Direct fit Fuel injectors kits for GM and Holden VX- VY 5.7 LS1.
Options up to 1300hp and E85 compatible injectors.


Direct fit fuel injector sets for VX-VY LS1 5.7. All of these kits utilize full length, unmodified injectors that use the same Bosch Minitimer (square) electrical connector so there is no need for an adapter loom.

Depending on your Engines fueling requirements choose the recommended injector from the chart below.  All calculations are based on 3 BAR of fuel pressure, and this only what horsepower the fuel Injectors can flow. All horsepower ratings are flywheel.
