i've done this w/ the help of two knowledgable friends on my 98civic dx.. Not worth it unless u blow the auto-tranny, even then it was a PITA. Acutally winds up costing u **** load if you buy all new parts and hard to find used especially since our cars are new.
Some stuff u need. (depending on what car)
Clutch master cylinder,
Clutch (pick a stage)
Tranny + fluid
Tranny supports(possibly different)
Motor supports (possibly different as well)
Reverse needs to be wired for ur reverse lights
manual console, (possibly different)
Did i forget anything ?
true story btw: I had a 1997 Integra in 1999. I got it automatic cos I'd no idea how to drive manual. So I get this job right? Thing is...company car I'm issued is a manual ford pickup truck! So I had my mgr teach me how to drive stick in 7 mins! No joke, it was that fast. I loved being in control of when gears are shifted and what not.
So I take my Integra to a shop in SouthGate, Ca plus $6500. The car was lenghtened by 4 in. to accomodate for the s2000 engine plus tranny. Car drove amazingly smooth. The guy told me he'd never done it before but cos he was in need of money, he took the job. He even loaned me a 95 civic hatchback cos it took him 5 weeks to finish the job. He did a very thorough job. it looked very proffesionally done. Where he "acquired" the s2000 motor & tranny, I don't know. But, since 1999 was the first production year for the s2000 here in the states(1995 for japan), I know it had low miles.
