We offer services for the 20B 3-Rotor motor that improve its performance without compromising reliability. Several of our services will deliver high performance and yet still maintain driveability.
This page shows the performance upgrades available for the normally aspirated (NA) - or Turbo 3 rotor engine.
If you are looking for a complete engine rebuild - go to our Engines category for 2 | 3 | 4 rotor engines.
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.
Exhaust Port Service smooths the ports on your rotary and improves exhaust velocity from the chamber. We have both turbo and N/A ports available.
Wanting serious power? Look no further than Semi P-ports. Used on top rotary drag racers to develop over 1000 rear wheel horsepower, these are a great choice for many setups. We have sucessfully made 428 rear wheel horsepower with our naturally aspirated non-turbo 20b using semi P-ports.
Rotor Scalloping opens the port earlier delivering more torque, especially at low to mid RPM and lowers weight of the rotor.
Dynamic balancing achieves optimum performance for your rotary assembly allowing for maximum RPM with confidence. A must-have for engines going over 8,000 rpm.
