4.0 to 4.0 HO swap
 

Can someone please help. I have a 1990 Cherokee with the Renix motor and I want to put a 1993 HO in it. I am going to change the wiring harness and ECU/PCM along with fuel lines and fuel sending unit that are from an HO. I need to know if there is anything else I need to swap over? I do not need info on swapping an HO in with the Renix manifold and wiring harness. I am doing the whole HO and wiring harness swap so do not even mention any Renix parts.
I have been searching through threads to find all the info I have now but am just covering all my bases.
I want to hear from people have DONE THE FULL SWAP ONLY PLEASE! That is the wiring harness and engine from a HO Cherokee and everything they swapped over like gauges etc.
If youre going to be a smart*** please proceed to another thread
thanks guys

Ask cruiser54

Nah. I don't swap the whole harness to HO from Renix. I do it the easy way.

ok don't ask cruiser54. Google is ur friend now.

Easy way best way. 93 HO ZJ to 4.6 Stroker. Injector adapters to 2000 intake that's it.

Here's some excellent advice to grab ahold of........NOT!!!!

Is there a problem with the engine you have now or you just want more power?

325 hp from a I6, Worked out very well for me!!

Does that mean you went and cut the lock lol

i have a 95 motor in my 90, but not the HO harness.

i don't think you can successfully switch it to HO very easily if not at all.

You can, but it's all for naught.

Do what you did, and I've done many times.

christ, I scrolled down too far by accident and necro posted.

99 XJ
 

I figured it was safer and "cleaner" for the forum to revive this thread then to start a new one on the same topic.

I've been eyeballing the net for a detailed full vacuum diagram for my 99 XJ with the 4.0. I want to get a roll of replacement tubing and just do the whole darn thing... 20 years old and if I've got a leak somewhere, well... all the rest of those plastic/rubber lines are the same age.
Anyone know where to track this down?....that is detailed enough to go off of?

Cruiser54 , I have to ask about the max size tire and rims I can put on my 96 XJ 4x4 without cutting or rubbing? I'm trying to keep my jeep stock height but more aggressive looking.

There are many threads on tire size, not sure how this one applies in any way.
