4-Rotor Services

We offer services for the custom almighty 26B 4-Rotor motor.

This page shows the performance upgrades available for a Turbocharged 4-rotor setup - or non turbo 4 rotor engine. See our Turbo Services page for services on Turbo's!

Street-port Intake Service

N/A Street Port 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.
