my car came with the original piston type compressor made by york i believe. it still works fine but i want to update the compressor to the new rotary type which is less taxing on the engine. i would appreciate suggestions/tips from members who have taken this route before. can anyone recommend a brand and model of compressor? thanks! :)

The Sanden 508 or 505 will work but will need an interface bracket if you use the original compressor bracket.

The Sanden 508 is available with the R-12 service port if you want to stay with original freon. If you are updating the compressor you may want to go to the more environmentally friendly and readily available, R-134. If you do, you may want to replace the condensor with a modern cross-flow condensor to make up for the lower efficiency of the gas. Either way you go, you should replace the dryer too.
For mounting to the existing bracket, the York to Sanden adapter is about $35.

most modern aircon compressors are rotary type(sanden, nippon denso, etc.) and are very easy on the engine when engaged. you cannot actually feel the compressor engaging when driving the car. the york compressors that came with the car are of the piston type(like a small engine) and can sap some power from the engine when engaged. i dont know about actual horsepower loss but it is discernible when driving the car. :)

Ray's right--if you go R-134A, chnage out the stock condensor for a more efficient parallel flow one available through a number of aftermarket A/C suppliers. You'll need to chnage out the hoses for the more modern barrier type with the o-ring type fittings. You'll need to have these made up custom for your application.

Hi george, thanks to you and ray i decided to take the R-134A route. my aircon supplier is preparing all the materials for the conversion and will schedule the work next week. thanks!
