Best CR for built IP motor with 3076r
So im in the process of rebuilding my motor because of some scoring on my cy walls. I am going to stay with the turbo i have now a 3076r .82a/r because i love this turbo for the street, but i want to get the most amount of power out of it that i can. I am running a water meth kit and plan on running only 93 pump in the car(no race gas ect.) My main question is what would be the "best" CR to go with when i get the motor built? From what i understand this turbo runs out of effeciency over about 20-22psi(correct me if i am wrong) so im thinking that i should go with a higher compression for the set up i have cuz i would have to push the turbo if the cr was lower, and thus creating more heat. If i go with a slightly higher cr 9.5 compared to 9.0 i can get a few more ponies at a slightly lower boost level. What is a safer play for the motor; pushing the turbo to the edge of its efficiency and creating more heat or lowering the boost a bit but running a slightly higher cr?
Any imput would be helpful.

Go with 9.5:1 pistons. It will allow you to run a bit less boost before maxing the turbo out and get you to your goals easier.
I'll be going with the 9.5:1 pistons also when I build and will be going for 800+ whp.
