My brother has a 2000 325i and wants to add a supercharger to it.

I drive a Z myself so I don't really know any mods for BMWs and such.

If any of you know any info, or know links to sites that have BMW modifications I would greatly appreciate it.

Thank you.

 

I dunno if they have any supercharger info for E46's... but here are some links.

Your bro could probably go to the discussion forums and ask the members there.

Hope this helps.
