2.3 ecoboost Thought Experiment

[stmitch]

What's the plan for controlling this thing? An actual ecoboost is direct injected which most affordable aftermarket tuners can't handle. I think you said that MS might be able to control direct injection, but I'm not sure.
Boosting a regular duratec gets you around that. Ranger Duratecs are even more simple than the other Duratecs as they have no balance shafts to add weight and parasitic losses and there's no variable cam timing to deal with either.

So, direct injection and variable cam timing are really nice from an OEM standpoint because they let you fine tune things to get the balance you want between power, fuel economy, and emissions. But OEMs also have armies of power train and controls engineers that can spend literal years tweaking as well as massive budgets. From a swap perspective, it seems like DI just makes things more complex and expensive without adding huge benefit. I think a turbo duratec ("DuraBoost"?) would provide something like 90-95% of the performance of an EcoBoost with less work and complication.

I have few good pics of the L I have handy at home....but this bay pick on the exhaust side will give you an idea.

The L block is essentially the same. 2.0 has a longer rod then the 2.3..... so dwell....rod ratio and valve and injection events are diverse in results. Closed deck vs open deck are variables...but lazy cam phazers will murder head gaskets and heads over 350 HP with either design..

The v6 is a fat bastard. Block variation is high....but. The myth about the bolt patterns are not truly myths...just technically. I have fitted rwd to fwd transmissions...the doweling is different so the blocks being different is valid.

@PetroleumJunkie412 doesn't that look like a Chrysler LA block bolt pattern? Might be worth a measurement or 2 for a NV4500

Not an la. .but with the top mount starter reminds me of a 225.

I would be using the oem control system.

You can't do to the duratech what you get with the ecoboost....the low end torque is ridiculous with the ecoboost.....for daily use and off road wheeling prowess it's the bar....the stuff a 2.0 can do is epic. For max drag racing power and et,s......... building a duratech is ideal...

the eco does have big limits in drive pressure for high rpm Max HP use...but for what my b2 needs. Almost perfection bone stock.

 

[bobbywalter]

So both of my applications between the b2 and the ranger are canyons apart....

From my b2..which the 2.0 is great and the 2.3 eco is perfect... there is my ranger....the new raptor engine can come close to ideal....the regular ecoboost is not so much..

the 7.3 godzIlla I would wager would be better all around and get better mpg.

Of course a Duramax or scorpion would be best.

So bolt in with minimal tuning and maximum reliability power per Dollar.


Godzilla for my specific application. My truck has too much dirty air.. the 3.5 or 3.0 eco boost will be in boost on the highway constantly and I suspect 14 mpg would be tops at 75 mph typically. The 7.3 I would bet will do that or better and is way way dumber.

Clearly the Godzilla underscores the KISS principal.


Big and dumb works for me....just look under my hood the last 12 years.


Will be interesting unravelling one of these in my b2 to be sure....but for the same reasons I like the godzIlla for my ranger, I would prefer a cyclone for the b2.

Alright bobbyD....... Just as a thought experiment.... Jeep pentastar or Dodge 5.7

If free and I need motation

.no issues...I would use a hemi.

 

[alwaysFlOoReD]

I just changed the plugs on the 5.7 in my newest to me work truck, a 2006 ram 1500. All 16 of them....what a pain.... on the drivers side under the brake booster. Flip side I didn't have to buy wires because its coil on dual plugs.

Alright. If you really want a Chrysler product, use this one.

Eww, no.

My few experiences with the Pentastar engines are that they are an over-engineered underpowered Euro-disaster, and so are most of the packages they come in. MCA cars are J-U-N-K.

The 5.7 can throw a rod through the block and as long as it doesn't perforate the cylinder skirt, a new rod, piston, and welding a piece of steel over the hole is all you need to fix it. On the other hand it has 16 spark plugs, because that isn't retarded (And yes, I say the same thing about Ford's dual spark systems).

Ah. Familiar territory.

I ****ing love mopar.

My 6.4 above. Agree.

Dual plug allows for incredible levels of tuning because you now have two different ****ing spark curves. Even without VVT, just having fuel and two levels of ignition control gives you the ability to tune to one exponent above ignition and fuel control.

If you know what you're doing with piston tops and intake runners, you can take an old design and blast it several decades into the future, even decades from now.

Twin spark edis is biggest draw for me to 24v cosworth. It's how they put down stoopid numbers on top of being quad cam.

Tuning trumps displacement with poor management every ****ing time. If you can control it, you can go that much further. One of the German or Italian mfgs just cut loose a 1 or 2l inline3 with a new valve timing concept that produces something like 600-900 ft lb.

@bobbywalter this thing would give you wood.

This is why I respect carbs with appropriate fuel, but efi is superior in every way.

Why would you want to put a DUD engine in a perfectly good vehicle?

You want to use half of (something)?
