What's your c/r? If it's not much lower than stock, then something around 18 PSI, I believe.

haha are you joking? B18b's usually make around 230-250whp on that amount of boost depending on the turbo. They can make over 400whp on pump gas.

And you spell "door" only halfway to sound cool. It's not that we don't appreciate your opinion, we just think you're stupid.

Did you read any other posts yet?

yes

probably 16-19 PSI

only 93 Octane, but you need to have a pretty careful tune.
