I recently ordered you book Jeep cj rebuilder's manual. It is due to arrive June 21. I am putting a 1994 yj 4.0 engine into my 1982 cj8. I did this about 20 yrs ago and used hesco harness. They don’t offer this any more but it looks like I can order one from mopar performance with the same part number p5007148 as the old hesco number. Would you have any idea if they are the same. Any help would be appreciated. Thanks, Bill Himelright
So I picked up a 2004 XJ 4.0 engine and didn't realize the many differences in the block casting from the older 4.0. It wasn't until I started doing more research on the engine that I realized this, but I did get the engine for a really good price that was too good to pass up. Being that I've already put in some time into this engine, I HAVE to make it work. The first issue that I ran into was with the driver's side motor mount pads on the block. on the older 4.2 and 4.0 engine, the top bolt pad is pushed back about half an inch, and on the XJ 4.0 they are flush with each other. So, I went ahead and cut the top one off about 1/2" and that left enough thread for the bolt. There is some space between the mounting plate and the block, but not much, that I am going to use washers. I'm hoping that will work. For the passenger side, I had to do some cutting on the CJ7 motor mount brackets and a bit on the block due to block webbing interference. Now, the next issue that I am facing is with serpentine accessory drive. I wish that I could just use the 4.0 accessories, but being that I did not get the harness and computer with the replacement 4.0, I am going with the carb setup. So I will be using the 4.2 intake. Unfortunately, the water pumps are different. The older 4.0 engines have the built-in power steering bracket on the pump, so it's not like I could go this route to solve my power steering issues. This is starting to be somewhat of a headache because it is turning out to be a much more involved swap than I thought. I wish that I could just go the fuel injection route and be done with these issues. This would allow me to use all 4.0 accessories without an issue.
I stumbled onto this forum while researching my 68 Jeepster Commando rebuild. What a great bunch of folks, thanks! I currently have a 225 v6, running good, but stock. I've built and added bumpers, winch, rock sliders etc. so with all that and tools its gained a bit. Also running 33" tires, 4:56 gears with a SM 465 and Dana 20. My dilemma is should I rebuild the 225 (which is my first inclination) or try to find an EF 231? So far my plans for either one would be a stock rebuild but with Comp 252H cam, Offy dual plane intake with EFI and dual exhaust. I want to stick with either the 225 or 231 because I want to just drop one in, and I've been working on this for long enough. I would like more low and mid range power. Any thoughts would be appreciated. Scott
So the engine in my 1990 wrangler has gone over hill. The cylinders are scored and they are already bored .060 over. A good friend of mine has found a 1998 engine still assembled (it was removed because the owner put a bigger engine in). It also has the 5 speed transmission if I'm not mistaken the ax5 and transfer case with it. its quite a deal, but my question is would the block be able to fit in the 1990 wrangler? If I get parts for it would I need 1998?
