EFI 3x™ 4.3L V6
Whether you are updating your early 4.3L V6 electronic fuel injection system to use a newer ECU or adding electronic fuel injection to your 4.3L V6 engine for the first time, an EFI 3x 4.3L V6 conversion will equip your 4.3L V6 Chevy engine with the crank and cam signal components necessary to be controlled by 1996-newer GM ECUs.
EFI Connection's 3x 4.3L V6 systems are designed to output the 3x crank and 1x cam signal of a 1996-newer 4.3L Chevy Vortec V6 engine. This means that the popular GM# 12200411 PCM can be used with single coil and distributor ignition for 3x equipped 4.3L V6 Chevy engines!
The differences in the variety of available 4.3L V6 engines required us to design and manufacture many different 3x 4.3L V6 conversion kits. Get started by using the conversion matrix below to choose the appropriate 3x SBC conversion for your engine.
