Motor sports sells a rotory AC compressor replacement kit. Has anyone installed one and is it worth changing over to the rotory compressor? Thinking of doing this upgrade. Please let me know your thoughts. Thanks

If I reacall correctly, that compressor is a Sanden SD508. It's a great compressor and the basis of many custom systems in hotrods, muscle cars, etc. It's what Vintage Air uses in most of their systems (again IIRC). I also had that same compressor in my 78 280Z which had an aftermarket (sometimes called "dealer installed") AC system. In the 12 years I had the car, I had no complaints. That system is, however, different from yours in that it had a center mounted evaporator which would always be more efficient than the systems that were used in the 240Zs that had the evaorator mounted in the passenger footwell. I guess the short answer woud be yes, the rotary compressor is worth chaning over to. It will cool better than the upright York compressor.
