WEAPON-X SPI Kit: Secondary Port Injection [Camaro, Corvette, CTS V, LT1 LT4]

The solution for big power needs is our secondary port injection and this is the same type of kit that GM opted to go with on the 2019 C7 ZR1 as well as many other high performance DI cars. We have come up with the complete solution for your high powered LT car. Our secondary port injection kit has it's own low side solution with a large pump to get fuel from the tank to the engine. This pump ties into the OEM fuel line as well as running up to supply it's own system. It is fully regulated and has a return, essentially transforming your stock fuel system into a high power capable system. Once the fuel reaches the engine, it ties into our custom billet fuel rails that tuck nicely against the supercharger/manifold, and what is needed fires through the 1000cc injectors and then the fuel returns back to the tank. The system is easily controlled with a proprietary piggy back controller with it's own software and we offer a base tune file and full support. Installation is made easy with our complete plug and play wiring harness!
