Bmw 323ci supercharger!!!?

Question

what do i need to do to my engine prior to fittin supercharger?

Answer 1

Nothing most supercharger packages should come with everything you need.  Not sure though anyone makes a reliable package for a 323ci.  I think they make them for the 330ci.  

Do a search for VF Engineering and Atlantic Downing for BMW Superchargers.

You will need to upgrade your brakes and suspension with the added power to completely be safe and benefit from the new supercharger.

Check bimmerforums.com in the forced induction section for an e46 BMW.

Answer 2

not much

if you want proper advice ring up a garage =D
