When doing any boost install to the Lexus IS300 one must take absolute consideration of the limits of the engine, fuel system, engine management and operating environment before you find yourself with a blown motor.

There is much discussion on how much power the stock fuel system, engine management system, etc., the motor can handle. It is our "base" experience that on the factory small fuel injectors you can run about 285rwhp safely. Safely would be defined as injector duty cycle limit not exceeding 85% with an air fuel ratio under boost of 11.5 to 12.0 to 1 on good quality premium unleaded fuel. I know people have made 375rwhp on factory injectors, but this is our opinion of safe, not everyones.

Because we sell quite a few budget turbo kits to the 2JZGE IS300 customer, we wanted to put together what we refer to as our Stage 1.5 IS300 Accessory Kit. This kit contains our SupraStore.com return fuel system set-up package (details below), AEM UEGO Wideband and AEM FI/C for help in fine tuning those with entry level boost kits.

Not every customer requires the complete Stage 1.5 Accessory Kit and frankly, some just want to swap their IS300 from the non-return line factory style fuel system to the "required" Return Fuel System, which is a must for any boosted application in the IS300. Without this, you cannot successfully install a fuel pressure regulator.

I said all that, to say this. We have this Fuel System Set-up Package which converts your factory fuel system to a return style fuel system. All parts are in this kit. Figure an afternoon to do the install for an experienced mechanic.

This kit contains the following:

Return Fuel Line Package

FueLab or Aeromotive 1:1 Rising Rate Fuel Pressure Regulator -6

Nylon braided 1000psi rated fuel line kit

All AN-style fittings

Fuel pressure gauge (mounts to FPR)
