Ok so Im building a d16z6 and using eagle forged rods and using forged nippon zc pistons netting 12.05:1 compression ratio. My question is it possible to put 15 psi from a 50 trim t3/t4 to it and if so what else will i need to do?

Not saying it couldn't be done but I don't think it's going to be worth it as a street driven car. Tune will be absolutely critical and you'll bef need high octane race gas. I'd use stock CR pistons or something closer to stock. 12.05:1 is going to be trouble with that kind of boost.

Itll be a weekend toy with little streeting. Im having DK Goodrich tune it. Car is gonna be raced alot on drag and roadcourses.

Thanks Teal. Would 10:1 be too high?

I've heard of 10:1 with a small turbo/less boost being streetable.
It really depends on what your tuner can do for you. They will be able to give you a good idea of the compression while keeping things safe. Also letting you know what octane fuel you'll be needing.
Keep us updated on this build

Will do Teal thanks again. This site has been huge help.

Little late on this but I just read a thread on H-T of a Gsr with off the shelf pistons at 13.5:1 that is also boosted. Lasted over 30 dyno pulls. My current setup is going to be 10.0:1 as well. E85 at this compression on boost would really help and greatly reduce the chance of detonation, it's not a must but I'd personally would recommend it.

You arent too late at all. My plan has changed. Im not for sure whats going in my hatch yet
