    not really. lol
    maybe moving to a closer tranny from a dx or ex trim level car would help with passing acceleration

    The 90-91 EX transmission is cable. It has a 4.058 final drive, which is still quite a bit better than the DX hatch's 3.888 without being as short as the Si's 4.250. It has the same 1-5 gears as the hatch DX and Si. All the sedan transmission ratios are the same from 88-91, so if you're looking for an EX and can't find it- just get the DX or LX sedan transmissions.

    turbo charging an hf motor is really a waste of time dude.

    You'll get better results swapping in a ZC engine- then you can turbocharge that later if you want.
