dct transplant

[VICN5FOUR]

Hey all

I've got an 08 135i auto and I want to make it a dct

this should IN THEORY be easy as the engine supports dct natively (335i has n54 ) and the n55 135i have dct in the same e82 chassis

any tips on where to start, just want the faster shifting and launch control

The 335i dct swap threads would be the most appropriate place to start.
Other forums have lots of good info

Good luck mate !

Talk to Tom at Brintech. He's your man for the wiring and coding required.
You cant just stuff a DCT behind an 8-bolt crank as they all go behind a 6-bolt.
But MFactory have a flywheel that'll let you do it.

Here is a thread on another forum;

you can get a 8 bolt dct factory flywheel but very expensive and only new
