You claim you have done countless turbo's on imports. Boots it boost no matter if its a 4 cyl or an 8 cyl. Its all the same science.

Suck, bang, blow.....its all the same - 1 cylinder all the way up to 12 cylinder motors.

MOST imports I beleive use return style fuel systems correct? I am pretty sure (like brian stated) that the car you are working on is a return style fuel system. A good pump, tad bigger injector, and a regulator that has a 1:1 boost ratio will work. I am pretty sure its the same thing you would do on an import motor
