First of all, i was a little unsure in which category to post this, so moderators, be free to move to a better suiting category if you feel like it.
Some background....
I've been building a E36 Coupe with M50 turbo for years now, and the last big upgrade/modification i did on it, was putting in a DCT transmission from a E89 Z4 35is in last autumn. Although i didn't have time to test it for more than a couple hundred miles before winter, it was such a positive experience, i started another project with a DCT in the winter and hopefully will have it at least running and shifting in 2020.
So, long story short. It's a hellrot E36 318ti with some minor options like M-Sport package, nothing fancy. The car was my girlfriends old daily driver, but it was so badly rusted she upgraded to a E87 1er instead. I had a burning desire to do something "new", and i thought it would be a interesting idea to couple a diesel with the DCT, and all this in a "lightweight" car (yes, we all know the compact isn't in fact that light). The car has been progressing a little at the time from the beginning of the year, and at the moment almost everything is ready for the engine to be lifted in.
Engine/transmission:
Goals for the engine are nothing special for now, just the usual 400hp/800Nm, as the DCT is what inspires me the most, and also takes most of the time.
Chassis:
E28 typ210 differential case with E46 M3 LSD and diff rear cover
E46 M3 MK60 ABS (better wheel speed signal for the DCT)
Reinforced trailing arms with E32 hubs mounted for custom driveshafts
Body will be just some 3pc 17" AC Schnitzer wheels and a huge rear wing to begin with, it's the technical things that are more interesting for me.
Some pics...
What it started from:
Test fitted the whole package first, fitted nicely.
Had a couple of flywheels made, 8kg for the diesel, 6kg for an M50.
What 250k (miles) of EGR does to a diesel engine and some results of sodablasting it away.
Will also fit Fxx-series paddles on the OEM M-Tech steering wheel. They mount nicely with an adapter i designed and 3D-printed. I have these already in my other car with the DCT, and it's a proven recipe which works nicely.
On the F-series DCT software side i've spent countless hours of decoding the messages in the bus, and also built a little test bench to be able to simulate things.
I also have a little logger/configuration utility constantly evolving as i go further. Made it much easier to follow up on things and changes. It records and spits out .CSV-logs.

Engine/transmission:
- M57N (iron block) with 30d pistons (completely overhauled with new gaskets, bearings and piston rings)
- M57N head with grinded cams and stiffer valve springs
- M57N2 335d stock turbochargers (will go hybrid in the future)
- M57N R90 pump
- M57N 30d injectors (will go 535d injectors in the future)
- GS7D36SG from F82 M4, stock
