No . All YJ engines were 2.5 with injection so you should be OK get the ECU and as much wiring and sensors as possible cos you can bet the buggers changed some'at to help the planet or some Ghay shit.
Useless Piece of info........ That 2.5 with injection was also used on the last. CJs and the other CJ engine option for that year,the Carb fed 4.2 made less BHP in that guise.....
Torque thingies were a different matter of course

The 2.4 was a late. TJ engine and very few in this country.......apparently like to be turbo'd with OK effect
