[HOW TO] e46m3 6-speed your e30

[rThor432]

^^ I love that gearing..

Just adding a little info for those considering a 6-speed swap. Here's the speed/RPM calculations for an E46 M3 6MT (S6S 420G) with my tire size and differential. I can post other combinations if anyone needs, including substituting gear ratios for the ZF 6-speed. LMK.

ZF transmission, totally different setup then the GETRAG.

Ya I know, thats why I said 'zhp'. It was asked if the ZF could be used instead of the GETRAG so I posted a link showing it works with mostly stock parts.

The pilot bearing for the e46 trans is mounted in the flywheel, I believe. There is some sort of adapter for that that lets you use the e36 FW with the e46 trans.

not on the GETRAG just the ZF

I was thinking of doing the same thing. Use a E36 clutch and LTW flywheel but then just replace the friction disc with one from the E46 M3 6spd. Can anyone think of a reason why this wont work? The disc is the same size and thickness. So we should be ale to use this clutch/flywheel combination and also eliminate the E46 self adjusting clutch setup as well.

Yes, you can. Talk to my friend Jordan at Southbend Clutches. JordanMD88 is his SN on BFC.

Anyone have pictures of a trans brace that they had made? Just looking for ideas...

I thought you had one installed already once, I assumed you would already have known this.

Nah, as we discussed, a friend installed it. It didnt appear to have much adjustment left in it when I looked at it, but then again it was bolted up and the car had been driving fine, so I wasnt too nit-picky about it.
