    Ok well I got a 88 celica st with the 3sfe but I'm putting in a 3sgte 2gn.
    im questions are?

    1)the 3sgte is from a mr2 so I know the Trany won't fit, so can I use the one from the 3sfi?

    2) are the hardnesses the same or not ( 3sfe/3sgte )

    3)are the motor mounts the same or do I have to make new ones ?



    i just want to know before I do it.

    somebody correct me if im wrong but....

    1)trans from mr2 should work. the linkange will need to be turned aroud

    2)harnes will be different. youll need the harness, ecu, afm, ect. so all the gte electronics.

    3)not sure on mounts... id imagine you could make hybrid mounts if you had both sets of mounts....pretty sure there would be a way to do it without fabricating mounts if thats the question.

    ...no experience with it.....

    Your old 3sfe tranny will definitely work with a 3sgte engine, all the original
    mounts will work. 3 tranny mounts and 1 engine mount hold the engine/tranny
    in the engine bay.

    I'm not sure if the mr2 tranny has the mounts in the proper positions.

    You need to check the flywheel on the 3sgte engine if its not the
    same size as the 3sfe flywheel then you will need to use the old 3sfe
    flywheel/clutch on the new 3sgte engine.

    You will need to use the 3sgte engine harness, so make sure the new
    engine comes with all the sensors that connect to the engine harness.

    You'll probably have to cut a hole in your hood if you get the original
    TMIC (top mounted inter cooler) with the engine or you'll have to buy
    an FMIC (front mounted inter cooler) and associated piping and clamps

    Definitely!
    Btw, I used my old tranny mounts on my MR2 tranny, they bolted right up, no mods needed there.

    1)Was is a FMIC ? -is it like MAF?

    2)So should I use my 3sfe tranny or get a mr2 tranny ?

    3)Just the gas pump not the tank right ?

    FMIC is a front mount intercooler.

    the 3sfe tranny would not last long. if you're lucky you can buy a toyota solara v6 mt transmission. it's the same as a mr2 transmission, but the linkages are already set up for FWD

    gas pump? do you mean the fuel pump? the thing that moves fuel from the gas tank to the engine? you should upgrade to a higher flow pump. maybe a walbro 255lph?
