So Honduras, how hard of a swap was it??
He has been gone for years, sold off the project
More interested to see the rest of the how-to....
Some on LOST but no one place has the full story, had to of followed along during his build time
Thoughts on a stand alone ecu and LS swap?
Not worth the hassle
If no swap has been completed by now there won’t be one.
After you do a SFA, of course stronger transmission, rebuild / upgrade transfer case and other items , then start trying/ doing your LS swap
I wouldn't be surprised if something similar to an LS level swap would torque the entire subframe/body and twist it permanently.
Kind of like too much engine on a small airframe airplane... not designed to handle those stresses and it will just flex and twist, resulting in failures elsewhere.
only swap I see as being worth the hassle is the 2.4L turbo motor swap.
The KJ's structure is 300% stiffer then the XJ's,SFA'd and at full stuff I still could easily open and close every single door(no twisting at all).
That's reassuring. And I'm sure others have stuffed 400hp engines into XJ's before successfully, so the KJ body structure should handle it as well...
Not that I really need it to, as I plan to retain the stock powertrain myself.
I know of 1 KJ with 500+HP(modded 6.1 HEMI),was professionally built and was shipped outside of the US,the owner wanted it all hush,hush so your not going to find much about it.It was SFA'd also,the only way to properly fit a V8 into a KJ.
Well, when you can afford to have such a thing professionally built and modified, then shipped across the globe, you can do pretty much whatever you want.
But that just goes to support what we've been telling everyone who ever posted "how can I swap X motor into my KJ?" ... you can swap in pretty much whatever the heck you want.. if you can afford it.
From what I've seen over the years, a SFA'd KJ performs very very well. Makes me wonder what if- if the KJ had been equipped as such in production.
Probably was purposely not SFA in order to not take away from prospective Wrangler buyers.
currently working a 5.3L LS for mine, easier now that the factory trans died and I have a different vehicle to drive. Won't have to worry about SFA since it's RWD. Won't be able to do much work on it due to minimal garage space, though i should have the engine rebuild done by spring, possibly the trans as well.
