Product Details
Features
- Configured for GM LS3/L92 rectangular-port applications
- 100 lbs./hr. flow rate for high-demand fuel delivery
- USCAR plug style with included O-rings for a proper seal
- Set of 8 injectors, precision-matched for even cylinder delivery
Description
Configured for GM LS3/L92 rectangular-port applications, this fuel injector set supports precise fuel metering, consistent cylinder-to-cylinder delivery, and EFI calibration flexibility. Flow rate is 100 lbs./hr., with a high-impedance, 12V saturated circuit driver — match these specs to your ECU, fuel pressure, and engine fuel demand.
This set uses a USCAR plug style with male blade terminals (2 per connector). Seat-to-seat height is 1.480", with a maximum outside diameter of 0.580". O-rings are included: 0.580" manifold O-ring and 0.551" rail O-ring. Confirm fuel rail fit, intake fit, and injector depth before installation.
These injectors are designed for TSP Velocity intake/fuel rail combinations only and will not work with stock applications — flow rate, plug style, impedance, and calibration must be matched to your EFI system before startup.
Applications
Fits the following TSP Velocity combinations: 81003 LS3 Intake Manifold with 81009 Fuel Rails, or 81007 LS7 Intake Manifold with 81011 Fuel Rails. Not compatible with stock intake/fuel rail setups.
Specifications
100 lbs./hr. flow rate, high impedance, 12V saturated circuit driver, USCAR plug style, male blade terminals (2), 1.480" seat-to-seat height, 0.580" max outside diameter.
