Greddy RZ. Not real common, similar to the Type S, sounds slightly different.

If i must be honest, i preferred the RZ to the S. (I've had both.) It's a little less ricey.

This was used on MY turbo MX6 for about 10k miles. In great shape, perfect working order.

$100 shipped CONUS.






Greddy Profec B and Turbo timer - $250 shipped CONUS

Complete, pulled from a car in working condition. Turbo timer does NOT have the Miata vehicle-specific PNP harness, but the main harness is there so you can wire it in yourself.

 

BOV sold.
