After many requests from Subaru owners, T1 Race Development came up with a solution for those stuck with a side feed injector and a severely lacking selection of fuel injectors. In the past, it was required to source the Tumble Generator Valves (TGV) from another Subaru application with top feed injectors and swap them and the fuel rails to convert to a top feed injector setup.

Not anymore. T1 has developed a new Injector and Rail Combo that will allow you to fit any of the Injector Dynamics lineup into your side feed TGV’s with ease.

The T1 rail conversion will cover it all from mild to wild with 725cc/min, 1000cc/min and 2200cc/min injector options (all injectors are high impedance, eliminating the need for injector resistors or peak and hold injector drivers).

The rail and mounting spacers are CNC’d aluminum and are black anodized. The kit also includes 8mm stainless steel mounting hardware as well. Inlet and outlet threads on the rail are -6 AN female and seal with an o-ring, leaving plenty of flexibility for plumbing options.

The rail kit is only sold with Injector Dynamics injectors. Each kit consists of 4 injectors, 4 injector connectors, 2 rails, 4 spacers and 4 SS allen head mounting bolts.
