    Possibly a 4.3 FD. @PetefromtheStreets is great at transmission, he will chime in.

    Post a build thread!

    Thank you for the kind words man.


    What is the car being used for? Just a daily driver? Track car or drag racing?

    For a track car or a daily I'd stick with what you've got. Quicker acceleration

    Personally if you're only spinning 1st and second I'd leave it be. There are things you can do with the blower to lower boost in those gears if you prefer.

    Jaydee used a tial wastegate and welded it to the charge piping and used it to reduce boost to help with traction. This may be a more effective route for you to explore.
