I have a 84 cj with a carbed 4.2. Someone told me about a kit that converts it to a MBI using a 4.0 head. Has anyone ever used one of these kits and does anyone know where I can get one? Thanks.:confused:

Not exactly sure what MBI is but your probably talking about MPI. Here are some articles I wrote a while back when I was running that motor. The 4.0L head and MPI made a big difference.

You can also put a MPI setup together yourself with a few trips to a junkyard.

Ment to be MPI, one of my fingers does what it wants to some times, thanks for the info.
