Stanadyne BD LT1/LT4 Injectors and Pump 1200+ HP High Side package

1200+HP Direct Injection Fueling — No Port Injection Required

Take your Gen V GM LT direct-injection system to the next level with the Boost District Stanadyne + Goliath High-Performance Fueling Package.

This package combines a complete set of Stanadyne 7.5mm High-Flow Direct Injectors with the Goliath High-Pressure Fuel Pump, giving high-horsepower LT applications the additional fuel capacity needed for serious boosted combinations running gasoline or E85.

Most importantly, this is the same injector and high-pressure pump combination used on Boost District's record-setting C8 Corvette, making it a proven package for customers looking to push the limits of the factory-style direct-injection system.

Built for 1200+ HP Applications

Instead of piecing together a high-pressure fuel system, we've combined the pump and injectors we use in our own high-horsepower development into one complete package.

Whether you're running a supercharger or turbo system, the Stanadyne/Goliath combination dramatically increases the capability of the factory DI system and provides the fuel headroom required for serious power.

Package Includes:

• (8) Stanadyne 7.5mm High-Flow Direct Injectors
• (1) RGX Goliath High-Pressure Fuel Pump
• Compatible with Gasoline & E85
• Capable of supporting 1200+ HP combinations*
• Retains a true direct-injection fuel system
• Proven on Boost District's record-setting C8 Corvette
• Ideal for supercharged and turbocharged Gen V LT applications
• Professional calibration required

Proven by Boost District

We don't just sell this combination — we use it.

This injector and HPFP combination has been proven in Boost District's own high-horsepower C8 Corvette development, including our fastest C8 application.

For customers pushing beyond the capabilities of the factory DI system, this package offers a proven path to significantly more fuel capacity without immediately moving to a completely different fueling strategy.

Applications

Designed for 7.5mm injector-bore Gen V GM LT applications, including compatible:

LT1 • LT2 • LT4 • L83 • L86 and other Gen V LT-based combinations

IMPORTANT: Verify injector stem/bore size before ordering. Some later GM applications use 6mm injectors rather than the 7.5mm configuration included with this package. Your existing 6mm listing similarly advises customers to verify cylinder-head injector size before ordering. BoostDistrict

Tuning Required

Installation of high-flow direct injectors and an upgraded high-pressure fuel pump requires proper ECU calibration. Injector characterization, commanded fuel pressure and other calibration parameters must be configured appropriately for the vehicle and fuel being used.

Boost District tuning services are available for supported applications.

Horsepower Disclaimer

*1200+ HP capability is configuration dependent and should not be interpreted as a guaranteed horsepower rating. Actual fueling capacity will vary based on fuel type, commanded fuel pressure, injector window, engine combination, boost level, low-side fuel supply, calibration and other supporting modifications.

For extreme applications, contact Boost District so we can help determine the appropriate fuel-system configuration for your build.
