When it comes to rebuilding Renesis rotary engines, it's similar to an RX7 though still unique nuances that must be addressed. We carefully inspect and measure many parts, some can be cleaned and reused while others need to be replaced because they're too worn out.

While it might seem cheaper to use lots of used parts, it doesn't guarantee great results. An engine's performance depends on the quality of its parts. That's why we focus on using new parts to ensure longer-lasting and more efficient engines.

At Known Motors, we build engines that are meant to last for years with proper maintenance. That's why we replace essential components like apex seals, corner seals, side seals, and more. We use only new seals, gaskets, and other parts to ensure top performance and durability
