EFI 24x™ LT1/LT4

Since 2008, our 24x LT1 conversions have been eliminating the optispark distributor and transforming LT1 engines.

EFI Connection's 24x LT1 systems are designed to output the 24x crank and 1x cam signal of a GM Gen III LS-Series engine. This means that LS1 compatible ECUs can now be used on 24x equipped LT1 engines!

The differences in the variety of available LT1 engines required us to design and manufacture many different 24x LT1 conversion kits. Get started by using the conversion matrix below to choose the appropriate 24x LT1 conversion for your engine.
