    for the motor at the least rod bolts if you plan to exceed 500hp. If you want to run alot of boost forged rods and pistons ( lower compression )

    Built tranny cause that wont last long.

    I would do pre fab hot parts to save time unless you dont mind the truck being down............trick/nelson, TRT/sts

    do a blow off valve to save the compressor, doesnt have to be the most expensive or best out there if you have an automatic but dont be cheap either.

    Alot of people run the GT67 turbos, it all depends on how much power you want to make.

    As far as the waste gate goes that depends on location, size of turbo, A/R. The mounting flanges are different so if you plan on going with a big turbo and high hp a larger waste gate might be good to start with.

    You will need to do fuel system upgrades at the least a 255lph in tank and 42# injectors, but that all depends on how far you want to go. You could go with dual in tanks and 60# or 75# injectors. If you plan on going with alot of boost I would switch out the intake for a carb style with an elbow to evenly distribute the air. Its not the cheapest thing around, but its cheaper than getting a new motor.

    Also get a boost controler either manual or electronic

    You can get more info by contacting Nelsonperformance, TrickPerformance, or TRTurbo..
