WJ to XJ Engine Swap
 

As I mentioned earlier, Grace's WJ was involved in a rollover and it
looks like it's probably totalled... The engine was still running
after the rollover and my examination of the vehicle on Sunday made me
start to wonder if perhaps the engine could be salvaged... So, how
much trouble would it be to take the V8 engine from a 2001 WJ
(Limited) and put it in a 1995 XJ? Will it even physically fit?

As far as I know, the New Process transfer cases all have the same input
adapter bolt pattern. This means that you could probably bolt your WJ
transmission right up to the XJ transfer case. The transmission tail shaft
might not fit the TC input, but there should be a replacement TC input shaft
that works. If this is not the case (pun intended) then you could drop in
the engine to transfer case as a unit. Then you have engine mounts,
transmission and transfer case mounts, shorty headers (where do you get
those?), drive shafts and wiring to worry about, to mention a few of the
main obstacles that come to mind.

I am sure that it will fit, because after all people have put Chevy 350
engines in there, but I am equally sure that something will hit some part of
the XJ the first time you drop it in, no matter how careful your
measurements. Then, you may be faced with an "interesting engineering
challenge" or two.

Is this for novelty value, or do you think it will give the XJ something,
that it does not have now? My advice is to let the recyclers sell it to
someone who needs it.

Be careful that it wasn't running for long whilst upside down since
the oil pressure would have dropped. A friend replaced the body on a
car once after a roll over, only to have the engine seize a few
thousand miles later due to the previous unseen damage by oil starvation.

Well, the engine on my XJ has probably around 120K miles on it whereas
the engine on the WJ has less than half that... I did not change the
gear ratio when I put the larger tires on it and it is a bit anemic on
accelleration... The WJ had very good accelleration with the 235 hp
V8... I guess it's more of an issue of trying to not waste something
as long as it doesn't get too expensive in the process...
