yo.
i just finished a B16A swap into my 2000 EX so ur in luck. go find the Skunk2 OBD-1 to OBD-2 conversion harness, that'll help alot. you'll need to modify your center console to fit the manual trans, if you had an auto to being w/ (i did). you'll need a bracket that goes under the center console to hold the back end of the shift linkage, i found mine at a junk yard, it's just a piece of rubber that doesnt even move... you'll need modified radiator hoses, cuz they will be of diff length. I had to make a new engine mount for the back of the engine, but you could always order yours from a company like Hasport. my trans-axles came with my purchase, and i didnt get a front clip. umm aside from that, it's fairly simple. you might have to do some research on connecting the map sensor, i had to get an external one that's just dangling for the time being. that's about it. any questions, feel free.
I ended up putting a B16A from a 95 Civic CRX SiR, a hydrolic tranny, lsd (u better get one, they help mucho!) in mine...
o ya, get a short shift while u've got it all apart. your going to find the distance to shift is akward... unless it was only for me.....but hey, short shifts are cheap and u'll like it! haha
