ok well ive been drifting for about a year in my s13 i had a ka24de with single cam pistons so it was just a hig compression ka. then that car got stolen. so i bouth another one and tried going turbo but the turbo hit the brake master, so i got pissed and now im just putting a 2j in the 240. does any1 know how much boost i can run on a stock jdm 2j safely. the only mods are intake exhaust front mount and a walbro pump??when to the turbos actually shatter???
