Any D series would bolt up.. but you'd have to content with them being a cable tranny (which isnt such a big deal anymore). I'm 90% sure a ZC tranny would bolt up, but its a cable tranny. (like i said not such a big deal these days) ... maybe CRXer can verify the ZC fitament.

Even the USDM GS-R's have a pretty mild geared tranny.. the best thing you can do in that situation is:

(on a B swap w/gsr tranny)
keep 1-2 .. swap 3-4 with a ITR gears, and put an LS 5th in. .. you have a nice hybrid tranny with very good gearing 1-4 and 5th is so long your top speed is: ridiculous.
