Here's my problem I am talking between two guys the first runs a machine shop and said I need to do pistions, rings, rods and so on, if I didnt I would blow somthing up. The next guy runs a speed shop but does a lot of turbos, he said if I put a better headgasket in and do injectors I will be fine a 12PSI.

 

mmmm i dont know all stock i really wouldnt go over 8 to tell u the truth but thats my opinion. just to let u know mine blew with 8 psi t3t4 drag turbo kit. but what happened was the aem fuel regualator diaphram blew

 

i would feel comfortable taking a stock B16A to 10psi for a daily driver. it could probably do more but i wouldnt want to drive it. just tune it carefully.
