XDrive and Trans Swaps

D3Rich · 05-06-2022, 09:56 AM

I have a 2011 335d and it will be pushing more power than the zhp6 can handle. This will be an outlaw dragster. I’m considering a power glide trans. But wanted to weigh my options. I would really like to make it X-Drive and was considering trying to drop like an 6 or 7 series DTC with xdrive. Does anyone know what all is needed to be done to make this happen. Maybe 8-speed ZF 8HP70Z automatic (640d / 650i)
7-speed Getrag GS7-D36BG dual-clutch automatic (M6). Does anyone know what the highest torque rated x drive trans that’s put in a bmw and do these trannys bolt up?

Unless AWD is really important to you for getting off the line, you might want to check into aftermarket support for the 335d transmission in Ford flavors. I recall the 6 speed being basically the same as the Ford 6R80.

I recall an old timer here (banned long ago) from several years back using some of the Ford parts when he beefed up the 6HP26. Worth a look and I'm not a transmission builder but will add this to my skill set eventually.
