Ls swap into 2001 xj

Hello, I’m not sure if this is the right spot for it but I’m trying to get a list together for the basics that are required for an LS swap into an xj to help myself and everyone else looking to eventually do this swap. As far as is have found, it seems the easiest way to go is Novak motor mounts and exhaust, that I am willing to spend. With that being said I would like to keep the rest of the swap as simple and wallet friendly as possible. What transfer case is usually transferred in? Does it need an adapter plate? As far as the engine wiring goes do you use two harness in your jeep or merge the two into the ls harness? Are aftermarket gauges usually the way to go? Any other issues that will arrise please let me know because I am trying to educate myself on this swap.

Thanks

Re: Ls swap into 2001 xj

The transfer case is going to depend on what transmission your planning on using. You can get a trans adapter for the AW4. Do you have to deal with emissions?

Re: Ls swap into 2001 xj

I donít necessarily need emissions, depends on what route I go if I went LS (either 5.3 or 6.0) I would pair it to a 4l60e/4l80e, however if a different trans is doable and a lot less hassle I would go that route.

Re: Ls swap into 2001 xj

If your going emission's then you have to use the same trans that came with the donor vehicle. I did a LS1 swap and all emission's CA legal through a referee. I pulled all wiring from cherokee ecu and running only LS1 computer with new gauges. using 231 transfer case with adapter plate from novak too.
No emissions is heck of a lot easier but I didn't want to get a fat ticket for crossing a road with a green sticker. Motor and Trans came from a 2001 Camaro SS.

Is the 4l60e/4l80e swap hard or is it not bad as long as you keep the wiring harness/pcm/Tcm for the trans kept with the originally trans from the swap?

Re: Ls swap into 2001 xj

I also was thinking about pairing a 231c to the 4l60e and getting an SYE for the 231c? Is this the best option to retain the VSS on the transfer case?

Re: Ls swap into 2001 xj

the trans swap is pretty easy, just bolt it to the motor before you put it in the cherokee. If I have time after work today i'll take some pictures. just want to plan everything out first before you start.

Re: Ls swap into 2001 xj

I'm curious as to your objective, that's a lot of work and cost.

Get a Chevy 241C and install a JB Conversions SYE?

I assume you have the super short kit which is still easily adaptable to your current set-up.

I am not sure as to what SYE kit I have, it came with the jeep. However, wouldnít I need an SYE that has a spot for a vss or what is usually done as far as that?
