M57 powered LR Discovery

Peter4x4 · 01-04-2021, 05:19 PM

Hi all! I'm currently building a M57 powered Land-rover Discovery for off-road rallying. I know, it's not the car you guy's like, but I hope you like the engine... I am new to the BMW engines, so when I come to wire and plumb the M57 I will probably stumble up to some issues... Questions will follow... This is the project so far:

M57 with single mass flywheel conversion and gearbox adapter kit.

Fits like a glove...

The car... LR Discovery chassis (modified) and fiberglass body (except the doors)Pick-up conversion.

Nice. Looks like you picked a single turbo motor. I guess you found one for a good price.

Peter4x4 · 01-05-2021, 04:20 PM

Yes, single turbo. When you are alone in the Moroccan desert, things need to be as simple as possible...

Boyd122 · 01-05-2021, 10:04 PM

That's awesome!

Persian Whisperjet · 01-07-2021, 11:23 AM

Super cool. Great engines.

Here is my first question: Where can I find a complete pinout of the ECU? Some wires are cut by the previous owner and I can't figure it out without a schematic or wiring diagram. Especially the throttle pedal. This wiring loom is cut off, but I don't find a connection on the ECU side.

Mik325tds · 01-16-2021, 10:37 AM

I guess your best bet is to search online for an ISTA+ software packet. All schematics are included. It'll also help you to diagnose faults once you got it running.

Mik325tds · 01-16-2021, 10:56 AM

Here are a few to get you started. The accelerator pedal signals are the module A_FWG. If you have ISTA+ it's much more comfortable to zoom in and the links give you close-ups of connector view and install location of sensors etc.

I sent you a PM, but the throttle pedal is on X2414, the 40-pin connector. Pins 7/8/9 and 12/13/14 are ground/signal/supply for each half of the pedal, and they map to the pedal pins 1/4/5, 2/6/3 in that order.

Progress so far...

M-technik-3 · 03-02-2021, 04:27 PM

Interesting that it looks like the intake is inside the cabin. Cool build, I honestly like all cars and yes even electric ones as the technology becomes better they will too.

jacbo · 03-03-2021, 04:58 AM

Looks awesome so far. What car did the engine come out of?

Peter4x4 · 03-04-2021, 10:49 AM

BMW 330D touring 2001

Air intake is on the side. Inside would be to noisy!

Peter4x4 · 03-04-2021, 04:33 PM

Who has a solution for my next problem? The original alternator is way to big for our car. It weighs a tonne and we don't need the 150 Amps charging capacity. And, most of all... it doesn't fit between the motor and the frame rails...
Is there a bolt-on alternative from another car? About 70 Amps would be sufficient.
We can fabricate some brackets, but something bolt-on would be much nicer...
I'm sure there are some M57 guru's around here....

Most of the M57 folks here are US-based, and there's enough different between the US and EU-market cars that what might be good advice doesn't always carry over...

With that said, I don't think there will be a plug-and-play replacement because your alternator is probably interfaced with the DDE using BSD, a BMW-proprietary variation on a family of low-speed serial protocols. Happily things will run just fine without it, but you'll almost certainly have to fab up a bracket and fit some smaller alternator with an internal regulator.

I'm actually kind of interested in this myself, since whilst I have room for the full-sized unit, I don't actually need it either. But by the time all the belt routing etc. gets taken care of it'll be moderately complex...
