I was wondering, I have a 90 Wrangler 4.2 ltr. Is it legal to swap a newer 4.0 FI motor in? I guess I'd have to yank out the computer etc.. Should I pull the Engine tranny and Transfer as a unit? I've never swapped in a computer controlled engine before.
Here in CA you can ONLY swap in a newer motor. so you should be fine. if your in CA, call Turbo City (i think they are in anaheim)they may offer a kit. if not call 4 Wheeler Supply in huntington beach (Gary puts those new 190 hp. mustang sixes in jeeps!)and they should be ably to tell you what you need to know.
