CBM MOTORSPORTS™ LS1 TO LS2 FUEL RAIL KIT Product Description:
This kit will fit all LS1 and LS6 injectors being run on a LS2 intake manifold with LS2 fuel injector rail. The factory LS1 injectors are approximately 1/4" taller then factory LS2 injectors. They also have smaller bottom o-rings then a LS2 style injector. Unfortunately if one tries to use a LS2 bottom o-ring on a LS1 injector it will still leak because the ID (inner diameter) is a different size. Because of this, a custom o-ring must be used. Our custom o-ring is significantly larger then the stock one is. Only the bottom o-ring must be changed as the top injector pocket on both fuel rails are the same size. We have also included a set of 4 CNC machined spacers and new bolts to accommodate the taller LS1/LS6 injectors.
Electrical: Positive M6 / Negative M5
