Description
The FiTech Ultimate LS7 750HP Square Port with Transmission Control + Inline Fuel Pump Master Kit (Part No: 71018) is a high-output, self-tuning electronic fuel injection, intake manifold, and electronic transmission management package designed specifically for modified GM LS7 V8 engines with square (raised rectangular) intake ports. Combining high-capacity fuel injectors capable of supporting up to 750 horsepower with integrated control for electronic GM automatic transmissions, it offers a complete drivetrain induction and control solution in a single kit.
System Architecture & Performance Highlights
LS7-Specific Port Configuration: Engineeryed specifically to match GM LS7 square/raised-rectangular intake ports, ensuring correct runner alignment and leak-free port sealing.
Integrated Transmission Control: Features built-in electronic control for GM 4L60E, 4L65E, 4L70E, and 4L80E automatic transmissions, enabling custom tuning of shift points, shift firmness, and torque converter clutch (TCC) lockup via the handheld touchscreen.
750HP High-Flow Fuel Injector Package: Equipped with higher-capacity fuel injectors sized to support high-output, naturally aspirated, or modified LS7 engines generating up to 750 horsepower.
Complete Intake-to-Tank Master Package: Pairs a black anodized fabricated aluminum intake manifold, high-flow throttle body, billet fuel rails, injectors, and self-tuning ECU with a full external high-pressure fuel delivery setup.
Plug-and-Play Wiring & Control: Fully labeled automotive-grade wiring harnesses for both engine sensors and GM transmission solenoids eliminate harness cutting, splicing, or factory ECU re-flashing.
255 L/PH Inline Fuel Delivery: Includes an external 255 L/PH high-pressure inline fuel pump, dual billet filters (100-micron pre-filter and 30-micron post-filter), and 20 feet of high-pressure EFI fuel hose with push-lock fittings.
Color Touchscreen Handheld Controller (Engine & Transmission Parameters)
Installation & System Sizing Notes
Port Shape Verification: Confirm cylinder heads feature LS7-style square/raised-rectangular ports; this intake manifold will not seal on standard LS3/L92 rectangular ports or early cathedral-port heads.
Fuel Pump Capacity Threshold: While the intake manifold and injector package are calibrated to support up to 750 HP, the included 255 L/PH external inline fuel pump is rated for applications up to 600 HP. If your build produces over 600 HP, upgrade the fuel delivery system to a higher-volume unit (such as an in-tank 340 LPH or dual-pump setup).
Transmission Wiring & Setup: Connect the dedicated transmission harness directly to the main 13-pin connector on the 4L60E/4L80E transmission case and set tire height, axle gear ratio, and shift parameters using the handheld touchscreen.
Oxygen Sensor Placement: Weld the included wideband O2 sensor bung into the exhaust header or collector pipe at least 18 inches downstream of the exhaust ports and upstream of any catalytic converters.
