FAST's Transplant Kits have taken all the guess work out of fitting a crate or junkyard engine into your project. Our kits contain everything you need to transplant your LS1 or LS6 design engine without needing to modify a factory harness or tune a factory ECU for your custom application. Your project deserves a kit that was crafted by fellow gearheads who know what it takes to swap an engine. This LS1/LS6 kit contains our XFI 2.0 ECU, XIM ignition controller, along with Main, Injector and Ignition Harnesses to power your project. This kit connects directly to your factory ignition coils and throttle body for a plug and play experience.This Part Fits: Year Make Model Submodel 2004-2005 Cadillac CTS Base 2004-2005 Cadillac CTS V 1998-2002 Chevrolet Camaro Base 1998-2002 Chevrolet Camaro Z28 1998-2002 Chevrolet Camaro Z28 SS 2003 Chevrolet Corvette 50th Anniversary Edition 2003 Chevrolet Corvette 50th Anniversary Edition Pace Car 1997-2004 Chevrolet Corvette Base 1998 Chevrolet Corvette Indianapolis 500 Pace Car 2001-2004 Chevrolet Corvette Z06 2004 Pontiac GTO Base
