About the Chevy Crossfire Injection

by Andy Joseph

General Motors (GM) used the Chevrolet Crossfire fuel injection system in the Corvette from 1983 to 1985. The system increased the car's performance while also cutting down on its emissions.

GM engineers had emissions worries in regards to the Corvette. At the same time, they did not want to lose performance as a consequence. Fuel injection was the best system they could come up with at the time.


The Chevy Crossfire injection (RPO L83) made its debut in 1983. It used two throttle bodies on top of the intake manifold, and used a computer based on a Cadillac Digital Fuel Injection (DFI) unit to drive the system.


By 1984, Crossfire injection topped the Corvette's engine horsepower at 205, a 10-hp increase. Also, the fuel injection was able to reduce the car's emissions.


Despite the Crossfire injection's results, GM always felt it was capable of more than that. It might have served merely as an interim method of fuel delivery before the debut of Tuned Port Injection (TPI).


In 1985, the TPI replaced the Crossfire. It increased the Corvette's horsepower to 230, besting its predecessor's increase rate by 15 hp.
