    Hi

    ive just finished my engine conversion, 1996 318i - 325i m50b25 nv

    while i was at it i fitted lwt flywheel and clutch kit, cai, smt6 for custom tuning, throttle coolant bypass, gutted the stock 325i cats and fitted a scorpion back box..

    Basically i have got everything running as it should be with no faults whatsoever, idle is almost perfect, no flat spots.

    However.... After 2 months of driving it, im starting to get the urge for a bit more power..

    So my question is what modification shall i do next?

    Im thinking either cams or bbtb?

    Cams however are rather expensive, im looking around a grand for a set of shrick cams, as this is a non vanos engine.

    Throttle bodies are available from around £250 upwards..


    Pros and cons of either would be appreciated.. Or any other ideas for more power....?

    Thanks!

    I have read there is some trick with the non vanos motor where you buy only one aftermarket cam for the inlet side then swap the old inlet cam over to the exhaust side
    the old exhaust cam is binned as it is the least agressive (less lift and duration)

    that way your only buying one expensive cam

    If your interested I will try to dig up this info

    Do you mean a single bbtb, or 6 individual bodies?

    hi yes ive looked into that idea myself, however im not too clued up on how well it will work, what sort of power increase can i expect as opposed to using 2 aggressive schrick cams?

    From what I can remember about the NV cam swap it's to move the intake cam to the exhaust side and buy a schrick cam for the inlet side. Only works on NV engines.
