    I have been looking to upgrade my jeeping experience. I want to sell my '95 Cherokee and get a Rubicon. My problem is I know and take care of my current engine (inline-6cyl) so well, that I was hoping to pull it and put it in a Rubicon. I also know that mechanically the inline design has certain advantages over the V-cyl design, like torque and gas econ.

    Is this a realistic swap or should I just get used to the idea of driving a the V-cyl??

    Welcome! The new 3.6 has more Hp and Torque than the 4.0 inline 6, so it might not be an issue.

    I have some more research and budgeting to do, I'm not sure I'll be getting a Rubicon newer than 2012. What year did they start to make the 3.6?

    2012 was the first year for the 3.6

    Look at this carefully. You are heading in an expensive direction with little, if any, benefit. The 3.8l has more horsepower, more torque and is considerably lighter than the 4.0l IL6. It is also much shorter. 9.2 inches shorter---which will be important when you try to stuff that 4.0l into that space. Computer problems are going to be rough.

    I suggest trying to get the 3.6. Everyone forgets it is not JUST the 3.6 that makes the difference. The gear ratios in the newer auto tranny are also considerably lower in the 12+ models. The 3.8 did great for me off-road and was VERY controllable. Just had to live with not doing 80 over the passes. Hell, if you come up with a spare $3.5k to $5k stick a supercharger under the hood and start ticking off stock Mustangs.

    JMHO...

    Not to mention the fuel mileage is better in the v6 over the I6. My thoughts are if your going to go to all of that time and money to do the swap, I'd get a v8 for the price of a supercharger. I see a lot of people selling superchargers off of their jeeps. I haven't seen one person selling their LS1,2,3 or Hemi out of their jeep. Really though, get the Rubicon, get its stance like you want, and then see if you still want to swap a motor in.

    Thank you all. Truth is I can do the swap myself without having to pay to have it done, so I wouldn't be looking at problems with it being financially worth it. But, if my biggest reasons for wanting to keep the inline have been made obsolete by the new V-cyl design, perhaps I will just leave it alone. Again thanks, very helpful!

    Look into the RIPP supercharger for the 2012+. The power gains are pretty amazing
