    Alright people, after realising that the rebuid i'm currently undertaking maybe a waste of timew does anyone know if a1992 non vanos M50 2.5 complete engine will work with the wiring loom in my 1996 328 M52 with single vanos.

    Basically can i just fit this engine and forget about the vanos wiring, or will the ECU have a fit and not work???

    Cheers

    morning mate
    am sure the 328 gearbox is different and not sure if it fits onto the back of the 325 as the flywheel and clutch is bigger and you may have issues with the starter motor, but no a good note the engine will work with just its ecu swapped, am sure someone else will be able to confirm the gearbox issues mate

    Genuine question.

    Why are you considering this project?

    It doesnt make sense to me

    because my 2.8 lump is pretty sick and although i've started rebuilding it ive been advised against it and my local scrap yard has a complete 325, which i'm guessing was span side ways into a kerb, with an engine and box in it. he's offered it at a good price so i'm just weighing up my options. i also have a v8 kit car so the BMW is only my daily runner really

    as long as u use the 2.5 engine loom and ecu u wont have a problem the 2.8 fly wheel is dual mass the 2.5 is single mass so i would be using the 2.5 one with 2.5 clutch and starter the 2.8 box will bolt up n work ok if u use the 2.5 box i think u will need to mod the 2.8 prop as their slightly different lenghts
    probably get away with loosening the big center nut and pulling it out abit

    prop lenghts:
    318is L=1564MM
    316i 1.9 L=1544MM
    320i m50 L=1541MM
    320i m52 L=1541MM
    323i L=1512MM
    325i L=1512MM
    328i L=1492MM
    m3 L=1367MM

    can you confirm this is the case please mate as my one has no nut and just slides on the shalf also you can only move the prop forward as the rear is fixed by the bearing mounts

    defo has a big hex nut ive just put a 2.8 gearbox in my compact and used the front of a 2.8 on the back of the 1.9 and i took apart a 2.3 auto prop before i got the 2.8 one to see if that would go all of them had the nut and i think it had a seal or fibre washer or something aswell too hold tight can check that
    if u need to get 1 ive got 1 laying around
