What's included
Not included: transmission. It appears in some photos but is not part of this listing. Anything else visible in the photos is included unless noted.
Fitment
Interchanges with RX-8 applications; confirm fitment with your mechanic before ordering. Our team is glad to help you check compatibility.
Warranty
This rotary engine is sold as-is with no warranty. We strongly recommend replacing the apex seals before installation — rotary apex seals dry out and harden over time, which leads to weak compression. Every rotary we sell is verified to be free of seizing before it ships.
