Rotary Engine Builds for power

For our climate, it is paramount that every engine build gets performance / reliability upgrades that match the application. Cooling is a big issue here in Colorado.

The 13B full race engine build

Our race motors get that extra bit of what is needed for high RPM pulls over and over again. Here we have a street port 13B coming together. 

  • Competition race rotor bearings
  • polished ported intake / exhaust from quality flow-bench data
  • Performance Ceramic Apex seals for lightweight, high heat resistance and keeping high pressures without tearing up rotor housings.
  • Rx8 E-shaft, completely balanced with oil flow upgrades
  • Rx8 Rotors, machined for Rx7 style apex seals, scalloped / balanced within a gram of each other.
  • 5.5 inch racing dual clutch discs / lightweight flywheel
  • Increased end play for high RPM / heat expansion
  • Oil galley upgrades, dedicated front / rear bearing oiling
  • Dry Sump, no oil pan for lower center of gravity
  • Large oil coolers 15" x 11" (2) with minimal pressure drop

Details matter. This motor will get a IDA intake with 4 1000cc injectors along with dyno tuning for maximum power.

Before you get into your rotary engine build / rebuild, know your expectations / budget. Solid builds come from realistic expectations and quality craftsmanship.
