RX-8 Staged Fuel Upgrades

Fuel is the secret to generating good power reliably. An insufficient fuel system will cause even the best built car to experience engine failure. Below find what Esmeril Racing has to offer to take care of this most important feature.

Gas:

Stage 0 (360 flywheel HP, Gas):

This is a simple upgrade for users that just want help the stock fuel system out, whether it be because they have a turbo, many N/A upgrades or track the car regularly and want the added assurance. This is a drop in kit and requires no fuel management because it keeps the stock injectors. It includes the following:

  1. 1 X 255lph In tank Fuel Pump with harness.

Stage 1 (480 flywheel HP, Gas):

This is the same fuel upgrade that comes in our turbo kit. It flows enough fuel to support hp leves of 400whp and under. This will require a fuel management system since injectors are being changed. It is a drop in affair and includes the following:

  1. 1 X 255lph In tank Fuel Pump with harness.
  2. 2 X 1000cc Secondary Injectors.
  3. Swap your stock secondary injectors into the primary injector possition.

Stage 2 (600 flywheel HP, Gas):

This is for someone looking to push the Renesis to the limit on gas(We recommend using Race Gas for anything above 480 flywheel HP). This upgrade requires a fuel management system. This is a complete kit but requires a more complex install procedure where fuel lines are laid out, conversion to a return system, and brackets mounted for the external pump. It is by no means a hard project, specially if you were able to install a turbo kit on your car. It includes the following:

  1. 1 X 300lph+ External Fuel Pump.
  2. -AN Braided Hose.
  3. KG-Parts RX-8 Fuel Rails.
  4. 4 X 720cc Primary and P2 injectors and 2 X 1000cc Secondarry Injectors.
  5. Fuel Pressure Regulator.
  6. 1 X In-line Fuel Filter.
  7. All necessary fittings for installation.
  8. Uses Factory feed line as return line to tank.

E-85:

E-85 Stage 0 (N/A switch to E-85):

This kit allows users of N/A RX-8's to run the cars using E-85. E-85 not only costs less than gas but it has some properties like resistance to detonation and lower engine operating temperatures. Also, a noticealbe HP increase can be felt when makign the switch, even more notable when other upgrades such as intake or exhaust are present. The kit is designed to drop into place and allow the user to make the switch without having to use a fuel computer (some time will be needed for the ECU to adjust itself to run on E-85 after this conversion). It includes the following:

  1. 1 X 255lph In tank Fuel Pump with harness.
  2. 4 X 480cc Secondary and P2 injectors (use stock secondarries in primary location).

This requires a Fuel management system. It will yield the benefits of using E-85 to most costumers with Turbo RX-8's and inlcudes the following:
