Welcome to the BMW world!

Well you have -

Engine - 2,494 cc - 6cyl - DOHC - 24V
Power - 168bhp - 181lb·ft
Engine Type - M52B25
Zero to Sixty - 7.9sec
Top Speed - 144mph

For power increase you can aim for 190bhp easily - you will be wanting a 325i M50 Manifold Converstion - which can release up to 30bhp Approx

Get it Chipped or Re-mapped - up to 15bhp

For the engine change he means that the car insially had the Nikasil lined engine that did suffered from bore wear etc... and you have the Alusil lined engine which was BMW answer to the Nikasil fix in 1998 - BUT I only thought that this was only with the 328's - I may be wrong... but that is the only thing I can think of why...

If you want to check... Open the bonnet & stand looking into the engine bay from the passengers side, look straight down the side of the block and toward the rear and you should see it! If not you might have to hunt a bit harder for just the nobled bit (non-Alusil).....depends how dirty the engine is!

Nikasil Block :


Alusil Block :


Hope this helps....

EDIT: Sham you beat me to it...
