as the topic says, will a 1990 crx si manual tranny work on a 1990 crx dx with the stock d15b motor?

 

yes as long as both are stick/thread

 

yes. itll work fine in your cr/x.

 

i probably should have added that it will also be an auto2man conversion at the same time. and i have seen the write up by rywire.

also, would i be able to use the stock axles from the dx, or would i have to swap out. i know about all the parts i need; i.e pedals, man. ecu, cable shift assembly, etc.

 

Your stock DX axles will work fine.

Si tranny/your stock axles will work fine

just dont forget to install the clutch pedal

 

thanks for the info guys. one more question. do i use the flywheel and clutch package from the dx or the one for the si?

kewl, thanks. as for the throwout bearing, the one that comes in the clutch kit for a 90 dx sense that what i will buy it for would be fine to use as well as the clutch, flywheel, and pressure plate.

just want to double check my facts before i try to install everything. thats how i ran into probs with the booster/master cyclinder i did. did not double check my info. caused me to wait a week for a brake line for the master cylinder to the prop vavle cause i used a 1" m.c

 

'89-'91 flywheel/clutches are the same and '92-'00 flywheel/clutches are the same, but '89-'00 are not the same. The difference is that the '92-'00 flywheels and pressure plates have a larger diameter than the '89-'91. That said, there's absolutely no problems with using a '92-'00 setup with an '89-'91 transmission or vice versa. The throw out bearings are different though and not interchangable. You have to use the bearing for the transmission.

edit:
When I say that '89-'00 aren't the same, what I mean is that you can't use an '89 flywheel with a '97 clutch and pressure plate. '89-'91 is the same and '92-'00 is the same but '89-'91 and '92-'00 are different from each other. You can use which ever you want, the '89-'91 has less rotational mass and the '92-'00 has a larger friction surface. Hopefully that makes it a little more clear.

thanks for the info. makes life so much easier

Yep. I just went outside to double check. I still have the stock flywheel and clutch/pressure plate that came off of my A6 and a spare Z6 block with the flywheel still intact. No matter which way I turn the A6 pressure plate it's too small to fit. I can try to get some pictures tomorrow if you'd like.

88-89 Si all have the same flywheel and use a 200mm diameter clutch - 90-00 D-series all have the same flywheel (as far as clutch is concerned) and use a 212mm diameter clutch - 88-89 pressure plate will not bolt to 90-00 flywheel and 90-00 clutch will not bolt to 88-89 flywheel - if you are buying a complete clutch kit and your car is 88-91 with 89-91 cable transmission, you need 90-91 clutch kit - 92-00 clutch kits for the hydraulic transmissions use a different throwout bearing - just remember 88 transmissions are different

this is 100% correct expect 88-89's don't use the same clutch, '88's are 190mm, only '89's use the 200mm disc

 

88 = 200.
89-91 = 212.

I think, lol.

 

'88 = Different number of input shaft splines..

Perhaps the CX has a smaller diameter flywheel. But there's no way in hell this pressure plate is fitting on this flywheel. It's not that the holes don't line up, because they do, it's that the plate itself doesn't have a large enough diameter.

I haven't been able to get those pictures yet.

Dude, it's not confusing at all. Use whatever '89-'00 D16 flywheel you want and buy the matching clutch kit for it. Problem solved.
