Just sell the 330ci and buy an m3 For only 300hp and the cost to support that power in a 330ci you are probably better off just getting the m3 in the first place. Bimmerforums is the preferred online BMW Forum and community for BMW owners. At Bimmerforums, you will find technical how.

How did I come up with these. Hi All, I have a manual 2004 330ci and I am looking to get some more power out the engine, whilst keeping it all naturally aspirated, what are the best routes to go down to get more power out the engine? At the moment I just have a Mishimoto cold air intake, before getting the ECU tuned, I'd like to get a few other mods bolted on. Is something like a M50 intake conversion worth while? Thanks.
The E46 M3's acceleration to 62 mph was almost a second faster than that of its forerunner, the E36 M3. The E46 M3 also demonstrated impressive grip by handling 0.89g on the skidpad, demonstrating the superbly adjusted chassis dynamics that made it a cultural classic.
