Agreed.

They should also rename the 2011+ section to 2011-2014 so this stops happening.

Great Idea. I wonder how soon they will make the change.

This will depend on how well built the 2.3t is from the factory. It is certainly conceivable that big power can be gained from ecu,intake,exhaust upgrades. If the motor is as stout as say the 2.0t motors in say, an Evo, a bigger turbo+intercooler added to the 2.3t can lead to some pretty big power. The good thing about turbo motors is that they are generally designed to take a lot more stress than the average NA motor.

Bang for your buck, I'd take the EB every day of the week. Faster than the V6, lighter and more nimble, good gas mileage, and with an $8k difference from the 5.0, it could have more creature comforts, or be modded out to be as fast as the 5.0.

If you have a lot of money and don't give a f*ck then the 5.0 is the one, but for the sensible, on-a-budget buyer the 2.3 just seems like a steal in my eyes.

Remember the SVO of the mid 80's. It was a turbocharged 2.3 litre with about 200 hp at that time. Ford has already increased that HP by 50% in the last 30 years.

Ford Mustang SVO - Wikipedia, the free encyclopedia
The two 2.3L turbo motors have absolutely nothing in common with one another, other than the displacement, so comparing them is useless. And the EB motors have forged internals, so squeezing more power out of them will not stress the internals any more than it does on a Coyote.

And if you haven't followed, getting more power out of forced induction motors is usually very easy and cheap. No guarantee that will be the case with this particular EB motor, but there's a great chance.

On the GT then, that is 8.57 lbs per hp so if the weight of the GT were shaved to that of the EB, it would only need 411 hp to be equal (roughly speaking). So in theory then, get that EB to 411 hp and go toe to toe with a 2015 GT. Only 101 hp needed. Not sure how that could be done for less than the cost of buying a GT.
There's a $6,000-$7,000 difference between a GT and an EB Mustang.

$6,000-$7,000 will buy a metric poop-ton of power enhancements, and you'd be starting with a lighter car. Lighter is everything.

I'm really excited about the ecoboost stang and cant wait to see the modded numbers once boost is dialed up. I personally don't care if a mustang is a 4, 6 or 8 banger. As long as it gets good horsepower and fuel economy I'm down. Hell, I would love a boosted diesel 6 stang!

And for all the people who say if you bought a mustang you shouldn't worry about fuel economy aren't being practical. My pony is my daily commuter (I'm sure many here are as well) so I need to think about fuel economy and it needs to be reasonable. That's why I love my 6, I have 300whp and 30+mpg. I get my cake and eat it too. Now if I can have 350 or 400 whp and 35+mpg then I would just be ecstatic... that's why I'm excited about the ecoboost. So yes, horsepower in my mind is just as important as fuel economy...the more the better!

Plus, its very easy to get power for cheap in a turbo. Just tuning alone usually nets you around 50+hp. I had to add every single bolt on mod on my 6 to get that!

The ultimate deciding factor is can the motor handle the increased boost and how much. My friend had a tuned mazdaspeed 3 that made 300whp and his motor pretty much died at around 150k km.

Having a sleeper EB4 that hangs with a 5.0 would be pretty cool.

I think the EB4 has a ton of potential but the sky is the limit for the 5.0.

If money is no object than load up a 5.0 (mine comes in at over 42k the way I want it configured). If money is a factor than you have to choose what is more important, creature comforts or raw horse power. Its a lot easier to add power.

Its been under discussion behind the scenes since the S550 debuted on GMA back in December.

It will happen soon enough.....

I personally do not trust the reliability of a turbo 4 over a n/a v8. For these reasons I will get v8. I also don't really think a muscle car should sound like a civic.

My signature consists of a simple fact. Mustang is a muscle car. Have a nice day.

I'd take the 5.0 all day every day over the Ecoboost if it was no cost considerations. I'm still interested to see how the Ecoboost performs and it's reliability.

Real simple

Gas mileage and crappy sounding exhaust the 4 cylinder.
Roar and sound of V8 muscle the 5.0.

All kidding aside the Eco boost should provide very impressive power along with torque and gas mileage. But I have reservations on the 4 cylinder especially when guys turn up the heat. Longevity comes to mind, just saying. whereas you already know what you can expect from the 5.0. Just saying.

Heard that a LOT back when the 4cyl imports started making an imprint in the car culture back in the '70s. None of the theory came to any fruition.

I was in Baldwin, Mo a week or so ago and a Taurus SHO, evidently modded at least with exhaust, took off from a light and it sounded like the worst fart I've ever heard! Like Sheet is an understatement!

Probably went like hell but ??

I'm a bit excited about the EB 2015, but will be keeping my 2011 5.0 and will replace my 2012 Focus with a 2017 EB Mustang. Only worry is I'll probably do it and then find the 2.3L Turbo getting 21mpg avg. but at least I won't be daily driving a Focus anymore.

I own a 2012 5.0 and it is indeed a fast car. I also owned a 1987 Buick Grand National. With a chip change and a variable fuel regulator, that car went from 13.90s to high and mid 12's easy. Boost is a wonderful thing. The 231 cubic inch Buick V6 at 14.6 pounds boost is putting in the same amount of fuel and air as a 462 inch motor. don't count the 2.3 out. I also swapped the entire drive train from an 87 Grand National into a 1984 Monte Carlo SS. With bigger turbo, injectors and tuning with a laptop the car went 11.01 at 122. The Coyote engine is still amazing to me though, and I still can't believe the power it puts down. Way more than any 60's muscle car I drove back then, including hemis and 454 Chevelles!
