Features:
IAG provides a simple fuel rail solution that lowers the conversion cost to top feed injectors on older Subaru STI's, Foresters XT's and Legacy GT's. The conversion kit allows you to keep your side feed TGV's in place, simply swap in our injector conversion bosses, new conversion rails, hardware and your choice of top feed injectors.The IAG Performance Side Feed to Top Feed Fuel Rail Conversion Kit is designed to increase the power ceiling on your Subaru's fuel system. The factory fuel rails function in a series, which means that each cylinder's fuel is delivered after the other. As horsepower rises past the 350whp mark, the stock rail often does not have the capacity to deliver fuel to the last cylinder effectively. As a result, that last cylinder can run lean, which can result in catastrophic failure. These billet fuel rails will eliminate this problem.
First, IAG's fuel rails operate in parallel format, each cylinder bank receives equal fuel, matching the flow between the rails to ensure that each injector sees the same fuel pressure. Second, the bore of our rail is machined to 5/8" ID and is designed to accept -8 O-ring boss fittings. This configuration greatly increases the volume of the rail which means that more fuel is available at higher power levels. These fuel rails were real-world tested to 850hp.
