I have seen the Startech, Kleeman and other crazy priced kits. It seems as though very few people who buy a Mercedes know how work on their own cars and are more than willing to pay astronomical prices to get the work done. There are many of us that have gained experience modding other cars and we are now starting to buy Crossfires. for example, I have built some kit cars / replicas (Cobra and GT40) from bare frames and had to come up with my own brakes. So when I bought a Mini and they guys couldn't afford the Brembo kit, I came up with my own kit and sold for less than half the cost of anything else on the market. When I got out of Mini's I sold the business to Detroit Tuned See Link:

Anyone want and big brake kit for the Crossfire?

Building kit cars also taught me that you can use just about any new engine in any project as long as you get the whole engine with all accessories, the engine wiring harness and the computer. Other than the cost for these parts the only other real expense is getting the exhaust hooked up. Putting a Mercedes V8 into a Crossfire looks like an easy natural swap (or at least easier than any other swap I have done).

I think it may be easier and cheaper to just add a supercharger or turbo. I am interested in learning more about this new compact supercharger: http://www.rotrex.com/
