I was involved in a project that entailed a BoxsterS with a 997S 3.8L engine. The main problem on the market today is figuring out how to control the VarioCam PLUS which came on the 3.8S. After long hours, I was able to tune the car and control the VarioCam..
A Boxster with a 3.8L is awesome.. I'm a 911 guy, however after driving the 3.8, I'm looking for a Boxster to convert myself.
The conversion itself is VERY simple, you will be surprised! The electronics, well they are simple now
