I just bought a 1986 325e that had a 2.7 in it.Guy swaped a 88 2.5 out of a 325is question is will the computer that is under the dash run the 2.5? Or will i have to run the 2.5 ecu?And will the factory harness work since the 2.5 ecu plugs right in the 86 2.7 harness?Any help would be appriciated.Mark
Ok ill change the just the ecu under the driver side dash.And see if that will work.Any idea how the headlights tie into the main harness? I got the car half way thru a swap guy got tired of messing with it so im trying to finish it.Thanks
only reason is that what you are asking about is a major project that I would reckon many DIY kind of guys would even attempt. I wouldn't and I have converted/swapped a 1974 2002 engine (automatic trans) into a 1976 2002 body (4 speed). That was not easy and these were 2002s, comparatively nothing electronic. I would say that, without looking into this in more detail,
is completely unfeasable financially, if even technically.....good luck though...keep us posted on this baby....cliff
The car bodys are in the same,The engines are pretty much the same from a 2.7 to a 2.5I mean the engine is a 88 model And the car is a 86 model not much diffrence.I have a complete harnesss,ecu,out of the donor car,I WOULDNT SAY ITS UNFEASABLE.Im just wondering if i can run the 2.5 engine threw the 2.7 engine harness while just pluging the '88 2.5 ecu into the 2.7 harness?Thats the only thing i need to know.Anybody done this swap? That can help?
