    definitely need a custom tail shaft, depending of model of cressida might need the cross member, and u need a front sump 1jz so being a supra i think you will need to convert it to front sump, if your using the stock 1jz ecu look around on the internet for diagrams to go from 1jz to 7m to make all your accessories work, i think one thing that wont work is your fuel gauge, and a accelerator cable, and i think thats about it, suprisingly the stock 7m fuel pump will hold out, and hasnt missed a beat

    I thought 1GGTEs were close to straight bolt ins for Cressidas, unless its a different model im thinking of or im mistaken.

    On a serious note though, is it a manual or auto cressi? If auto you will need the pedal box master and piping to hook up with slave on the R154. Tail shaft might need changing, maybe. You will need different engine mounts. It wont bolt straight in. Sit to far back or something....cant remeber. My mate is doing the same conversion but with a VVTi 1JZ-GTE single turbo. Wiring shouldnt be to hard..look on the net. Yeah, intercooler piping. Exhaust. brakes???? Would change the fuel pump, not straightaway but i would change it.

    A mate is doing this conversion too.
    He started off with a 1JZ from a JZA70 but he had to buy cross member and mounts etc, so he sold the motor and bought a chaser front end to make things much easier.
