2.3 Shaping up to be the better Engine?

[mpeugeot]

Why do you say the 2.7 is a ticking time bomb?

I said my 2.7 is a ticking time bomb, because of when it was built.

For me, the issue is fuel injection. Several mechanics have told me that direct injection motors will eventually have carboned valve issues. 2.3 is direct injection. 2.7 has direct and port injection. Port injection keeps the valves clean.

My 10 year old 3.5 Ecoboost DI only motor doesn't have that issue (so while many may have that issue, mine never has and continues to run strong). I don't know what makes mine different from the others, but it might have something to do with driving style.

The 2.3 is only better to me because it’s the one that comes with a manual transmission. There have been and will continue to be failures with both motors and with online forums it seems to be bigger issue than it probably is. It happens unfortunately. Look at the GT350 Voodoo failures. This is across many manufacturers. I come from Subarus and the EJ25 is notorious for failures yet I have been lucky with the 3 I have had.

I originally ordered the 2.7, 2-door, non-sasquatch Big Bend. Due to some still unexplained error, what I received was an Outer Banks with 2.3. (In fact, the entire build is not what I ordered. The colour, trim, options and engine are completely different from my order). Regardless of the colossal screw-up, I took delivery a little more than a week ago.

After driving this Bronco for a short time I can honestly say that not only is the 2.3 adequate, it's actually quite good! Because I received the wrong build I will be driving this one until my new order eventually arrives but now my new order will also have the 2.3.

When Ford releases the 2.3 performance tune you're really going to love it even more. Tunes then the 2.3 into a beast.

I'm curious how many on this thread have driven both? It seemed like a huge difference to me. I have driven a 2.7 4dr, 2dr and a 2.3 4dr.

My 2019 Ranger had the 2.3l engine. It was fantastic. With that said, my Bronco has the 2.7l engine and it is fantastic after 1100 mile in. I figured the difference in MPG was minimal, and I am building a Bronco from scratch. Might as well get the 2.7l.

The 2.3 under the hood is very open and Accessible . The 2.7 under there is almost a nitemare to get to something for a repair. Later down the road the 2.3 might be better for repairs . Huge difference.

That is true about engine bay size / access.

The MIC top is going to hold your build up more than the 2.7l engine. A MIC top with a 2.3l engine would be built after a soft top with the 2.7l. As of right now, a MIC top is the biggest constraint. Get the 2.7l if you want it but don’t switch because you think it’s going to help you get your Bronco sooner if you have a MIC top on order. Just my opinion.

Hurt feelings??

Why would this hurt my feelings when I have a 2.7 on order and can go pay cash for a 392 Rubicon if I wanted too?

I just hate the chest beating Gorilla mentality that if it doesn't have a certain amount of cylinders its worthless.

My Bronco from the factory weighs 4319 pounds per the rail company manifest.

Do you have any easily accessible scales near you? That sounds a little light, but very good if accurate.

Some 3.5's have both. at 10 years old, yours probably doesn't. As you pointed out, driving style has a lot to do with engine longevity. Maybe it would have been better to have said dual, or port injection has the advantage helping valves stay clean.

Right until you realize that most of the heft was probably Sasquatch related, as my 2D 2.7 OBX weighs 4319# from the factory with the heavier V6. You can learn more from reading one rail car receipt than you can from any number of articles by so called automotive experts.

Really. Looks like someone can’t read the scale or the receipt…

A Ford advertising document that expressly informs the reader that the weights it lists are projected vs. a shipping weight with documentation from a scale...

I think I'm gonna have to go with the scale.

So you think that the rail company got it wrong?

I will verify and let you know.

Everyone is an expert until they dislike the facts.

No not at all. I think the shipping weight is based on "base OB" vehicle weight, not actually weight.

My guess (per Ford )is that your OB 2dr 2.7 weighs 4557 at a minimum.

One may dislike opinions but one better understand the "facts". Nothing to dislike about that...

Have my 2.3l/stick Black Diamond and i don't know what people are complaining about with the speed. it goes pretty quickly! it's not supposed to be a sports car it doesn't need to be properly fast. Bear in mind i'm coming from a 1964 Falcon though.
