I want to build my Mercedes 2005 c230

So there is VERY little information regarding building a semi modern day Mercedes into a race car, especially on the forums.

So here it is, I want to build a track day, maybe hill climb beast.

I want to swap the motor, to possibly a turbo setup, bring in a manual transmission, race diff, light weight, electrical work, That's the hard stuff. I have some talented mechanics in my corner plus a shop. But I want to turn to you. (I can do a lot of the work myself)
