do your research in these forums ;-)

'like i said in a previous thread... there's a hundred and ONE ways to extract HP, and answers are there for the taking if u will only put in the effort to find them

The fly wheel will not give you any more power. With the 318i you are limited in your options. You can do an engine swap or go with FI. If you go FI I would recommend the Downing Atlanta super charger. It will boost you up to somewhere around 200 hp (don't remember exact number). With that you would want to do some modifications to your ECU, CAI, maybe throttle boddies/fuel injectors and exhaust. And it will be expensive.

For LSD your options are limited. The 318i diffs are tough to replace. Your only real option would be if you have a manual, you can swap to the auto diff but your top speed will be around 88 mph at red line in 5th (if you can even find an auto lsd). I am not even sure if the 318 came with a lsd for either auto or manual. If you have an automatic you would have to find diff from somewhere else and last I checked most (new) were over 1k same for a manual.

i've the same problem as you. i've a 316i. and its so dead. i'm planning on chipping it, replacing the spark plugs and leads. and going from there. i have a full induction kit. wheither thats doing any thing. i've heard a 325i lsd will fit. so i'm told but i'm new a this game and am lookin for info too.

ive got 325i 1998 and it feels like it needs more power too. i was thinking of turbo charging since my parents' x5 has one and that really goes when u step on it
still looking for answers though; feel free to enlighten me on stuff
