Hi everybody.

I’m sure this has been covered somewhere, but I can’t seem to find a definitive answer...

I’m picking up a 94 coupe with an automatic for my girlfriend to drive while her Subaru is out of commission. Eventually, in a few months when her Subaru is fixed, I’d like to put a manual in the car to suit my needs more.

I’ve got a 5 speed from a d16y7 1999 civic that I was hoping to use.

But here’s my real question: what other parts specifically can I use from my 1999 civic parts car on my 1994 manual swap? Pedals? Plumbing? Whatever?

I checked the interchangeability thread but that thing is so bloated- I couldn’t find much.

I’m pretty sure the pedals, clutch line, and clutch master cylinder are interchangeable.

Your ECU from the newer one won’t work in the older car without a bunch of rewiring. Plus there will be EVAP codes and SHO2S codes. The EVAP codes can be fixed with a bypass module, but you’d need to run wires for the SHO2S.

The T-bracket that goes from the transmission bellhousing to the subframe is probably going to be different, too.

thanks man.

so I should presume that getting a manual transmission ecu for a 94-95 would be the best way to go? Instead of using the auto ecu and trying to make it work. An ecu and some mounts are relatively cheap. Might want a new cluster too.

this is all good news!

I sure did think that. Yeah, those OBD1 ECU’s are a lot more hackable than the OBD2’s.

Also, it’s a good idea to replace the crankshaft rear seal while the engine is out.

Is the transmission to framerail mount the same on the auto and manual, or am I thinking B-series? Am I right about the T bracket?

I used Integra pedals in my EK without issues. Idk if they’re the same as the EG, but I’d think they’d work. The shifter boot might even fit.

Thanks guys! It’ll be a good long while before I do this, but I like to get my parts list far in advance.

thanks again!
