Just to confirm, you added N54 headers and intake to your N52 for more power? Is the N54 manifold the same as the 3 stage manifold from 330i?
May have to pass this information along to my 128i friends.

While I haven't put the car on a dyno, I would estimate a minimum 35hp increase over factory. On track it lives between 5k and 7.5k RPM, being near the top of that range multiple times per lap, every lap. This results in high oil consumption, but overfilling before an event and topping up every other session has proven effective thus far. My concerns over longevity are easing with time and on the street it consumes 0 oil, so at least I have that benchmark going for me. My top speed on the back straight at VIR was 134.6MPH at ~40degrees.
