hondas par example into the 11s and boosting in the teens and near 20psi completely fine
the 7th gen celica 11.5?cr and boosted fine

you cant compare 11s hondas to his car. you are talking about cars that run nothing but race gas, and have better tuning then just a piggy back. as nice as the emanage is, its still FAR from a standalone.

as far as 7th gens go, their community has had a very hard time coming up with a reliable turbo kit for the GT-S or even the GT. most of their guys have to fully rebuild the motor to run any kind of boost.

trd94, the higher the compression, the harder of a time you'll have trying to combat knock on pump gas. even just 10psi, is still a fair bit of boost and can cause a good bit of detonation.

why are you even thinking about opening up the motor? did something go wrong?
