Hey D forum, I have a 13:1 Compression built all motor. With a back yard transsmission built for turbo, the car is a highway beast. I got a Greddy SOHC turbo kit for real cheap 750, for alot of things not bad. with fuel pump, installed. Real real good deal so i took it. Installed it. At first the motor was loving the boost. was not detonating. My IACV valve is bad and everytime it gets warm it acts up crazy and messes up my car.
