Thanks for considering Rotary Resurrection for service for your RX-8. At this time I offer no new or used parts for the 8. I can offer rebuilds for the Renesis powerplant should the need arise, however I have no cores or core stock on the shelf for the relatively new engine due to the prohibitive cost and very low demand.
Most all of these vehicles will be under dealer warranty for some time to come, so for the most I have not yet moved into repairing RX-8's yet. However, I am now an rx-8 owner myself and am constantly working on my own car and researching the platform in preparation for doing customer jobs.
Should the need arise to seek a replacement engine somewhere other than mazda, please contact me directly with your unique situation so that I can evaluate your needs and possibly obtain price quotes for whatever replacement parts you may require. I do not yet have a pricing scale set up for Renesis engine repair, rebuild or installation at this time, and this will be decided on an individual basis. I can almost guarantee that my rates would be far less than that of mazda or any other high end rotary shop, however.
Nevertheless, expect the cost to rebuild your blown renesis to be significantly higher than that of the older rotaries. In those older engines, apex seal breakage usually meant that you needed a replacement used rotor and rotor housing to make the engine whole again. Due to the new design, when a renesis actually breaks apex seals, not only does it still destroy the rotor and rotor housing, but since there is no peripheral exhaust port for the seal fragments to exit, they get thrown around inside until they find their way into an intake or exhaust side port. In the process, they wedge between the rotor and port closing edge, damaging the adjacent iron housings as well. This extra damage (4 of the 8 major parts in the engine) coupled with the fact that renesis cores are hard to come by and new parts are expensive, will make the rebuild costs considerably higher than what we are accustomed to.
