Can anything be done to improve performance of the 2.5 ? This is a 96 XJ and its stock. Im brand new at this so pardon my ignorance. Can it be replaced with a 4.0 ?
Yes it can be replaced by a 4.0. Anything is possible given enough money and time D). I have also heard more than once though, that depending on availability of XJ's in your area, you might come out ahead to just sell the one you have and find one with the components and parts you want.unclemonte said:Can anything be done to improve performance of the 2.5 ?

I loved my 2.5L and its 25+mpg, but here in the mountains, it simply didn't have the lungs for the passes. I never was at a loss for power on the trails. I do know that when I went to the stroker, I sure started busting a lot more axles. I lost 2 within 10 minutes of eachother on simple obstacles.
