    M52B28 - E39 vs E36

    Hi All,


    Wondering if there are any differences between a 1998 M52B28 (not TU) out of an E39 vs a 1996 M52B28 out of an E36.

    To my knowledge the exhaust manifolds are different, the E39 motor has the FPR on the fuel rail, and the motor mount arms are different.

    Anything other differences i'm missing?


    Thanks!

    Be weary of the 1998 models as that's when the m52tu came out - which is in essence an m54 minus the DBW throttle (dual VANOS, updated head/block cooling route, m54 style intake etc). Up to 1997 the m52's are the same for the most part - aside fromm bolt-ons for chassis fitment.

    FPR is small potatoes for a swap as there's many work-arounds such as using a late e36 fuel filter with built in regulator, use an OBD1 e36 fuel rail etc.
