Too High PSI Port Injection Kit LT Engines
Most LT direct injection fuel systems will run out around 820-840WHP even with a larger fuel lobe on the camshaft and a proper low side fuel system. This is just the max capability of the components. Thankfully Too High PSI has a simple and cost effective way to add more fuel to our DI engines. This port injection kit is a bolt on solution to supply enough fuel for the 1200-1400hp range with 1000cc injectors.
TooHighPsi’s new “Patent Pending” KATANA Plates have been fully redesigned to be the thinnest port plates available for GM LT1/LT4 Gen V applications. They were engineered to minimize vertical height gain on the supercharger or intake manifold, making installation easier and providing more hood and cowl clearance for improved bolt access.
Included in this kit:
- THP Katana Port Plates
- THP Fuel Rails -6an
- Reflex Port Injection Controller
- Wiring Harness
- FIC 1000cc Fuel Injectors (8)
- Hardware
Fitment:
Valve Cover Requirements:
- KATANA Plates are designed to work with stock GM valve covers using coil pack relocation brackets.
- Direct fit for THP 2-pc LTx Billet Valve Covers, no relocation brackets required.
- Additional relocation brackets are not required if using Magnuson's coil relocation kit.
- If you have aftermarket valve covers, please call us to verify fitment.
Notes on Factory Variants:
- Direct fit for stock LT4 supercharger vehicle applications.
- Direct fit for LT4 CTSV and LT1 Camaro SS when using a Magnuson 2650.
- For C7 Z06 Corvette and ZL1 Camaro using a Magnuson 2650, our Billet 2650 supercharger lid is required to provide adequate hood clearance, otherwise the hood needs to be modified for fitment.
- Camaro/CTSV valve cover oil fill extension needs to be removed.
