Description
Description
This package includes a set of 8 Gen II LT4 GDI +30% Injectors and 1 Lingenfelter Big Bore Direct Injection High Pressure Pump
Part Number: FICGDI-P
These are designed for the new GM LT series engines. With a 30% increase in flow over stock LT4 injectors, these supply the needed fuel flow for high horsepower applications without having to resort to auxiliary fuel systems. These injectors utilize the same nozzle that was designed by GM, which is the best design for these engines. All modifications are internal utilizing the same coil and original characteristics programmed in the ECU from GM.
Testing done by major companies such as Lingenfelter Engineering and Vengeance Racing have shown excellent results in tuning by just modifying the fuel tables and leaving the offsets alone. The injectors are E85 compatible allowing higher output engines to take advantage of the capability of E85 fuel.
Applications:
- High horsepower GM Gen V V8 and V6 direct injection engines including LT4, LT1, L86, L83 and LV3 E85 conversions of GM Gen V V8 and V6 engines
- 2014-2017 C7 Corvette LT1
- 2015-2017 C7 Z06 Corvette LT4
- 2016-2017 Camaro SS LT1
- 2016-2017 CTS-V LT4
- 2014-2017 Silverado and Sierra with 4.3L LV3, 5.3L L83 and 6.2L L86 engines
- 2015-2017 Suburban, Tahoe, Yukon and Escalade with 5.3L L83 and 6.2L L86 engines

Description:
Mechanical fuel pump flow has been one of the primary limiting factors for the aftermarket when trying to increase the power output of the GM direct injection V8 engines. The Lingenfelter Big Bore direct injection fuel pump for GM Gen V V8 applications provides an increase in fuel flow capacity over the stock LT1/L86 and LT4 fuel pumps, expanding the range of performance of these engines. At 12.0 mm in bore size, the Lingenfelter Big Bore pump flows over 30% more than the stock L86 & LT1 pump and nearly 10% more than the LT4 pump
Tested to provide over 1,100 horsepower of fuel flow for a turbocharged LT4 engine on gasoline and nearly 900 hp of fuel flow for the same engine on E85
Features:
-Precision machined and assembled fuel pump assembly using brand new production LT1 fuel pump cores
-12.0 mm diameter bore size
-DLC coated bore and piston
-Compatible with production LT1 and LT4 fuel pump lobes and with aftermarket higher lift fuel pump lobes
-100% hot tested pump assemblies to confirm performance and functionality
Benefits:
-Over 30% more fuel flow than the stock L86 and LT1 fuel pump
-Nearly 10% more fuel flow than the stock LT4 fuel pump
-Increased fuel flow allows higher power levels without having to resort to auxiliary fuel systems
-Direct fit replacement with no modifications required
-Stock OE look exterally
-E85 compatible
-Can be combined with higher lift fuel pump lobes for even great flow rate increases
Some aftermarket higher lift fuel pump camshaft lobe designs may require a lash cap to compensate for the smaller camshaft base circle
Some aftermarket higher lift fuel pump camshaft lobe designs may require a higher load spring on the pump to maintain fuel pump lifter control
Fuel pump lobe size 5.7 mm LT1, 5.99 mm LT4, 6.5 mm GT35
