Issues with 2.0L Turbo

[yokramer]

When comparing the jeep turbo 4 engine to that of Alpha Romeo is ludicrous. If it were the same engine jeep would have a larger oil pan or require 3,000 mile oil changes. No forged crank and pistons. I would safely say heads and intake are different as well. Almost as different like the 1st Gen Pentastar 3 6L and the 2nd Gen Pentastars in our jeeps.

In terms of differences the Alfa Romeo 2.0T has a SOHC cylinder head that uses MultiAir whereas the Jeep 2.0T is DOHC with a traditional dual VVT. The Alfa Romeo 2.0T has a forged crankshaft, whereas the Jeep 2.0T has forged rods.

I have a 2021 Wrangler Rubicon and a 2021 Alfa Romeo Stelvio and from an appearance standpoint and name standpoint they are the exact same engine and transmission. Turbo located in the exact same spot, same intake manifold, 5.5 qts oil in the engine (vs. Jeep 5qts) The difference comes in the tune. When I'm in Dynamic mode in the Alfa it is a little rocket ship and obviously I don't get that in the Jeep. However I feel the 2.0 in the Jeep gets the job done and I'm basing that on running a 3.5" lift on 38s and still running 4.10 gears and this thing still jumps off the line for its size.

Again this is just wrong information, the turbo has 0 problems when crawling and isnt all over the place. At no point have I ever felt the engine was making too little or too much power due to the amount of boost it is producing on any trail from dirt roads to 7 rated trails. On slick rock or east coast red clay mud fest. Or just cruising around town at sea level or boming through the 10k feet passes in the Rockies.

I get you are scared of a turbo but dont let your bias get in the way of good information.

My first turbo was a 1991 Plymouth Laser with a 2.0L. Fun little car to have when you are single. There have been various other turbos in my life since then, both diesel and gas, so I am no stranger to them.

I wanted to order a 3.0 but it was discontinued, so I looked at what was available. The 392 was out - too expensive. That left two choices. I rented a 2.0 while on vacation. It was peppier than the 3.6 and the lag was much less noticeable, but it was still there. It also had to be in boost a lot more to get things moving.

Under light partial throttle, the amount of boost would change and produce a non-linear throttle response. That is a difference from the 3.6.

You guys are reading way too much into my comment. I never said you would have problems, or the 2.0 wasn’t up to the job. The 2.0 and the 3.6 are barely adequate. They were designed for lighter vehicles that had much more efficient drivelines as well.

The base engine in the Wrangler should have HP/TQ levels like the 3.0 to make up for the extra weight and inefficient driveline. This is why so many people would love to see the 5.7 in the lineup.

Like I said... most can't tell the differences between Gen 1 Pentastar and Gen 2 Pentastar. Probably the same for the 2.0L. You should look up Guila turbo 2.0 issues with oiling. Your jeep is not immune. Alpha Romeo only offers a larger oil pan as the bandaid they for an issue they cannot fix. Just pointing out what most here ignore on both V6 and Turbo 4. The Jeep 3.5L v6 is not the Pentastar you're looking for. The turbo 4 is not the Guila engine you're looking for. But because both Alpha Romeo and Jeep use DI, fuel contamination in oil will happen. That is known by your Alpha Romeo service tech.

Please let me know any issues that you have experienced with the 2.0L Turbo or have read about that may be chronic with it. I am considering a new Wrangler and don’t know if I truly want this powertrain.

I have 70947 miles on my 2.0 Turbo Sahara and have not has any issues at all. So far it has been great and the gas milage is 20-21 around town and up to 23-24 on highway. However, around 25 degrees, milage drops to about 18-19.
It is a bit noisy on cold start, but as it warms up it quiets down.

Wife loves her 2.0T 2020 JLU Bikini Blue. She fell in love with the Jeep/Color driving by it at the dealership going to get service on my RAM. Now @ 103K miles, Performing all services on time, Timing chain cover leaks a little oil. Not enough to change it out yet. Turbo still gets her down the road and between us we can vary by 3/5 mpg. She has a heaver lead foot than I do. We run the 87 fuel most of the time and do just fine. We step up to 91 on longer dedicated Jeep trips, Winrock, TN in 2021 and Moab this year. You can tell the difference and read all about which Octane is better when. We have been happy enough with how she uses it to stay with the lower octane for the way/type she drives. The folks here on the forum have lots to share. I am very happy the one she chose had the 2.0T. She's had mostly turbos, fords, Pontiac, Chrysler after Highschool so nothing new in the way it performed.

After all the comments on the forum about the 3.6, we were even happier God gave her the 2.0T.
Our previous Jeep experience with the older 6 cylinder inline 76-CJ5, 86-CJ8, we have been very happy with this one. Our other two 2021 JlU and JT Rubicons have the 3.0 diesel. I love them. She tolerates them. (they at least have a turbo too) Snazzy1, our newest to us (the gladiator) is the "Our's" Jeep. So we each have a JLU and WE have a Gladiator.

Jeep addiction is a real life experience. LOL!

Which ever you get, it will be an Adventure!

Oh yeah, there's this little distinction as well. To realize the torque advantage of the 2.0T, you need to use premium fuel. Otherwise it's a weaker powertrain overall. And works harder. And has very hot and very fast spinning parts requiring more oil frequent changes.

That being said, the lower torque delivery of the 2.0T makes the heavier JL's move quicker off the line and feels more powerful than the 3.6L..

4.10 and 38s and it jumps of the line? I have 37s and 4.56 gears and I would definitely say its not jumping off anything.

Yep. I have no reason to lie, just telling you my experience. And also put it in perspective... I'm talking about a 5,500 pound vehicle jumping off the line... not a corvette. IMO it moves quickly and jumps off the line.

Love my 2020 2.0, although I did have tranny failure with it at 40600 mi after 5yrs. Chrysler replaced it with brand new tranny which was covered by my Mopar extended warranty. Majority of car companies now have their own version of a 2.0/turbo charged engines...4cylinder engines/turbo are way way better now than 10yrs ago. They pretty much go faster/and fuel efficient now than before. I would only suggest with your jeep, just get their Mopar extended warranty. After that tranny issue I still love my jeep.

Does anyone have any information on if the 2.0t EVO will be making it into the Wrangler for the 26 or 27 MY ?

So far, no info. As others have said before, it is doubtful it will show up until the next generation of Wrangler comes out.

That would be upsetting.

Both are high strung motors. Both run hot. Both tend to deal with minor leaks, especially coolant and oil reservoirs/housings/lines.

Anyone saying either motor is "100% perfect" or "an absolute piece shit" is full of shit themselves.

Both are generally reliable. The 3.6L's been put in well over 1m different Stellantis makes and models. Use good oil and gas, don't baby it (some of y'all baby your Jeeps and don't understand that you do, in fact, need to actually give your motor WOT on the on-ramp, every once in awhile), and it'll run fine for ~200,000+ miles.

The 2.0L turbo is impressive for its size vs. power. If you want to do a lot of wheeling, it will run uncomfortably hot. Compressor bearings can suffer from a short lifespan. It needs premium fuel, period. Really the only drawback.
