There has been much discusion about this infamous swap.
I, among others on this site are giving this a shot.
Yes, it's been done to nauseum over in the U.K...but less here in North America
Lets start with the basics.
Before you start thinking "hey, I know of a M60b40 engine for cheap" let it be known, that your fancy V8 engine is likely one of the less expensive parts of the project.
take your time, and read this website-->
finished reading that?
move on to this-->
familiarize yourself with this website--> http://www.300mm.de/
specifically the "TYPE 5" section--> http://www.300mm.de/typ5/typ5.html
still gung-ho?
awesome.
I'll focus on *my swap* specifically, which my goal is to have a functioning m60b40 working and road ready in my e30, using the most basic methods. There are MANY variables to this...6spd, obd2, EWS etc etc
I'm cross posting information offered by Garey (bmwmech1) as he seems to to have harnessed this quite well, and has been a wealth of information for my project aswell. Special thanks also goes out to Noid over on Maxbimmer.
Not knocking the 6 cylinder swap as it's straightforward and well documented and there are plenty of bad-ass M/S5x swapped cars running around with a ton more HP than an M6x car will make. That being said, I agree that it's been done and done well, whereas the V8 swaps are not as common, so the "wow" factor is a little higher. I think most of the larger hurdles have been covered, so lets talk about the M6x swap in a little more detail...
Basic Parts collection
1. Transmission- either E34 530i 5 speed or E34, E39 or E39 M5 6 speed. Both require different clutch/flywheels, but either will work, effort varies. Mounts for 5 speed are stock E30, 6 speed has to be made.
2. Motor Mounts- can be bought (300mm.de) or made, I made mine, pretty simple to do.
3. Cooling- E36M3 or Z3M radiator drops in, Z3M is the preference, since it's 3 row.
4. Exhaust- E38, E39 or X5 4.4 manifolds are necessary to start with, the rest has to be custom made... enough said
5. Braking- Easiest to source an E34 V8 brake setup and retrofit.
6. Electrics- 404 DME from an E34 or E32 V8 car, harness can be made for C101 connector pretty easily.
7. Driveshaft- E30 M3, E36 328i, early E36 M3 4 bolt are bolt in for the 5 speed, 6 speed is more work, due to longer length of trans.

ECU/DME
As far as the wiring goes, you need the engine harness and 404 DME from a manual V8 OBDI car, preferably the car the engine came from, if it's OBDI. You need to make a "connector" harness, just like the ones Rogue sells for the M5x swaps, for the C101 connector in the car to the engine harness connector, assuming your car has a C101 connector. Since these E30s and E34s were from the same "era", most of the wiring is similar, as far as what is in each loom, diameters and in some cases, even colors. I makes it simpler, but not plug and play.
ECU/DME con't
The 0 261 200 404 Motronic m3.3 ECU should be used because it lacks EWS, and thus is much less of a headache then other m60 ecu's.
As far as the tachometer is concerned, either a 4 cylinder cluster needs to be used or you can use a 6 cylinder cluster and take the chip/white plug from the front of the cluster of a 4 cylinder cluster and exchange it into the 6 cylinder cluster. Then you need to half the signal from pin 47 from the ECU (anywhere along the wire path to the cluster regardless if using a 4 cylinder or 6 cylinder cluster).
Brake Booster relocate
The most challenging part one could argue is the brake booster, I find the easiest way is to just use a brake booster from a e32/e34, and to mount it behind the left headlight (via welding) and extend the push rod.


Exhaust Manifolds/headers
For the exhaust mani./headers part numbers 11627500483 and 11627500484 should be used from an x5. Everything after that, is custom.
Now keep in mind, this is still a very basic guideline as to what to expect.
this is more of a "what to collect" before you start the swap.
Happy hunting!
