    The head is coming off tomorrow...

    What do you guys use to get the head clean and get the gasket off? I dont want to scrape the head using a razor because it will mess up the surface.

    anyone have any idea on these 2 sounds...

    Yes rod knock and engine knock sounds are similar, in fact the computer will read rod knock as engine knock and retard the timing

    this is the wierdest thing

    "PorterzSupra, how are you monitoring timing advance on a stock ECU? Knock displays don't tell you the advance, only if it's knocking or not (and even then not all that good)." My knock meter does not only display knock, it's a meter so it will display any pre knock sounds or if there is no...

    89T mbc and exhaust

    well.. stock is 230 hp, im guessing its only a catback exhaust so maybe +10-15 hp? stock boost is about 5.5 - 7.5 so the extra few pounds maybe give u + 25 hp? id say about 250-260 ruffly at the motor. Gotta also figure it milage, motor wear/age and state of tune.

    No, the ECU is not retarding on regular gas with 6-10 PSI. It should run fine on reg with stock to slighty over stock boost leveles with that compression. I am running a T66 on a high compression NA block and the ECU is not retarding yet on super!! I even have a knock meter!! Maybe if it was a...
