What's included
Anything else visible in the photos is included unless noted otherwise.
What you'll receive
We stock multiple examples of most engines, and the unit photographed is one of them. If this particular engine has sold we'll match you to another in the same condition and mileage range. Before anything ships we send you photographs and the serial number of the actual engine you're getting — you approve it first.
Before you install — apex seals
Rotary apex seals dry out and harden with age. Brittle seals crack, and that shows up as poor compression. We strongly recommend replacing the apex seals before installation. Every rotary we sell is verified free of seizing before it ships.
Fitment
This is the 6-port Renesis paired with the automatic transmission, and the ECU is included. Confirm which port configuration your car uses before ordering.
Warranty
The rotary engine is sold AS-IS with no warranty — final sale. The included transmission carries our 30-day transmission warranty. Full terms at jdm-online.com/pages/warranty.
