Hi i'm new to bmw after having vauxhalls all my life, Hense the username,(i left it like that as i'm still a member on mig, and its easier to remember)
Any way my dad had 4 bm's during his time, and i finally decided i wanted the same! So i bit the bullet, threw caution to the wind and went from nowing everything about vauxhalls, to nothing about bm's, apert from the reputation, So i was very nervous when i parted with some cash for my 2000 reg 323ci, i did want a 328, or a 325 but the price seemed right. and so did all the extras it has.
So this leeds me to my original question.... what makes the 325 20+bhp more than the 323 when they are both 2.5's??
And what is the best mods for adding a little bit of hp? not the chips that quote 10-15 bhp, but in real terms give 5-6! you get the idea, any addvice please, thanks Mark.
