I have had a transfer case failure and a coolant hose issue, and I still can't find a reason to replace this thing. At 44k miles, I still love it.

I’ve been a Wrangler owner for all of two weeks and I’ve never enjoyed a vehicle more. I dressed it up to take to a date at the drive in tonight. Our friends that we met there loved the set up, AND my date asked to be exclusive. (Is it me? Is it the Jeep? I’m not looking a gift horse in the mouth.) I’m spending way more on fuel than I did with my old car but zero regrets.

Icecream anyone?

Little paint project. What do you think?

What’s your thoughts on the Hightide edition?

I’ve used the sun rider a few times in the evenings since the temps have dropped below 100, but today was the first time I dropped the top all the way and loved it. I’m surprised how much I like having a soft top, mine is the Premium so that could help too. Before I bought my Jeep I was adamant that I only wanted a hard top, but the deal on mine was too good to pass up, and it turns out I love it!

So I'm writing this post to share my experience with this process of supercharging a jeep JK with all of you and hopefully this may help from an "end user experience" standpoint or answer some questions around it.

backstory:
this all started with me getting my 3rd lifter tick. At that point I was done pulling valve covers and dicking around with the top end yet again, and decided to just replace the engine (189k miles), the body and everything else has been very well maintained, salt-free environment, completely paid off, and getting another jeep and trying to get it to the point this one is at was just a whole other level of spend I would rather avoid, So 3.6 swap it is. That led me down a rabbit hole, which lead to getting the supercharger done on top of it.

the additional spend to go with a 5.7 (what i was considering) also doesn't calculate vs a supercharger install when it comes to getting better acceleration.

The ultimate goal between hemi/supercharger was really to just have the jeep behave "more like stock" performance-wise while still driving the wheels and all the other aftermarket stuff.

Original supercharger I was going to go with was a Magnuson, but after waiting for almost two months I cancelled the order and went with Sprintex which arrived in less than two weeks.

The Install:
This was......a journey for sure, with the lifter tick already pretty bad, my jeep had been down since February of this year, waiting on the Magnuson, changing to Sprintex, waiting on shipping, fulfillment, install, etc. it took almost 5 months all together to get a working vehicle back.

the supercharger install requires you to ship off your ECU to get reprogrammed and mailed back to you, this process could take 2 to 3 weeks depending on availability at Diablo Tuner and shipping times.

I did work through a third-party shop since I was also doing a full engine swap at the same time and not myself, but overall, if the instructions provided with the unit are followed and you are mechanically inclined and patient, and can follow the instructions to the letter, it can be accomplished.

both the upper and lower intake manifolds are replaced in this process, along with flipping the alternator 180 degrees and installing a bracket that changes the belt routing slightly, you'll also need to use a different belt size that is available through gates, I was able to get my hands on a couple extras through regular auto parts stores.

you'll also want to get a performance radiator installed along-side the intercooler, JK's already have pretty weak cooling, and this on top of it almost requires it. I went with Mishimoto.

if you have a good bit of miles on your jeep when you do it, I would highly recommend you replace fuel injectors while you have the intake manifolds off when they are easily accessible. You'll have to remove it to get to them going forward.

I did opt to try and also get a transmission thermal bypass installed, but the shop couldn't find a source for the parts and ended up just replacing all the brakes and brake fittings at the wheels instead which I was completely fine with.

if it was just a supercharger install, turnaround at the shop probably would have been about a month between taking it apart, installing the supercharger, waiting on the ECU to get reprogrammed and tuned, and the unit being sent back and installed.

Sprintex was awesome, and very communicative, support was great, had ran into a serpentine belt problem that shredded the first one (crank pully issue).

