    I did the same swap on my 94 LX and it didn't require anything new. I'll tell you what, I like the Si tranny's shorter gears a lot better, especially on my Z6.

    ok, lets play that game.
    -and a new throw out bearing.
    a new pilot bearing
    a new pressure plate (you said clutch, i assumed disc)
    and the correct alignment tool
    and about 2-3quarts of honda specific manual trans fluid (dont use engine oil, it can damage syncros)
    and a can of break clean to clean off the flywheel
    and a 32mm socket
    a huge breaker bar or an impact capable of about 500ft-lbs

    should i go on?

    no, you need nothing from the Si but the transmission. EVERYTHING from your DX will swap over. (axles, mount, linkage, reverse light wiring, clutch plate (assuming it's from the same year. the 88-89 disc has a smaller diameter input shaft than the 90-91. get a new clutch disc the same year as the Si transmission.)
