Hello Fellow Jeep Enthusiasts,

I want swap my 2.0L 4 cylinder eTorque turbo (38,000miles...good condition) Hurricane for a 3.6L Etorque Penastar engine. I have the 8 speed automatic so I think it would be a direct fit? I live in Eugene, OR, My questions are:

1)How much would this cost?
2) How difficult of a job is this to do?
3) Where can I get a new or fairly new Pentastar Etorque 3.6L VVT engine?
4) Could this be done myself or better to have a mechanic do the work?

The 2.0L turbo works just fine, I rather have a 6 cylinder for my own peace of mind. The turbo, I do not think will last as long as the V6 Pentastar. Already I find I have to change my spark plugs every 30,000 Miles and change oil according to a "severe duty" schedule (every 3000-4000 miles) because the turbo is hard on the engine. How long do these turbos last? I do not feel confident about them. I got this engine because of slightly better gas mileage but I feel I made a mistake. Can someone guide me please?

thanks

Michael

I honestly feel like you are better off trading it in and getting the jeep that you want.

Why do you have to change your oil every 3-4K miles? Is this based on the Jeep’s maintenance indicator, actual lab testing of the used oil, or something else? What prompted you to change the spark plugs? What are you primarily using your Jeep for?

You could do a lot of maintenance on your existing engine for the cost of swapping it out. I agree with RubiChick that trading your Jeep for a new or similarly used Jeep with a 3.6 would be a better option, unless you have made mods to your Jeep.

I made mods to my Jeep in that I installed a dual battery system, an immobilizer, a propane tank off the side of the roof in the back. I could undo most of those changes and bring it back to stock. It might make the most sense to trade it in I guess. For the 2.0L turbo I read its suggested to change it using the "severe duty" schedule because the turbo is hard on the oil. Plugs are suggested every 30,000 miles for the same reason and frankly I read online that the turbo just doesnt last as long as the 3.6L V6. I use my jeep for everything. Commuting and also off road. The last thing I want is for the turbo to breakdown in the wilderness with no service. The 3.6L seem to go almost twice as far in terms of mileage. I read these turbo motors last about 100K where the 3.6L lasts at least 200K.

The 3.6L seems simpler and more reliable. Your thoughts? Anyone's thoughts? thanks

Someone once said to me, if you want a better performing motorcycles, buy a better performing motorcycle - sell it and buy what you want. I'd keep what you had, and keep your maintenance schedule as well. I do my oil at 5k, then the other things around the recommended times. Let the clowns that say different say what they want, another bit of advice, "Your opinion of me is none of my business", ie: do what you want, and ignore what people say about it.

I think you are being paranoid. Unless you have an oil analysis that shows your oil needs changed at 3k miles, follow a normal maintenance schedule and drive the 2.0T until it dies. When it dies, fix it or swap it out for 3.6 then. Making the swap now is just spending money to fix something that isn’t broke. Will you even keep the Jeep til it has 200k miles on it? Even if that’s your plan now, things change. You may be spending several thousand dollars that actually reduces the resale value of the vehicle to install an engine that MAY last the next owner longer. I say reduce the value because now you’ve got a vehicle with a mismatched engine and I personally would question why the motor was swapped if I were looking at buying it.

The best thing you can do for a turbo charged engine is to make sure you allow it to idle for a minute before shutting it down. This allows the turbo to cool a bit, and heat is a turbo’s worst enemy.

As to reliability, I don’t know how the 2.0T will hold up in the Jeeps long term, but the 3.6 has its own set of issues. From heads to oil cooler housings to cam position sensors to cooling system issues to unexplained misfire codes… the list goes on. The 3.6 has been around 6 years longer than the 2.0T, but I have read about a lot more 3.6 issues (many of which occurred at low mileage) than I have 2.0T issues.

I don’t think the JL 3.6 has the same issues with the heads and oil cooler. If it does I have not seen it pop up here.
It seems relatively trouble free compared to the JK.

Maybe I have not been paying attention.

I think you need to read the maintenance schedule in your owner's manual again. We have a 2020 JLU with the 2.0T and the maintenance schedule says to replace the plugs initially at 60,000 miles, not every 30,000. Also, severe duty use is defined by the following below. It has nothing to do with the fact that it is a turbo. I change the oil every 5k miles in ours as well as a 5 tire rotation at that time.

Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off road environment or
is operated predominately at idle or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.

Actually the 3.6 in the JL is not the same engine that was in the JL. The 3.6 Pug engine in the JL has not had the head and sensor issues of the JK. Although they do share the same oil cooler system.

^ This!

One of the key benefits of owning a Jeep Wrangler is its spectacular resale. Might as well take advantage of it.

Swapping motors is going to cost a fortune, produce one million unintended consequences, and you will never get that money back.

if it ain't broke, don't fix it... if it breaks then try putting in any engine you want

Frankly, i would trade /sell as it is and rebuild and modify the new one.. it's half the fun of a jeep anyway


and it's not my money which makes all this advice really easy...

 

[broomiejkwrangler]

Yeah I think you're overthinking this entire thing... But if you're THAT concerned over the 2.0T engine, just strip off the mods and sell it and buy another one with the 3.6L V6 engine... I would not monkey around swapping motors this early in the life of the vehicle.

I'd think you would have no problem selling it out-right or trading it in for another Wrangler. Only catch I could see if it's something off the wall on options maybe.
