2-Rotor Services

We offer services for the 2-Rotor motors: 12A and 13B that improve its performance without compromising reliability. Several of our services will deliver high performance and yet still maintain driveability.

This page shows the services available for the 2 rotor 13B. If you are looking for a complete engine rebuild - go to our Engines category for 2 | 3 | 4 rotor engines.We offer a conversion kit for your RX7 that allows you to install a 3 rotor engine without chassis modifications.

Street-port Intake Service Service

Street Port Intake Service
Street Port Service smooths the ports on your rotary and improves air/fuel velocity entry into the chamber. We have three port types, Velocity, Qualifier, and Circuit. Circuit port is our largest, and most ideal for top end. Velocity was developed for factory turbocharger engines needing fastest spool and highest boost. Qualifier is ideal for any engine, providing best midrange with better top end over stock.

BridgePort Intake Service Service

BridgePort Intake Service
Bridgeporting adds a eyebrow to a exisiting sideport. This allows for very early port timing and will idle very aggressive. Just like a very large camshaft in a piston engine, this will provide the most power but with reduced driveability.
