    Ive heard that the only difference between the dx and si tranny in 89-91 is 5th gear.
    Is it a longer or shorter gear?
    Im looking for the reason why 5th gear is different?

    i was looking at a flywheel and clutch from LSD.
    Not too much for plans for the car, but ya was thinking since it was out, why not. Gonna wait till the tranny i got is pulled, cause i dont know if the guy did anything too it.

    I figured thats all i can do with the tranny, probably get a cheap short shifter too.
    dunno what i'd do to engine since its sohc, rather have a zc dohc
    but if u got some suggestions, feel free to shoot.

    lol

    ya i think im gonna just have a tranny put in with a flywheel and clutch.
    save me a lot of money, car will be fast enough for me, got alot of compression. i can go down hills in 5th and the car slows down :huh:

    but i would drop a zc dohc in my bandit, blanco, run that with a light ass flywheel and clutch, and i will be set. I'd be doing that swap with my dad, since im not gonna dedicate myself to racing till i have a shop.

    blanco u should send me pics of ur car!
