New Jeep 2.0T Hurricane 4 has complex tech [Engineering Explained]

Did I say they were interchangeable?
Don’t think so, all I ever said was look at the directions and the fact that a different tool is needed for the pre and main combustion chamber. What makes you think that the spark plug requirements would be the same.
Because on a HEMI they are?

Huh ?

You have called a wrong number
OK, you hung up and redialed

Per ChatGPT, the Shelby trim was 1989 only and came with the 318 but was not available as a convertible.

The convertible option was available from 89 to 91 and only came with the V6.

But that means the parts for an easy V8 swap could be available

Sure does!

There is a 4x2 Dakota Sport convertible in Florida for sale right now. $13.5k, which I think is a little high priced, but they are still out there.

There seems to be a resurgence of 90’s and 2000’s vehicles on the market lately. More and more people are getting sick of all the complicated (hard to repair) digital crap. Myself included.

No, you didn't say they were interchangable. You said the opposite: "Probably wouldn't fit", which is bullshit since there's severe warnings for erroneously putting them in the wrong place.

They're very much interchangable from a "does it fit" perspective, which makes the design incredibly dangerous.

I said that the SOCKET wouldn’t fit.
I guess you could screw the small ones into the larger holes but good friggen luck screwing the others in. Maybe You could do it, that is then the reason for the caution.
Do you own any calipers or a micrometer?
Do you have a 16mm and a 14mm deep socket?
If so, measure the diameter of each, chances are the 16 is bigger than the 14.
Do you think that the spark plugs are just sitting on top of the cylinder head?
My money says that they are down inside a bore that is just large enough for the Socket to go in.
Rocket science, not really.

Not so much for us, these JO’s wouldn’t even pass “Leno’s Law” to exempt 30 YO classics with obsolete difficult or impossible to find smog parts to keep them on the road. … it’s 75 down.
Even my bought new 95 Dodge 2500 was in jeopardy of becoming scrap iron a few years ago due to an “obsolete” ignition control module. It took a couple months of searching to find one in a Colorado junkyard.

My best vehicles have been Mopar. My Ram needed a water pump once. 10 years and over 100K miles, it’s still on original brakes.

I must be lucky, but we’ve had the best luck with them, even the wife’s Caravan back when the kid was playing soccer (20 years ago) was extremely dependable.

I see those same lists, but have never had those results from Mopar. It’s all we own.

I'd jump in about here and brag about my great experiences with GM trucks over the decades, but I see they're squirting out engines that seize after a few miles and transmissions that lock up going down the highway. Toyota engines are spinning main bearings. What's this world come to? I'm about due for a new truck, but I can't seem to rely on GM anymore, Ford EcoBusts are a bad gamble, Toyota's twin turbo V6 sounds worse. Maybe I'll just keep the 2014 truck.

Mate, time for a one way tour to Texas.

Ford Super Duty. 6.8L, simple fuel injection, simple engine, plenty of power. If you need more power, upgrade to the 7.3 version.

We've been shopping trucks a bit the last year, and this is the only one that I'd consider at this point. Just the XL version with the 6.8. Heck, it has rubber floor mats. It's the work truck people asked for. They were clearancing 2025's last November near us, discounts were down to $45K for the total price, XL's with a few options including the offroad package with rear locker. The gas 6.8 is going to net you 15-19 MPG and it has a large payload and tow capacity. Pushrod V8, cast iron block, aluminum heads. It's about as simple as you're going to get in this day and age.

I'd like to hear how Jeep is going to manage the additional heat generated with that boost and compression ratio.

On a vehicle like the JL, as opposed to say a BMW that may see track time, how long do you think these engines spend at full throttle? Like 3 seconds every 3 months? Something else?

The best I could come up with was the dudes in the middle east doing the Dubai dune climb at 110F - that is like what 5 seconds at full power? Not likely to be an issue.

I'll just be happy if they can keep this new 2.0 from sounding like a farm tractor when cold like the old one, people used to ask me if my 2020 2.0 was broken from day 1 and eventually I went back to the 3.6. It was reliable and fun though.

My 2026 does not sound like that (my 2021 did). Jeep has come up with a different calibration for the start up sequence, where they bump the RPM to nearly 2,000 and slowly bring it down. They must also have changed the high pressure fuel pump/injectors or sound insulation or something. The 2.0 is now way, way quieter and more pleasant at start up and idling than the S58 TI3.0 in my BMW M2.
