Power 5,

Thanks for the tips. The Merdedes SLK market never got to have a very big performance aftermarket for it. Yes there are nice performance upgrades for our cars right now but they are terribly expensive. A 330hp upgrade will cost about 11k and a 407hp upgrade will cost about 20k. The market seems to be targeted to those with more play money than I have. Somthing to boost 50 HP while maintaing a good torque curve in this car would make most people happy.

I think most of us are looking for a lower cost alternative like a Turbo setup or a low boost SC (the current one requires new pistions and crank) rather than buying the fugly SRT-6 version of our cars (the wale fin that I am sure is laughed at in all forums). The compression ratio on our car is currently 10.0:1 and I am not sure how much more the setup can take while being reliable. I am surround with people at work that can modify a ford, chevy or mopar engine with their eyes closed but they all find out that my car has a MB engine and run away.

Right now the cheapest alternative seems to be to pull your own engine and have it bored out to a 3.8 liter setup. You would still have to tow it out of town to have the fuel mappings fixed, but that is another story.

Here is hoping for more upgrades for both our cars.
