CSL Gearbox modification from 4 speed to 5 speed, what's required?

[James Poulter]

Hi all,

What's required to convert a CSL to 5 speed?

I already have a Getrag 265 gearbox from a E30 M3 that I rebuilt a few years ago, can this be used?

I guess there is probably a previous thread about this somewhere.

Many thanks

James

Yes lots of threads in the search function.

The m3 output flange is longer. (279)
Swap it for the 4 speed output flange (061).
