Turbo kits

There is a rumor going amongst 03 M3 owners that the new turbos can not wirk with the car itself. Is this true

What do you mean by that? If your saying that you need a new chip to work a turbo on a BMW then yea, thats true with many cars.

BTW. I havn't even found a turbo kit for the E46. I would love it if you could provide a link.

iam not sure they even make a turbo for the E 46 but they make a supercharger right?

Yup, I've read articles on an Active Autowerk supercharger.

they make a supercharger for 330CI i think you would be better off going with that because it cost less than M3 and the insurance is less. I wondering this because my sister wants an M3 and i have and my parents dont wont to buy her an M3 but she likes fast cars. Have any suggestions

Get her a nice 1999 325is...if you put a super charger in that baby it flies, and you can make it all "m3" for a very cheap price, and you can find those for cheap....But if u must go with the e46....ne of them r fast...lol r'nt they?
