h22a is jdm and it is 10.6:1 and you are going to blow your motor cuz u have no idea about what u have....im sorry

But to run more boost u have to get a better fuel system and a way to manage it.....u can run up to 7-8 psi on a stock block with very good tuning and still you are taking a very big risk......unless u rebuild it would be best to keep it at 5 psi and also learn more about your car!
