OK - I called Brandon at Kleemann. They have done a couple Crossfires. He says it's a SLK Conversion, fits very neatly under the hood, real sleeper. Turns the sluggish old Crossfire into about 340 hp vicious little monster when done. He has experience in conversions already. They don't ship the kit however, they only do conversions at thier shop. Drive your car out there, stay in a real nice B&B in the Springs, two days later you have a new car! For information: KLEEMANN USA Inc.
