I gave it a shot with the N55 torque converter today and it looked like the bell housing didn't want to seat fully. The N55 converter is a bit longer than the 6L45 N52 converter and has different spline pattern. I'm thinking I'll try an N20 converter and see how it goes.
I have the Seems Legit driveshaft for the M3 DCT swap and CANTCU with an F82 M4 shifter, so the transmission cross bracket and torque converter are the last bits to figure out.
RealOEM shows the E89 z4 sdrive 28i had the 8HP45 and used the same rear mount bracket as the 128i. https://www.realoem.com/bmw/enUS/sho...diagId=22_0106
Didn't realize this until I got home today or would have attempted to bolt it up in the car. Can't get back to it until Tuesday, but will report back. |
Thanks for the answer
I’ve been looking for some more infos but I can’t find any.
The n20 converter mounting is different with the flex plate not being flat, and that may cause an issue apparently with the n52 flywheel.
I’d like to give it a shot however as that’s a daily driven I can’t screw it up, hence the reason I look up EVERYTHING to make sure I have no bad surprises under the car.
For now, I’ve seen that the transmission mounts are compatible, the ATC 300 looks compatible with the 8hp45x awd version (not 100% sure though) and the CANTCU offers a full compatibility.
The only thing I have to figure out is which TC should I get and how to make it work.
