musccoo 82 Report post Posted September 5 (edited) Wondering if anyone has done a manual swap to a GS6-53DZ in the 335i. Obviously first thing is hunting down the swap parts but otherwise mechanically it looks more or less like a standard swap, just wondering about the electrics side of things with CAN...if it will all end up working...cruise control etc. Thinking about the ultimate family wagon.. On that note did any manual e91 335i's ever come into the country? Edited September 5 by musccoo Quote Share this post Link to post Share on other sites
Harper 551 Report post Posted September 5 Yes all the computer side can be made to work pretty easily, cruise control, reverse mirror tilt etc. Bit of a learning curve if you're not familiar with the software required to do it though. Quote Share this post Link to post Share on other sites
exextatic 118 Report post Posted September 5 GS6-53DZ is for N57 (diesel) vehicles - you'll want a GS6-53BZ, though a GS6-45BZ (N55) can be made to work. Quote Share this post Link to post Share on other sites

Pretty bulletproof gearbox. https://www.realoem.com/bmw/enUS/showparts?id=VB73-USA-06-2006-E90-BMW-335i&diagId=23_0926 Edited September 5 by Harper Quote Share this post Link to post Share on other sites

If trying to use a DZ, be sure to know it's coming from an N54-powered car; the bell housing will be wrong if coming from an N57 vehicle. 3 Quote Share this post Link to post Share on other sites
musccoo 82 Report post Posted September 5 Yeah it's a little confusing online. Is the bell housing different from a m135? Wouldn't have thought so.. Good to know electrics can be done, would be new (compared to old school stuff I've done before) but I'm an IT nerd so understand most of that stuff Quote Share this post Link to post Share on other sites
Driftit 2086 Report post Posted September 5 If you are doing it yourself find the gear in the US. You may need to join the East/West Coast BMW parts pages. I was seeing manual swaps or whole cars being stripped every other day over there. Though the boxes have become popular for LS swaps. Quote Share this post Link to post Share on other sites

The wikipedia disagrees with realoem as well. Would be strange for the M3 to get the BZ while the 335i gets DZ when the torque figure is the same.

The 45BZ used in S55 (F8x) applications is different (longer bellhousing due to different flywheel setup). 2 Quote Share this post Link to post Share on other sites
elias 255 Report post Posted September 7 (edited) If you have any questions feel free to pm me. I have recently manual swapped my 135i, I used a gs6-53bz box out of a factory manual 135i. It’s really not too hard at all. works like a factory manual cad, cruise control works, reverse lights, mirror dips when put into reverse etc. Edited September 7 by elias 1 Quote Share this post Link to post Share on other sites
