e30 m3 transmission on m10 block

Help,

I have an e30 m3 dogleg and I want to fit it to my 2002.

I know it won't match straight up to the block cos I've tried, but can you split the box and place the rear castings of the m3 on an m10 5 speed OD front casting without any problems?

I know it won't fit into the front of the 4 speed 242 getrag casting as the selector shaft is too long and the casting hasn't got the cut out for the selector lock pin. But has the OD 245 got the same lock pin cut out and longer selector shaft?

I thought the M10 and S14 engine used the same block? at least the same bell housings?

Any help much appreciated!!

Regards

I thought that but the starter motor holes are a different pattern, the straight piece that fits just below the cylinder head is much longer and the flywheel and clutch stops it going high enough??

I was starting to think it must a m20 box but its definately dogleg and my m42 e30 has the same pattern??

Regards

Not sure what you have there. What is the Getrag model number on the transmission?

m10/s14, but it is not from an e30 m3. It is missing sensor mounts on the bell housing and the rear gear change mount is not the style use on e30s. Figuring out bolt patterns/fitment from the bad pics is beyond my capabilities.

Thanks anyway.

Is the M42 pattern the same as the M20 pattern then as it's just like that?
