Got an LS engine, but no computer or wiring harness? Not a tuning whiz? The EZ-EFI® LS Engine Transplant Kits allow anyone to easily run a LS Gen III/IV engine and transmission outside of the original vehicle and factory controller. The Engine Kit combines the revolutionary self tuning EZ-EFI® with the bolt-on XIM™ Coil-Per-Cylinder Ignition System to provide LS applications with the easiest, most advanced self-tuning electronic fuel injection system available. These FAST® kits are the perfect no-headache solution for transplanting late model engines into street rods, muscle cars or other projects.
