1990 XJ 4.0 swap - compatibility, goodies, etc.
My 1990 XJ's engine has lost compression on #6 (30psi) and my oil pressure isn't what it should be, so it's time for a rebuild. I'm looking for a donor engine so I can still drive my XJ if necessary while I build the new motor.
From what I have found on this forum, any XJ or ZJ engine through 1999 will work with my Renix as long as I retain my flex plate, intake/exhaust manifold, distributor, etc. Is this right?
Since I will be doing the rebuild myself, is there anything I should do (or shouldn't do) while I am at it?
I am considering boring it, aluminum pistons, bumping up the compression, cam, etc. Nothing too radical - just want a little more oomph. This vehicle is basically my daily driver with very little off-road activity. Any suggestions or advice would be appreciated. Thanks!
