3, you're gonna be close to maxin em out.

I would defintely stick to 450cc DSMs. Your engine management can control how much fuel is coming out of them.
