  • Jason, or anyone! External Wastegate pictures

    Wastegate is currently removed and just sitting on the flange. I did this because when i originally reassembled the engine, I never took any time to properly finish the inside of the pipes where they are welded together.

    Whats not pictures is the heat shield that I made to protect the valve cover gasket and powdercoat from the heat off the wastegate.

    Gate is a HKS 40MM with a 14.7psi spring. External dump currently however im thinking of possibly making it dump back into the exhaust when I reinstall the engine again. Not sure if it clears the factory intake manifold as I'm using a custom manifold with forward facing throttlebody.

    ""You gota watch out in this weather. Its when them white boys with their turbos come out to play" Mr. Rimpson - UTI Instructor, refering to a slightly damp 50 degree day.

    Pics of mine. It dumps straight down. Im sure I could use it with the AC lines if I bend them a little bit and heat wrap them. It's a 38mm (Tial).

    My old setup; what a pain in the ass when one of the bolts tore out of the manifold; always leaked.

    I later turned the wastegate around in the first three pics so that the dump tube bolts on behind the manifold.
