please dont blaze me , but im a big fan of chevy LS motors , does anyone have , or is anyone thinking about putting an LS motor in their JK , is there any kits for it , i believe the motors are lighter , not by much , than a hemi , they woulld def be more fuel efficient , any one please chime in , thanks

 

I have been thinking the same thing. I'm sure its possible but I havent seen any yet. I will have to keep my eye on this thread.

 

I'm sure there's a builder out there who can do the swap, but I'd think part of the fun would be driving it on the street and an LS motor will make it not street legal just about everywhere.

 

Plus, you'd have to re-do pretty much everything, since the computer wouldn't control any of the gauges anymore.
More hassle than it is worth. If you really need that motor, the H3SUT might fit the bill, just cut the roof off for a Jeep experience.

 

Why U say it would not b street legal?

 

Yup, this is what I was getting at.

The exceptions would be things like street rods who are emissions exempt due to their age. At that point you can stuff whatever you want under the hood.

 

This would be fun and really complicated. I believe with the right amount of time and money it can be done.

Just need a lot of both to get it done.

I thought long and hard about this swap. I have a 5.3 in my 2005 unlimited now, so not new to that conversion. But, after talking with several people, I decided I wanted to retain a few things, like factory gauges, and cruise. So, I have decided to go with the hemi.
I would live to see a ls3 in one though.

 

Smart move. I know this doesn't count, but I put a Ford 351 in my CJ and that was alot of work, and it has manual guages and everything. I can't image what it would cost to put a GM engine in a JK. Besides there are a number of install kits for the Hemi in a JK, that include everything, absolutely everything, that you need to stuff it...
