Some years Ago (2010!) I bought a whole series of items to convert my pre facelift 1987 Motronic 1.0 325 to the Motronic 1.3 as per this wiki link

https://www.e30zone.net/e30wiki/index.p ... tronic_1.3

Long story, but never got around to doing so and the car is sadly long gone. These items were all purchase from members here as used and working. From memory I have

ECU
updated pulley
Oil sensor
Ht leads with extra wire
Eninge wiring harness
CPS bracket and sensor
Updated injector loom and injectors
Speed ref sensor

Looks like I paid around £150 for these back in the day. If there's any interest here I can take some photos and box up and ship to any buyer. (based near Cambridge if you'd rather collect)

Complete wiring loom removed from a 1990 e30 325i SE includes : Engine loom, door looms, fuse box, relays etc etc. Car spec included trip computer, headlamp wipers, check control module, full electric windows, sunroof. This quite heavy all together so might best suit collection (greater Cambridge area)
