depends on what you want to do with it. (i.e. drag race, autox, street). i would recommend a b16 tranny for a drag type car for the shorter gear ratios and faster acceleration. but im sure there are a couple more knowlegable people on here who know alot more than me who could help you more
ill be going street with it someone else told me about a dc2 gsr trans. i wanna know everyone's opinion on what could help me out.
gsr trannys are good but a b16 has shorter ratios but its ultimately up to you you can always re-gear it for whatever you like as well.
like he said its all about what u will be using it for and how u drive. try to go to some local used car dealers and test drive vehicles with the trannys that ur looking at if possible and see what u like. this is not always possible though
