I want more power. I drive a 318is (99), now it is OK but I would prefer more power. So, I enquired on engine upgrade to 328 but this is provin to be pretty immpossible. However tryin to sell ma car is also hard so i cant sell and buy another. However I was thinkin that would it all be possible to add modifications that won't effectively destroy my engine? I would like to take the power to the 200-220 bhp figure. What should I do to upgrade the performance and how should I do it? Also how much will I roughly be spending to achieve all this? Any advice is appreciated. May I also mention, I have always been led to beleive that modifying an engine will always make the engine prone to problems.
