ok, but how can you tell if the turbo is on the way out, on my 306, my tubro gauge had oil coming up the pipe but yet my turbo was new, i can get a hpi i check on it from work so i can find out some details about it, yeh true about modded cars, but then i know i have done it all my self, cus then the car feels like its yours rather then someone else done it all, and you just buy it, turbo timer, got one in my old car, but i havent got a clue how to wire it up any ideas?
