328is_perf... you need proper tunning... that's worth at least a 1/4 of the price that you pay for a good, solid kit... I just ordered an AA supercharger kit for my z3 2.8 (97). It's being custom tunned by AA for the M50 manifold, M3 cams, headers and exhaust! Otherwise you'll end up putting in too much air and thus running lean which will blow up your engine. I ended up paying around 5K USD, though I could have bought an untunned vortech kit for 3,500 USD and spent a good 800 USD for software (AA) and another couple hundred on dyno time.

If you want to do things properly you need solid and reliable tunning. That's why the kits are so expensive in our situation. I believe the key phrase is "big power, reliablity, price - choose 2"

Best regards,
