Just the m50 inlet and the engine should make 200-220bhp but slight drop in torque low down as the ECU isn't suited to the reduction in restriction of air.

M50 inlet, BBTB and a ECU re-map and it'll make a strong 230bhp and torque back all through the rev-range.

One or two other bits like cams etc and it'll make 240-260 depending on the engine.
