2.0L Blown at 87K

[swampflyer]

I simply refuse to buy vehicles with these small displacement turbo engines. There is no way they can last a reasonable 150k+ miles given the weight of the vehicle, all the internal stresses, combined with the type of use we but them through Jeeping. Low speeds, idling, then high speeds in high ambient. These is only so much surface area you can give a four cyl engine to disperse the loads. And, oh yes, let’s put 40s on the rig, too. Fergetit!

Maybe the jeep 2.0 but not all small displacement turbo engines are the same. I had a 4 cylinder turbo all original engine and turbo was going strong when I traded it off on a new vehicle. It was 26 years old and I drove the heck out of it. Total miles were 172,000.

Yes, It can be when you can't do the work. I on the other hand can, But its going to cost you nearly that much for a new 2.0 too

Not even close. With an LS swap you’re looking at the price to obtain and build a good engine, plus wiring, transmission, transfer case and or adapters, mount adapters, programming, the inevitable nightmare of software not working, loss of oem features, labor isn’t even half of it.

I am currently building an LS3, that shit adds up quick and I don’t pay myself labor.

It must be a regional thing. There are tons of people on this forum that think 100k is high mileage. 250-300k is pretty much the standard here, and small turbo engines from all makes and models have been doing just fine.

What is the likelihood of swapping out a 2.0T for the 3.6?

Chrysler made one of the best 4cyl turbo engines ever made- the a853 (neon SRT-4 and PT GT turbo).. Cast iron block, port injection, simpler air to air intercooler, mitsubishi oil and water cooled turbo.

I had a modded one with 247k on it that was beat mercilessly everyday of it's life. Didn't burn a drop of oil, and still had great compression and power when I sold it. 300whp and over 30mpg.

The fiat 2.0 is not that guy.

We still have my wife's 2003 PT Turbo. I gave up my SRT-4 so my wife could have a Pink Panther 2010 Challenger. That we still have. See a trend here? Happy Wife, Happy Life! lol

Just installed them myself…

Looks nice! It seems like you did a good job!

My guess is that mopar won't pay for anything that isn't necessary. Even if it saved $ they probably keep the 2.0.

Back in the 80s I was in charge of sourcing vehicles for regional travel for my employer. I purchased many Chrysler products with a 2.5 L turbo. They would typically run for 175,000 miles before they became problematic. (Not engine related…just everything else). Just saying a turbo can last if designed appropriately. Admittedly the Wrangler is heavy and the 2.0 is tuned for high output; both of which add stress to an engine. It’s also a Stellantis product which means it’s been value engineered to be a cheap as possible….while lasting just long enough to get past warranty. I knew this when I made the purchase and I plan to sell at the five year point.

Once a head gasket has been replaced I never keep a car very long…repeat failure is likely unless the repair is done perfectly. Often gaskets fail because of a warped head. If the underlying problem/design flaw still exists, the head will warp again.

while I like the performance of the 2.0, the v6 is probably the motor to choose if longevity is important.

To clarify, my question was whether or not it is possible mechanically to replace a blown 2.0 engine with a 3.6...

My guess is that it is possible but that the transmission would have to have an adapter of some sort or be changed along with the ECM being programmed differently

Dealer finally calls today and says - cause of head gasket was bad turbo assembly - has also ruined the catalytic converter and that will need to be replaced. I said isn't that covered as damage from a covered component? They said no. I hung up and pull up contract. Sure enough it says, "Not covered unless damage was caused by failure of a covered component". Incompetent!

To all the guys mentioning it gets too hot have you done anything to allow for better airflow? Opening the top hood vents or removing/replacing inner fenders for something breathable? I also have a 18 2.0 nearing 40k and I’ve opened my hood vents seems to help some during the summer.

I had plans to mod my plastic vents, but I like the aluminum ones Motobilt came out with a few months back. No longer being in Texas and putting far less mileage on my Jeep has knocked this down the priorities list quite a bit for me.

Seems heat reduction from opening the vents is mostly anecdotal. There's a ton of threads on it, but I don't know how it could really hurt, especially at idle or off-roading. Plus, my compressor is under the hood, so keeping that cooler is another benefit.

We just posted up some test results of our H.E.R.O. Hood using a 20 turbo as our test mule that might be of some interest here:

your data and testing looks promising but Looking at your data, I see temp points of reference as "engine Bay" and "intake" but what effect did these temp points have on coolant temp?

Coolant temp is unaffected in our testing. Factory programming is designed to run at an optimal coolant temp and nothing external is going to affect the Jeep from trying to reach that specified temperature.

 

[Rogersocal]

ok, so for me doing this would be more to control engine temps and limit the above 200 degree constant and 230 spikes. This is the issue more of us 2.0's are having and are looking for ways to solve.
