m70 umbau nicht bmw

[transeurope]

Hello

I'm buying a m70 from a 94 e32. What do I certainly need to buy with it to let it run in a non bmw car?

I think I need:

Engine
3 ecu's and loom
2 lmm's and maybe also the airboxes
bellhousing of autobox (I wanna use a tremec t56 6 speed)
And also the device for the electric throttle? Is it located near the throttle pedal?

Anything else?

Cheers & thanx in advance. Sorry for the english but my "Deutsch" is even worse ;-)


ps Am I right this engine is still the m70 version with boostfriendly CR?

Yes, the throttle position sensor is located near the pedal.

I think, thats what you need.
Of course, all the other sensors too.
Cylinder identifictaion, engine speed signal, water temperature and air temperature (every sensor twice).
I would also use the original alternator and if needed, the air conditioning compressor and the power-steering pump.
Maybe also the oxygen sensors.

Part of the loom is a relay box which you should also use.

The electric throttle needs a bulb which is located in the speedometer of the E32.
But you can also use an external lamp. (About 2 watts)
The ecus need a speed signal which they get from the speedometer.
Actually it comes from the differntial (9 pulses per rotation) but the speedometer treats the signal.

There exists a BMW 6 gear box from the BMW 850 which fits to the M70.
(Right now, there are some new ones on ebay)

In which car you want to attach the M70?
And do you wanna turbo charge it?

Yes, you don´t need the speedo or dashboard.
Just a 2watt bulb.

What you realy need is the Speedsignal!
If you don´t have it you´ll only get half power and that is boring...

thanks, 2 watt is also new info for me.
2 watt bulb on which Pin/line/wire exactly?
 Steckerbelegung Kombi

[Grimmjar]

It is x502 pin 16 and 17.
I have both wires on the bulb.

It´s looking like that:

12volt Batt. ===> 7.5amp Fuse ===> 2Watt bulb ==> Both wires on x502 pin 16&17

Both wires go to EML and during the Test EML will connect them to 0 Volt/Ground/Chassis ...


(i´m writing too slow..... )

Thx. Where does the ecu gets its speedsignal? I thought you could change the ecu to "manual gearbox mode" and that then it was ok..

Ps I bought the engine and other parts. The vendor is now parting the e32 out and 'll let me now when I can pick up my new engine..

Greetz,

Speedsignal comes from the rear axle differential.
But there is a cheap way around this.

btw.: what rear axle do you have?

Seriously? It's in the link you posted!
