LS1 Retro-LS 750-HP Port EFI System with Cast Intake by FiTech®

A cast-aluminum manifold, billet rails and transmission-control ECU combine a classic look with port EFI.

This FiTech® Retro-LS system uses a cast-aluminum intake with a 4150 flange for LS1 cathedral-port cylinder heads. Billet fuel rails supply 55-lb/hr injectors positioned at each intake port, providing port fuel delivery within a traditional four-barrel-style induction layout. The system is rated for up to 750 horsepower on gasoline and supports appropriately configured boost or nitrous combinations. The kit includes a Classic Series throttle body, injectors, rails, a fuel-pressure regulator, -6 AN and -8 AN fittings, dual oxygen sensors and an ECU with GM® 4L60/4L80 transmission-control capability. Matte-black and gold appearance options are offered.
