ok dont get mad iv read like 5 hours work of threads about sawping HO into renix

so my question is this i own a 91 xj 2wd with 76,xxx miles and i just bought a 90 xj 4x4 with a blown motor so im going to use my engine. Now can i use the Renix intake and fule rail and use my 91 injectors on the renix intake or would i have to use the 91 intake and injector rail and just try to get the renix tps to fit in the 91 throttle body and mess with the rail fuel line im 19 and becoming a GM certified tech so this isnt a challenge im just confused

 

Perhaps u can explain why? U want to put your engine in the renix jeep?

 

well the renix jeep that i bought has a blown 4.o motor (rod bearing went bad) and i have a 1991 with the 4.0 with 76,xxx miles and is in good shape but the body is bad and also 2wd and the renix is rust free and is 4x4 so that is why im swaping the 91 motor to the renix i know it possible and iv read very helpful post but i just have some additional questions now im not swaping the engine harness im just swaping engine block and head as a unit

 

keep the renix manifold and I believe u may have to gasket match the ports on both sides (head and intake)

 

Can I used the HO injectors in the manifold of the renix

 

yes I think so

 

Let's keep this simple and to the point.

Cruiser’s HO into Renix Swap

This swap is easier than some will lead you to believe, generally those who have never done it. Those of us who have done it, like myself, will share with you the things that need to be done for a successful swap. Just think of it as swapping in a long block.

The HO and Renix have some differences but none that can’t be overcome very easily.

Any HO engine from an XJ or ZJ through 1999 can be used. One running change was that the rear of the head was no longer drilled and tapped for the temperature gauge sender beginning in the 96 model year. The sender can be relocated to the threaded hole in the thermostat housing taken from the HO engine. You’ll have to extend the wire to that location. Some brave souls even drill and tap the HO head for the sender.

You will be using the intake and exhaust manifolds from your Renix, along with all your sensors and wiring. Since the intake ports of the HO are slightly different, you use the Renix gasket. Exhaust ports are identical.
You will need to use your Renix distributor as it is different than the HO because they use different fuel management systems. The flywheel or flexplate from the Renix must be used so your CPS gets the correct signals. The valve cover from the Renix allows you to keep your CCV system intact and requires no modifications.

The HO block will have a plug in the coolant galley on the driver’s side of the block, closest to the front, which needs to be removed so your Coolant Temp Sensor can be installed in it’s place just as it is on the Renix. It requires a 5/16” square drive or a modified 3/8” drive that has been ground down to fit. Do this before installing the engine.

As for the knock sensor, which is located just above the oil pan on the driver’s side of the engine about mid way, all the blocks I’ve seen are threaded for it. If not, I’ve heard they may be drilled but not tapped. Tap the hole if that’s the case.

That's excellent info!

 

thanks i really appreciate it guys sorry about this i know there is tons of threads out there for this topic just needed some updates i should be doing the swap within this month so if i have any questions i will post here

 

I wanna see a build thread.

 

You've not seen that before?

 

yeah I saw that plenty of times, I just wanted to compliment you. Lol

 

I have a quick question and if you can send me the link because I cant seem to find it but how do you set up the lower "footer" or what ever you call it that you can put links like xjwonders to his builds so I can make a link to do the same
