Any info you care to share or links on running the sohc on OBD1?
i have no links to share. my tuner got me in contact with a guy who did it. i will be making a DETAILED thead with lots of pictures and all info once its running.
But i did some eye balling and heres what ive gathered so far.
blocks are basically identical. motormount bolts are in the same spots.
factory mounts the oil pan will just barely hit the crossmember, but with auto fab mounts itll clear.
all the obd1 sensors from a 4.0ohv match mounting wise onto the sohc, theyre just in different spots
so IAC
crank sensor
coolant temp sensor
maf
those swap over from your ohv to sohc with wiring lengths changed.
cam position sensor will not swap over and im not sure how to wire one in because the two operate completely differently, this is no issue, can be ran without it and / or tuned out by a tuner so im not even worried about it.
if you run it without a cam position sensor, you will have a CEL.
the coils are exactly the same. doesnt matter which you use
injector wiring plugs TBD
alternator tbd
all egr and smog bs im not figuring out cuz im not running it
nor do i have ac so ill be no help there
custom power steering lines will have to be made.
bell housing bolt pattern is the same. so yes i will be keeping the c4
