Xj engine swap,, 94 longblock into 91 xj
HI Forum members
First post here,, need some technical advice,,
I need to know if the 94 to a 91 xj swap is going to be a nightmare
or reasonably no big deal,
Engine management system and electrical connections being the
major hurdle. reviewing the schematics and sensor configuration
it is basically a downgrade from the 94,
some of the pigtails to the sensors will have to be sorted out,
but that is not a deal breaker.
Has anyone done this and if so, is this basicaly a routine plug in
the proper connections, to the PCM and its a go , or
Do the individual sensors need to be OEM for the 91 only," My first guess"
Any direction here will be appreciated,, essentially save me from myself
in making a bad decision
to get a nice old XJ back in service.
THanks,