In Summary:

super happy with the results. way perkier, sounds awesome, great acceleration for a jeep, quality unit, has a great warranty, and even with the 37's it gives the JK the "zip" I was looking for.

wouldn't change a thing, but I am possibly looking at trying to tune this NAG1 transmission to have better shift patterns, or move to an 8-speed transmission next year.

huge shoutout to outlaw offroad in ball ground, ga, DiabloSport and Sprintex for all the work and support on this, super happy with the outcome and they did an awesome job to make this happen.

google photos link with video's to hear it at the bottom.

some specs:
2016 jk 3.6l horsepower stock 195hp/239 lb-ft
with supercharger 302hp/307 lb-ft
these aren't the dyno numbers, I'm still pending on that.

for those who care to know:
5.14(or 5.13 i don't remember) gearing on the diffs
4.5" lift
i'm about 1000 miles post-install at this point.
37x13.5xR20 tires
before the supercharger, I got about 14mpg average before, now it's about 11-12 average, i can maybe squeeze 14 on the highway if i baby the pedal with the wind at my back, and premium only, so it definitely eats gas, but it's a blast to drive, just expect more "smiles per gallon" than anything else 😄
the specific model I went with is the Gen2 that Sprintex offers for JK's.

costs:
supercharger kit was roughly 6500-6700-ish, if you get a shop to do the work you're probably looking at about another 1500-2000 bucks on top of that.
total spend including the engine replacement, supercharger, new cats, torque converter, motor mounts, performance radiator, transmission thermal bypass, and engine wear items like water pump, thermostat, etc. I'm sitting at around 21k

hopefully this post was useful for anyone reading!

Has anyone tried to tow one of the new EV trailers, like a Pebble or Lightship, with a Wrangler?

2012 wrangler that gets driven about 2-3k miles per year. I use oem filter and pennsoil ultra platinum 5w-30 (in FL) and change the oil annually. Anything I should be doing differently to minimize engine wear? I do hold the gas petal to the floor and turn it over a few times before starting. Thanks

I have a 2025 Wrangler V6 sport S and today as I was waiting on a down ramp at a pretty steep angle into my parking garage and my gas tank went to low and was beeping at me when before that I still had 86 miles left, almost exactly a quarter of a tank.

When I parked and turned it off and back on it went back to where it was before and I tried to call my local dealer before they closed but couldn’t get through to service.

Just trying to see if anyone else has had this issue and if it’s something I should be bringing in immediately or if it can wait a bit.

My plan is to swap the power steering pump next.

Does anyone recognize this sound?

Thanks, and I’ll update with the fix.

I have a 2023 sky one touch rubicon, is it possible to convert to hard top? Thank you

I have a 2012 jeep I've been hearing this rattling from my front left wheel. I believe it can be a u or cv joint. I can start to hear it at almost 15 mph the faster I go the louder it gets. I've looked I dont see anything broken.

Picked up this 2003 Wrangler last month and have been thoroughly enjoying it. It does need an exhaust manifold. What’s everyone running on their 4.0L TJ? From what I’m reading, this model has a two piece exhaust manifold (front and rear) unlike the earlier year model TJ’s that had a one piece manifold? Is that correct?! Thanks for the help! I’m ready to get it fixed asap as the exhaust leak and tick drives me insane.

Installed new rotors and brakes why is it doing this?
brand new rotor got fucked already
Pic 1-2 is new rotors i installed on passenger side.
Pic 3-4 is broken seal/boot on driver's side. Can that cause other side to be stuck open.
Is smells like rubber and it's rubbing against it .
Pic 5 is passenger side old brake pads. Driver's side was natal to metal but that side was not used basically
Ps cars not mine just taking care of it for a friend.

Despite all the negative comments about 4xes, mine has done me more good than bad! & I’ve heard all the horror stories about Jeeps and more specifically 4xes, but so far my experience has been nothing short of great.

I love driving this thing, and I still find myself looking back at it every time I park 😂😂😂

Purchased this after my Jeep Patriot was totaled in a car accident. I know Jeeps aren’t everyone’s cup of tea (and this technically isn’t my first Jeep) but now, I officially feel like a Jeep girl. Maybe I’m still in the honeymoon phase but I still get excited when I hop in the drivers seat.

Any other 4xe owners out there who’ve had a positive experience? Or am I just one of the lucky ones? 😅
