V6 versus 2.0L V4 updates?

[mwilk012]

Can the 3.6 hold up to a Supercharger or Turbo kit?

Define “hold up”? It can be done, doesn’t seem like the tune has been 100% nailed by anyone yet. The engines don’t last nearly as long, obviously.

I wasn't sure if any of the kits and thier tunes were nailed 100% , thats good to know. Ive heard off and on these were built sturdy by factory for possible forced induction in the future but I wasnt sold on that rumour.

I have the 3.6 as I wanted the manual 6-speed. I have had zero issues on my 3.6 over 103,000 miles. I off-road and pull a trailer.

Both engines seem to perform as expected. As mentioned the plastic oil cooler housing is a known failure point on the 3.6 and I replaced mine with the Dorman aluminum version prior to any failure. Check the torque on the 2.0 water pump bolts.

I've got 125k on my 2018 JL I bought new with the 2.0 Turbo. Zero issues from the motor. I would buy it again in a heartbeat.

Ran the normal 3.6L eddelbrock kit on my 2016 JK for 25000 trouble free miles before it ended up being stolen.

Actually, the small overflow tank has a tendency to leak when you used the included bolt to secure it. After two replacements I ended up just ziptieing it to the mounting post and it was fine since. No drivability issues whatsoever over the length of owning it.

Both seem to be good motors at this point, but they drive differently. I went 3.6, but if I was at altitude i would have gone turbo.

Drive both, and see which you like. Any motor can have issues down the road... just pick what you enjoy driving.

I just saw this when the thread got bumped. This can't be everyone's experience....? On long trips, I get 24+ mpg regularly.....

In practice the only time I experienced poor mileage was loaded to the gills and towing an enclosed trailer full of motorcycles into a crosswind. That "poor mileage" was comparable to my 5.3 GMC Sierra Crew Cab Z71 under the same conditions. In daily driving the 2.0 gave me awesome mileage. The last time I had mileage like that was in the early '80's with my Celica GT.

With nearly 2K on my 2023 Rubicon, 3.6 etorque, the only rub for me is getting over the difference in fuel economy. I write that off to different gearing and tires. Honestly, I don't mind but the wife sure tells me how much she misses the 2.0 mileage. Don't care - love the Rubicon!

so how was it replacing the plastic with aluminum? Easy enough to do?

Yesterday I ran down to the Valley and back from Prescott area. Got 25.3 avg mpg....

Plenty of threads/vids on this. Its no difference time wise, it just replaces it. The cooler itself is easy its just pulling everything else apart to get to it.

Thanks - I had a feeling it was more about getting access to the part, not the actual replacement. Just happy it isn’t a timing cover replacement. Wow!

When people say altitude what kind of altitude are we talking to see the benefits. I live in NC and will be doing most of my wheeling in the NC mountains which should be 4-6k feet above sea level I believe. Looking to buy my first wrangler this year. Thanks.

If this thread is going to stick around for a few years, will someone change the title so it doesn’t say “V4”?

 

[Deleted member 59498]

I was honestly wondering what V4 meant but didn't really want to ask.

haha I immediately thought wait… is there a 4th gen of my engine I didn’t know about?
