Re: help me keep my jeep
Although not a TOUGH swap (by swap standards) the 4.0 does require a bit of technical/electrical knowledge or at least some help, time, and a place to work on it for a while. You would be best off going this route, getting a running 4.0 from a later model YJ , the underhood wiring harness, the computer and computer wiring harness, and all related peripherals bolted to the motor. You will need a wiring schematic for both YOUR YJ and the Wrangler that the engine came out of so you can match up wiring...I don't think it is "Plug and Play". You will be much happier with the fuel injection and the 4.0 is a screamer of a motor.
The rebuilt 4.2 would be the easiest swap but probably a wash, money wise compared to the 4.0 (if you are using a used 4.0 and equiptment).
Trading the Jeep in is only an option if you are worried about dumping too much into a new motor or a swap, but keep in mind. The dealers that run push-pull-drag sales, usually have their vehicles marked up a couple grand above what they are really worth, so you really save nothing by doing this. You have just given your Jeep away to someone who won't appreciate it.
I say go for the 4.0 swap. You WILL have fun (keep telling yourself that during the proscess [img]images/graemlins/crazy.gif[/img]), you WILL learn alot about your Jeep, and you WILL come away with a better understanding of how things work.
