'11 engine vs '12 engine

Hi all...

I just bought a '11 Wrangler Sahara Extended. Unfortunately, I did not do a whole lot of research on it before I bought it because I didnt think I was looking for one until I drove it. Not to mention I always wanted one.

Anyways, I had it down to a 11 Sahara and a 12 plain extended. The '12 was 10k more than I paid for the '11. I am not overly concerned with gas mileage because I am looking for off road capability out of the box. Though, I am wondering if the differences in engine and tyranny would have been worth the extra 10k... I know gas savings alone over the life of the Jeep will probably even it out.

Is the engine and performance night and day between the two? Can 10k in the aftermarket give the 11 a little more umph...

Whaddya guys think... did I hose myself?

It is a huge difference between the engines however I don't think it's a 10k difference, or even a 5k difference. I'm sure you got a pretty good deal on that 11 with the 12's selling like crazy.

Good Lord.

As to whether the "umph" is worth it, go test drive a 2012 and decide. We can't tell you. For the most part, folks with 2012s will say it's absolutely worth it, night and day, could never go back, blah blah. Folks with pre-2012s will tell you it's not that big a deal, there's very little difference in the dynos below 4k RPMs, it's more about the new auto transmission, blah blah. You need to go drive one.

Can you spend $10k and get more performance out of your 2011 than you would get out of a stock 2012? Yes, but it'll come at the cost of your warranty. You can spend $5k and get a Ripp supercharger. That will put out quite a bit more power than a 2012--near Hemi numbers.

Ripp's reputation is excellent and there are many Ripped jeeps with tens of thousands of miles. That said, supercharging your engine will be a basis for Chrysler to deny any engine-based warranty claims, so you need to understand you'll be on your own there.

Of course, if you saved $10k by going with the 2011, spend $6k to supercharge it, then you're $4k ahead unless and until you have to pay for an engine repair of some sort that would've otherwise been covered under warranty. Even if you end up blowing $2k on such an engine repair, you're still ahead.

Freedom from tyranny cannot be measured monetarily.

As for your choice of Jeep YM, you're fine. Only place you might have regrets is if you plan on running 35" tires...more of a need to regear w/the '11 than with the '12 (though both would probably need it, so don't beat yourself up on that score, either). But both are extremely off-road capable right off the lot. And you can run both with no top and doors.

Enjoy!

10K I guess you mean for a same spec model. Having driven both I had no hesistation going with the 12 I have the 6 sp manual with 3.73 gears very impressive.

I drove them both...

What I wish I could have done is driven them both through a mud pit in 4 low. The jeep website says 40 more hp and 10 percent more torque. I don't need more highway "umph" it hardly holds a stick to my old BMW and barely does 80 with grace.

In the mud. I think the torque would matter. However, 10 percent increase? Is the difference even discernible?

Get a winch, pronto.

I really don't think you'll notice much difference in 4lo going through a mudhole.

Off road wise don't stress it. Not much a difference in low end torque.

As for this part, I wouldn't even mess with the engine (unless you've got the coin to drop in a hemi, or a supercharger). CAI, exhaust upgrades, etc are generally crap on the Wrangler.

The basic problem with the 3.8L Jeeps is that they're undergeared. If you plan on running big tires, it's worth spending the $$ to regear so you can use OD (or 6th gear on a manual) on the freeway. Other than that, I'd leave it alone.

The "extended" is the unlimited or 4 Dr. Sometimes its also referred to as the JKU. Did you get the auto? That's where the biggest difference is, especially at high altitude, towing, or adding larger tires. The 12 not only got a new engine, it got a new auto trans.

for 10 grand, the engine is not worth it. don't look back. figure what you want to do and regear as needed. you will still have saved 7500.00 if your regearing is 2500.00. check with jimbox on his regear.

If you don't have a 12 then all you can do is say its no big deal. I drive my 12 like its a freakin sport car because its as close to one as a brick can get. The reason the 11s are selling for so much less is because 85 more hp, almost 1/3 more hp in the 12 can't even compare. It is night and day different so if you saved a ton of money going with an 11, great. If you paid the same, that sucks but at least you still own a jeep!

The '10 should do just very well off-road. But there's no competition between the two on-road. I know about the dyno and 4,000 rpm and all that. But, for years, JK owners complained to me about their sluggish engine on-road. I have yet to hear a single JK '12 owner do the same. My installer (who's owned or driven scores of pre-12 Jeeps) first drove a '12 today (mine) after putting all this stuff on: http://www.wranglerforum.com/f33/jk-...ds-151822.html. I have 3.73 gears. And he said "Holy ***, what a difference! I thought you might have to regear with the 35s, but no way." I bet Jeep Hemi conversion sales drop off for '12+ models. Not that the Hemi wouldn't be an improvement, but a less-needed one foro commuters.

What's the difference in stock 1/4 mile times or 0-60 times? That should answer the question about on-road performance without too much unnecessary nuance.

Some year soon, Jeep will upgrade the JK further with something that is superior to the 2012 (whether the engine, 30-speed transmission, both, or other things) that will make me want one over mine. I won't buy one for years, as I now am heavily invested in mods. But I won't be claiming that it isn't a significant improvement if it is.

That is, unless mine catches on fire and burns to the ground, like they all apparently do now.

what is so great about this post is that even though the 2011 is a fat, confused hamster and the 2012 is rep'd by the muscle squirrel, both engines are basically very small animals!

Love it!

The only people that really complain are in the pre-12 auto transmission Jeeps. The manual crowd seems happy still. The biggest improvement is in the gearing in the new slush box.

I don't doubt that. As far as complaining goes, I don't recall the transmission component for each person complaining. But my installer has ran/owned his own big shop for years (it's almost unanimously considered the best in N. Virginia) and has driven coutnless of customer Jeeps after his crews work on them and modify or build them up. These have to include some pre-12 autos. I'm seriously not joking, he was surprised. I think he thought I had been exaggerating a bit when I said I had power to spare with the 35s he had previously installed. He said that there is no way he would regear with my set up (3.73s/35s), but would always have done so with an '06-'11 with 35s. And he's not buttering me up. He quickly shoots me down when I suggest something unwise. And he knows he would make a bunch of money if I decided to regear (I have given him all my business, and he is very attentive).

That 2012 got so far ahead of the 2011, so fast, you can't even hear its engine ticking.

The guy in the 2012 probobly didn't have a chance to smell the oil burning in the 2011, either.

Hey, you've got to have a sense of humor if you're gonna own a Jeep

Ok, the 2012 has more horsepower and torque. Doesn't make me any less happy with my 2011.

Haven't even test driven a 12. So right now.....in my head.....my 09 3.8 is the fastest, highest torque producing MoFo on planet earth! That, and my hamster doesn't tick and it's almost paid off.

Good find. I've owned both, but about 14 months in between. I thought there was a lot of difference, that illustrates it nicely.
