Turbo options for e46 m3?

Hello everyone! I recently bought my new baby a 2003 E46 (My first one), so I decided to join a forum. Any way. I was looking into Turbo kits to put on an e46 down the road and I could only find insanely expensive kits from HPF. I don't really want to drop 15k into a turbo when I only paid 17k for the car. I was looking on other aftermarket turbo sites and found one for only 1700. Is there something wrong with the kit since its only 1700? Are there any alternatives? Thanks

The Cliff Notes version:

"Normal" (non-M) BMWs have very high static compression ratios, M-cars, even more so. What this means in practical terms is that you`re limited to a relatively small amount of boost (unless you want to turn that beautiful engine into a very expensive grenade) Supercharging is considerably less expensive than going the turbo route, but you should *still* plan on a budget of $7500 to $10,000 to be sure all bases are covered.

Hotrodders have an old saying, to wit:
"Horsepower costs money....how fast do you want to go ?"

In your case, I would sign up for an HPDE class or two, and learn how to *really* drive that car before even thinking about adding more power.

Agreed. You can go a long way with knowing the full potential of your vehicle vs someone who doesn't. Plus class's aren't to expensive either.
