Hello all,
I am new to this site and have a few questions as my new/old 89' XJ is going under the knife tonight for a new motor..... All we are able to find around here are the new HO motors 96+ so I have researched it and researched it to see how involved this sway actually is. This is what I have so far....

Use old Intake
Use New HO Manifold and weld up new downpipe
All other sensors/senders should bolt back to the HO motor off old 4.0.
Is there anything else I need to know?

Please make sure I am on track.
Will all other componets in motor bold back up? Powersteering.. and thigns of that nature?

I will tell the story of my XJ soon I am just ready to get this thing ready for the trails.

your on the right track so far. If you want, PM 90PioSport99 and he can walk you through it. Tell him "Sir Mix Alot" sent ya...he'll treat ya real good! :D
 
must use the flexplate from the 89. the renix computer(ecu) needs the correct signal from the cps. the flexplate from a 96 and up wont work with renix ecu.
