Boost Dependent Fuel Pressure Regulator with Stock Injectors

Components Required


  • Stock Injectors
  • Boost Dependent Fuel Pressure Regulator (FMU)
  • Check Valves
With this option the stock Honda injectors, which are 245cc, are used with a boost dependent fuel pressure regulator. A boost dependent fuel pressure regulator increases the fuel pressure a set amount for every PSI of increased boost pressure. Most boost dependent fuel pressure regulators are modeled on Vortech's Fuel Management Unit (FMU) and look like the below picture. In most applications a 12:1 ratio FMU will suffice. This means that at any given boost PSI the fuel pressure will be 12 times that amount plus the stock fuel pressure which is about 40 PSI. For example, at 6 PSI the fuel pressure added by the FMU will be 72 PSI, added to the stock 40 PSI, will be 112 PSI of total fuel pressure. As you can see this is a lot of fuel pressure for the stock fuel system to take. Because the system is stressed so much more than it was designed for it is more likely that there will be a failure, especially an injector failure. If an injector failure occurs, sever engine failure will occur. Check valves will be required to keep the MAP sensor for sensing boost, a Missing Link check valve is recommended but plastic aquarium check valves could be used. The maximum safe limit for this setup is 6 PSI, going over this amount of boost will increase the chances of an injector failure.


Boost Dependent Fuel Pressure Regulator with Larger Injectors

Components Required


  • Larger Injectors
  • Boost Dependent Fuel Pressure Regulator
  • High Pressure Fuel Pump
  • Apex-I SAFC or VAFC
  • Check Valves
This is similar to the above option but instead it uses larger injectors and an Apex-I AFC to control them. With this option you can use a 12:1 or 10:1 ratio on the Vortech FMU depending on injector size. When replacing injectors it is important to match the correct type of injector with the correct OBD version of ECU. If you have a 90-91 Integra you have an OBD0 PR4 computer that uses peak and hold, low resistance, injectors. If you have a 92-93 Integra, or any VTEC engine, you have an OBD 1 PR4 computer that uses saturated, high resistance, injectors. When buying new injectors (available from RC Engineering) get the correct type for your application. If you must use peak and hold injectors on a OBD1 or later car, then follow the directions in the next section for adding resistors to the wiring harness. A high pressure fuel pump such as the Walbro 255lph pump or MSD High Pressure Fuel Pump PN 2225 is necessary to provide fuel at the high pressure that will be required. The Walbro pump can be installed in-tank or inline while the MSD pump can only be installed inline. If running the pump inline, disable the stock fuel pump. Although it is not necessary to remove the stock fuel pump, know that pumping fuel through the disabled stock fuel pump will slightly limit flow rates, but not pressure. Steel braided lines are a good idea given the amount of fuel pressure that will be required. The stock hard fuel lines and the stock fuel rail are good to over 400 horsepower, they do not need to be replaced. The Apex-I AFC (shown below) is used to de-tune the injectors so they will allow the car to run normally at idle and at low, partial throttle RPM. Check valves will be required to keep the MAP sensor for sensing boost, a Missing Link check valve is recommended but plastic aquarium check valves could be used. A common setup with this option is to use 320cc injectors which is good to about 12 PSI. Going much higher is very risky with an FMU setup.
