As I understand it, the 230hp N52 in the 128i (and 328i) is essentially the same engine that produced 215hp in the E90 325i and 255hp in the E90 330i. apparently it's simply a software change that is responsible for the changes in horsepower.
Anyone know of aftermarket options for getting more power out of the N52 in the 128i?

I remember seeing a "chip" over at e90post.com for the 325i that gave it nearly 330i power. I would imagine there is one for the 328 to get it to at least 245 hp, then intake and exhaust should get you to about 260hp. But that's about it. The engine reaches it's peak hp at 6600 rpm I believe so not much use in a raised rev limiter.
But if your going to spend around 2k for all those things, you'd be much better off buying the 135i. Have you driven a 335i? Go drive one. I've have mine for 8months now. It's a beast. And, it's getting great track time's, right there with the e46 m3 and rs4. The oner with better brakes, lighter, etc. will be great. Plus you get the m-springs.
