My friend was running 8psi on a civic(it had the type r motor and the garret t3/t4) and he F**KED it up hard core. Honestly unless you get internals just run 5psi. What I'm going to do is swap my motor for a GSR get internals and boost as much as I want(SAFE), and just keep my Type R motor. I wouldn't want to mess up a Type R motor just because is so amazing...listen to my advice...PEACE
Proper tuning will allow 300+ whp to be made with stock internals and that is a lot more than 5 psi. Your friend's motor blew up because it was probably a half-assed, hacked together fuel management system consisting of one of the following: AFC hack, FMU/Missing link, or some basemap made by some guy that has never even seen pictures of the car, let alone had time to dyno tune it for proper fueling and ignition curves.
The compression ratio is so minimally different between the GSR and Type R motor, so why would you boost a lot more on an almost equally high compression motor?
And we all know that 5 psi on a Greddy turbo is not going to be the same (powerwise) than 5 psi on a T3/T4 who knows what trim your friend had.
Your post just makes no sense and proves that you really don't know much about Honda motors or turbocharging in general.
