WRX STI Fuel Injector Guide
Choosing the correct injectors for your STI build is key to making reliable power with smooth better than OEM drive ability. Here at Brewed, we exclusively use injector dynamics injectors on all of our builds. over many years of testing injector dynamics have proven to be superior to any other injector on the market. of course injector dynamics offers a wide range of sizes perfect for any sti build on gasoline e85 flex fuel or even methanol.
Starting off with the ID 1050X these injectors are perfect for any stock turbo Sti with or without both on mods. The ID 1050x is also perfect for any stock turbo Sti, looking to run E85 or flex fuel. as you can guess based on the these injectors flow 1050 cc at the OEM 43 psi fuel pressure. The ID 1050 X injectors are a popular choice for all of our customers running stage, one to stage two mods, including an intake exhaust and boost control solenoid.
Those planning to upgrade their turbo to something larger than OEM should consider using the ID1300-xds injectors. The ID1300X is the ideal injector for any STI planning to make up to 650hp on gasoline or 550hp on e85. Flowing 1300cc at only 43psi and over 1600cc at 75psi the ID1300-xds is a truly versatile injector that will keep a stock engine idling smoother than the oem injectors.
ID1300X injectors are the most popular injector we sell for the Sti and WRX. These are the ideal injectors for some thing like a FP blue stock location turbo or ETS V band G30 turbo kit. At this power level the ID1300X are perfectly matched with the Hell Cat fuel pump listed below.
