Official 2.3L Ecoboost Thread

So can this turbo be driven on the street? Dunno, I'm sure people do, but as stated, deep pockets and drive like you stole it, light car, steep gears anything is possible. Maybe I'm getting old, as 80 HP gain on the top 10% of the power range is not worth 50% less torque over 100% of the normal driving range.

Gotta luv this turbo though... if I were in my 20s I guess I'd be thinking about this. LOL

I guess I'm an oldie too, don't need unstreetable turbos and brag-worthy dyno sheets. That's why I love my Jetta TDI, it's a blast starting at 2,000 RPM. I like being able to punch it out of an esse curve and the power be there. The ecoboosts that I've driven have all the power down low but keep pulling through the band. That's why I'm excited about this EB 2.3.

BTW, I keep humming a Neil Young song every time I see your user name.

Another issue about high power and boost, CR drops. The high EB 10.6? CR helps in the responsiveness of the engine. At some point CR has to be dropped for higher boost levels. Cobb changes the piston on their EB, but they don't say what the CR is? 9.5?? dunno on E85..

I'm excited for the 2.3L EcoBoost. Should make for a great tuner-car and track car with such a small motor in a V8 engine bay (for serviceability) and an awesome weight distribution. In stock form it makes >100hp over the popular BRZ/FRS, and >60hp over an S2000.

RWD, >300hp, (assuming) entry-level pricing: should be quite a hit. Not sure about the integrated head-manifold but a turbo swap and 350-450hp would make for an awesome package.

I too am on the fence between getting a 5.0 or the 2.3EB. I've had both. 5.0 in a 2011 Mustang and a 2.3 turbo in an 88 tbird. The tbird ran well and had plenty of torque for a large car. I'd like to be able to tune/mod the EB to about 350 hp. That would make a fun and responsive curve carver.

So no, despite what magazines say you ain't seen a "street driven" 460 HP anything at 2.0 to 2.3 liters. At least by mere mortals. Light car like a hollowed out Civic, no A/C or anything else that might lug the engine, crazy driver, super steep gears like 4.64, and a wad of cash... maybe. So clearly 600 HP EVO are like Unicorns and Rainbows. You see them or dream of them but can't touch one or ride one.

There are tons of daily driven 400hp EVOs out there and 4-500whp+ time attack EVOs.

So... new higher flowing heads, high volume headers / exhaust, pipe it how you want it...

You're only limited by how far you want to go into this engine.

Well, headers and new head probably won't be possible on this engine due to the integrated header system they're using. You could port it, and you could always do cams, but with TiVCT cam swaps are a pain in the ass. I'm guessing we won't see over 350whp on the stock turbo, but I also think that the turbo will be the limiting factor. I think after people swap turbos we'll see the first 400whp cars.

Supposedly this engine is running a GT22, and if that's the case, you may not even see over 315whp. That turbo is rated at 280hp. It's only marginally bigger than the K03 in the 2.0EB. Cobb has seen a 25% power increase on the 2.0 with their tune, fmic, and downpipe and have stated that the turbo is holding them back, especially at the higher rpms. More importantly for some, though, is that people are seeing over 330ftlbs of torque - that's almost stock 5.0 torque.

I think this motor is going to be great for those who autocross or just want to do an intake/tune/catback and be done with it. If people are after HP, they're going to have to sink a ton of cash into this motor and would probably be better off getting a 5.0 to start with.

You're gonna run into feul issues also when trying to make really big power on these cars.

Isn't the 3.5EB kind of tapped out until someone comes up with a better HPFP solution.

According to Autoweek it is going to be built in Valencia Spain.

The Ecoboost 2.0 started out being built exclusively in the Valencia plant. Then in February, FoMoCo split up production of the two liter by moving production of 2.0 EB engines destined for cars to be sold in North America to Cleveland. Valencia now just makes 2.0s for cars to be sold in Europe.

If the Ecoboost 2.3 proves to be a popular option, I can see the same pattern as with the 2.0 developing for the 2.3. At some point it has to be more cost-effective to produce the 2.3s stateside that are destined to be installed in Mustangs to be sold in North American. At what point on the economies-of-scale curve that occurs, I'm not sure. But if you eliminate the step of shipping engines from Spain to Flat Rock and only have to ship them from Cleveland to Flat Rock or from Romeo to Flat Rock, it has to save millions of dollars.

People are seeing 25% gains on the 2.0, so unless the 2.3 and 2.0 use the same fuel systems (which they might) you should be able to see 375+ flywheel hp before running into issues. This assuming the 2.3 is making ~310hp

Yep, as long as you add all the qualifiers I have added, they are "daily driven". deep pockets, light weight, drive it like you stole it, steep gears et all. The only thing I would ask is show me the map to this mythical street 500+ WHP "street drive" turbo, and let's see..

Any turbo made that can support 500+ WHP is so huge the turbo would be in serious surge in the vast majority of driving, sure "street driven" but with no safety, dependability or even pleasure cause the turbo is just far far far far too big to actually use on the "street". Pure bragging rights with no substance.

Here you go - seeing what an eco can do with an aftermarket turbo kit from ATP

It will all hinge on the size of the OEM turbo. My guess is 350 engine with a reasonable safety zone before the choke lines (wheel overspeed). Aftermarket turbo 400 to 460 engine and the limit would be fuel system or the high CR 10.6? I have never run an E85 forced fed car. But am looking forward to it.

If the 6g is the same weight as the 5g, I would assume that the EB would be at least 100 lbs lighter than a 5g V6, add in some weight shift back due to the IRS, we should be looking at:

http://www.motortrend.com/roadtests/coupes/1205_2013_ford_mustang_v_6_premium_first_test/

humm 3400 lbs with say a 52% front 48% rear Add in 350 HP, 31 MPG it really is going to be a Miata, ToyBaru, Hyundai Coupe, old Type R, new Civic SI, killer.

completely agree, I mentioned it earlier and someone stated it's a GT22 which would be a little disappointing. They're only rated at 280hp so unless it's modified for this motor, 350 seems to be on the high end of where it could sit with mods.

Not really. Kids with their true 'daily driven' grocery-getters that they track on the weekends with 400hp with bolt-ons and not huge budgets. Their are endless threads on evolutionm.net

 

[FOURCED]

Exactly. 500-800HP steetable combinations are not uncommon.
