Fuel delivery is taken care of by some VERY tiny Nippon Denso 145cc "green top" Injectors which are top feed and low impedance 2.4 ohm. It is also worth noting that at stock fuel rail pressure and 80% duty cycle the standard 145cc 4K-E injectors would only support 92.8 horsepower at the flywheel. After that you should either try to raise fuel rail pressure or upgrade to a similar top-feed low impedance injector to suit your desired power level.
