KATANA Port Injection Plates - GM LTX / L8X Engines

TooHighPsi KATANA port-injection plates are a low-profile secondary-injector solution for GM Gen V LT and L8X engines. The 13.5 mm billet plates raise the intake manifold or supercharger approximately 15.8 mm while providing improved port transitions and multiple -8 ORB fuel-rail connection points.

Compatible engine families: LT1, LT4, L83, L84, L86, L87 and L8X.

Valve-cover requirements: Stock GM valve covers require the KATANA coil-relocation brackets. THP two-piece LTX billet valve covers fit without additional relocation brackets. Magnuson coil-relocation hardware can also provide the required clearance.

Application notes: Direct fit for factory LT4 supercharger applications and for LT4 CTS-V or LT1 Camaro SS applications using a Magnuson 2650. C7 Z06 and Camaro ZL1 applications using a Magnuson 2650 require the THP billet 2650 lid or equivalent hood-clearance modification. These plates do not fit the Magnuson L8T supercharger.

Injector fitment: Direct fit for 60 mm LS1-style long injectors. Short 34 mm LS3-style injectors require KATANA injector extensions.

Package includes: two KATANA plates, two-port and three-port fuel rails, four fuel fittings, four rail brackets and application-specific mounting hardware.

For ground-vehicle use in a controlled environment.
