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....?
