FiTech Retro LS TBI 650 HP System Regulated In-Tank Pump Fuel Injection Master Kits
FiTech Retro LS TBI 650 hp system regulated in-tank fuel injection master kits deliver old school looks and modern EFI performance for your hot rod.
These kits feature a FiTech classic carburetor-gold throttle body with transmission control and a pre-terminated wiring harness with specific LS engine sensors, including the factory knock sensors to complement the built-in timing control. The remote ECU can control the transmission shift points and characteristics of the popular 4L60/65/80E transmissions. No laptop is required, and the system will work on 24x or 58x cam sensors. Also supplied with the Retro LS TBI is a handheld touch screen controller, cable and windshield mount, WBO2 sensor, bung kit, gaskets, mini USB cable, instructions, and warranty info.
For fuel delivery, FiTech Retro LS master kits pair the TBI with either a 255 or 340 lph Go Fuel in-tank regulated pump. Both offer a simplified single line system with a depth of 6 1/2 to 15 in., making them suitable for most EFI-ready tanks. They also feature a -6 AN pressure port and a 4 bar (58 psi) regulator. Choose the master kit with your preferred fuel delivery system.
