What's up guys.

I'm thinking about getting another 335i and wanna do a single turbo build. I'd prefer to have an auto vs. manual. I've been reading up and some people are kinda skeptical about LVL10 which kinda makes me wanna do the dct route (if the power can hold, trying to hit over 700).

I have 2 questions:

Is the E9X M3 DCT different than the DCT in the 335is and will it fit in our cars?


Can I find an e9x M3 with a blown motor and put an N54 in there?

Thanks!

The only "hardware" I can recall that is literally different is the DCT output flang that connects to the M3's drive shaft which is different from the N54 DCT output flang.

Found this in another post, so I'm guessing they have the same transmission but different software.

Can anyone confirm on the N54 being put into an M3?

Same transmission and different software yes. I'd be very skeptical about a DCT trans holding 700whp though from an N54.

What i think to be true...
They are the same gearbox internally but the bell housing is different as is the output flange. You can compare photos on eBay.
I suppose if you were to blow one up you could use the internals ...
They use a different gearshifter or GWS and they use different software.

Same transmission with a different bell housing. Same transmission control unit with different software. DCT progress has been pretty big overseas with people putting down 700hp on stock clutches without slippage. You need a tuner that knows how to tune for DCT reliability though.
