So obviously, one of the ways is a turbocharger. I believe (not sure) that the engine is a B230F, although I could be wrong. I'll check tomorrow morning to be sure. How difficult would it be to turbocharge this thing, and what kind of gains could I expect to see? What kind of pre-turbocharging things should I check before doing anything at all?

There don't appear to be any oil leaks, so at least that's good to go.

BTW, the car has about 133K miles on it.

*edit* Yep, just took a look. It's a B230F.

There's no aftermarket thing that's doable? Or it just needs heavy modification to work on the B230F? Also, how about an engine rebuild? Does doing one of those usually bring back a lot of the life of the car? I guess I'm just trying to decide on something "fun" to do on the car that'll give it some more kick. ;-)

Thanks for all the info again.

Very expensive and difficult to turbocharge (requires new engine and exhaust). Instead, sell the car and buy a turbo or a B234 GLE.

assuming you new to performance mods... one of the easiet things you can do is a cone filter. mount it righ on your amm. second would be a big exhaust. to turbocharge the engine... guess what. Your going to need a COMPLETE turbo engine from a wrecked car. Your mechanic could do this for you but it would cost a bundle.
