RX-8 AC compressor 6 rib pulley modification

The RX-8 AC compressor has been common to use when converting to R-134a systems. The RX-8 compressor has a 4 rib pulley, and I wanted to use a 6 rib design like what was originally on the car. I did trial and error ordering a couple aftermarket ac clutch and pulley kits before finding one that works. Using only the pulley from this kit https://www.aliexpress.us/item/2251832722867570.html and the rest of the parts from the RX-8 compressor worked best. I've run this setup for 2 years without issue. The videos below show how to remove, install, and verify alignment. Another person can buy the SCSA06C compressor for the Corolla new and try that. For the rest of us who already purchased new RX-8 compressors, there is an option to modify it with the 6 rib pulley.




Removal

Installation

Alignment

Nice, thanks for sharing and do you have any other tips when doing a RX8 compressor conversion?

No specific tips that aren’t in other threads. The JP3 Motorsports conversion kit is great quality. I used a new Denso compressor.

I believe this is the clutch. I'm not 100% on this, as there is a small difference in the compressor number from the original link, but this is the clutch for the MR2 compressor, so hopefully this would work as well. It's definitely a bit more than the 40 some bucks from the other link, but this shows the part number for the clutch, so maybe it could be shopped around.

I reached out to the company that was listed in the OP’s link and they responded right away with pricing. They can sell just the clutch and pulley, it’s about $28. Shipping is about $43. I’m going to order the part, I will post the results here when I get it.
