How To Install and Modify GM Tuned Port Injection Systems. From the earliest small-block Chevrolet engine produced in 1955 to the brand new modern small block, all are candidates for the latest high-tech TPI fuel injection systems. Street enthusiasts, hot rodders, show car builders, and performance seekers are turning to the TPI system. Salvage yards, aftermarket dealers, and factory parts counters are the sources for these systems. Retrofitting a TPI system to an older engine isn't exactly rocket science, but is does require a good deal of knowledge, not only of basic induction systems, but also computerized controls and circuitry. This manual takes the reader step-by-step through the fuel injection system and the retrofitting of a TPI system to a typical Chevy small-block motor.
