I thought I would post up some pics of my 4.3 swap now that I have made some progress.
'98 4.3/700r4/Marine MPI intake/EDIS ignition/Megasquirt2 3.57 controller with relay box into my 85 4runner with 3" spring lift, 2" body lift......

Interesting.  I traded a late model OMC 4.3 setup to a local guy, not sure if it ever made it into his buggy, but I was curious how it would work out.

Interesting indeed.  I don't know much about MSII.  I'm using MSI-Extra in my DD MR2, running an EDIS coil pack also, but controlling it directly via the MS.  What prompted you to use the EDIS module?  Just trying to keep current out of the MS box?

All of the MS II material I found was based on using the entire EDIS system in concert with the MS, It's a simple installation
with the V3.57 ecm, prebuilt harness and relay box.

Those are AA headers, here is the link to the build thread. I still have to tune the VE and accelleration on the MSII but its already a huge improvement in power.
