does it mate to an m10?....the euro dogleg 5 spd from 323?


Recommended Posts

motor and the bolt pattern is different...

Same reason you have to use an E30 5 speed if you put an M20 into a 2002.

Nice thought, though.




I did some qwik searches as well...make sense?..here ya go:

245/10 c/r is for m10

245/11 c/r is for m20..

and of course 245/5 is the more popular 5 spd od used in w/ our m10s.

(oh btw..one never knows... as we use a getrag 260 from an m20 mated to an s50 engine that normally uses a zf!..in an e30 swapped car.)

As others say m20 box has different bellhousing bolt pattern to m10.

I have heard that m20 dogleg boxes have been mated with front part of m10 box. Which one, I don't know. Anyway that's because m10 dogleg boxes are more desired and rarer. This requires a gearbox specialist and some machining but it's possible as far as I now.

this may be the way to make it work w/ an m10......not my idea, but someone that says he knows.

"I've been told that you can remove the front case/bellhousing part and replace it with a 245/5 OD case/bell housing giving you a 245/10 CR tranny that fits behind the M10. Always someone looking for one of those. "

Bill- are you sure the 323 trans didn't have a removable housing?

There IS a combination that works... Terry Forland has been

doing it for the local vintage guys, but I forget what he's using now.


I only know for sure about the overdrive 5 speeds, not close-ratio trans.

I have a E21 323 OD 5 speed and it does NOT have a removable bell housing.

I've heard that you can buy the front case for an M20 5 speed and swap it to an M10 5 speed.

One other obscure possibility is that you could get a 1982 E28 528e bell housing and use that with an E30 M3 Getrag 265 close ratio box. Of course this requires transmission tunnel surgery, etc. .......

Yes- it can be done. I just had this done by Dave at aardvark and it involved removing the bell housing and replacing it with a housing from an overdrive unit. Some simple machining is required and then there is the while your in there factor if the thing has some miles on it. Call Dave.
