Is there any improvement on these in the past 4 decades? The Fords are still blowing head gaskets is my understanding and as far as the high RPM ceramic bearings and cooling system connection to lower oil temperatures- Nope, didn't work 40 years ago.

Any attempt to increase boost and your problems have just started. Now the intercooler is a great addition, plenty of underhood room as engine is a 4 cylinder still. All the extras to make it into something it will never be (dual exhaust lmao, at least tail of car looks balanced). Something's going to give, hope the past mistakes there aren't getting repeated. Loved to hear the whine though, almost as good as an opened up 4V.

Best of luck to those that have gone that route but when I hear turbocharged, I cringe. Strange that nobody ever hears about the trouble connection with this technology, whitewashed......

If you are referring to the Focus RS head gaskets, that was because the wrong gaskets were being installed at the plant building the engines. The 2 different version gaskets look very similar.

The ecoboost engines don’t seem to have higher failure rates than other NA engines. There have been some turbo failures but there have also been a bunch of duratec V6 engines with failed water pumps that leak into the oil and take out the engine. The 5.0 has also had some issues.

These engines were designed to be turbocharged from the get go and most are 2nd generation with lots of improvements. It’s not difficult to build a reliable turbocharged engine if you start with that in mind. Look at turbo diesels - they’ve been around for decades and are known for longevity.

Thanks on the updates, things may have advanced then? Of coarse they were used on aircraft way before and never knew of any problems either. Diesels also and can get upwards of 200 or 300K miles, this is true.


Could of been AiResearch turbochargers period and putting them out there not really tested. Not a Ford this was an '84 Dodge Daytona. Had small V8 power with 4 cylinder parts. Forged rods even, yea right. After I put one through the side of the block lol. Motor change, junkyards had oodles of parts and the complete cars too.

I just think things up to put on forum, glad to get a few answers:)

The biggest difference is that these new engines are designed for turbocharging from day one as opposed to simply taking a NA engine, beefing it up and bolting on a turbo.  A 2.0L Ecoboost engine and a 2.0L Naturally aspirated engine are very different.    The turbo technology itself is also much improved.  

 

Also the turbos are smaller so they spool up quickly with almost no turbo lag, so driveability isn't an issue.   The problems you're seeing are the normal engineering issues you see any time you introduce something new.  The 2nd gen ecoboosts fixed a lot of those issues including head cooling.   They're also moving to both port and direct injection to solve other issues.

 

You should go test drive a 2.3LEB mustang and see for yourself.

I'd say so-do keep in mind that you didn't have the CPU power you have today to control fuel curves, etc like you did in the 1980s either.

 

Just as an example-a tune in a SHO (Twin turbo V6) can drop a stock 1/4 time of 13.7 down to a high 12 second car without blowing the engine or transmission up-is pretty good indication that cars have come a long way from the 1980s. I've had a tune on my car since 7-8K and I have about 72K on it now without any issues.

Speaking of the 2.0 EB, are any of the I4 EB's going to be getting dual injection?

Yes sir! I was amazed at how good this powertrain is. All of the previous 4-cylinder Ecoboost cars I've driven from Ford and Jaguar Land Rover had a lot of lag and lousy fuel economy. The automatic and manual transmissions didn't go well with the engines either.

 

Then I drove the 2018 10-speed auto Mustang Ecoboost. Lag is minor, engine felt responsive, and the trip computer showed 32 mpg on the mostly highway test drive. Engine sound could be better. But overall, 2.3L Ecoboost + 10 speed auto works great in Mustang. I'm convinced that it should be fine in other vehicles too. That's why I'm planning to buy a 2019 Ranger next year with the same engine and transmission.

The lag is not the engine, it's the Electronic Throttle Control which can be eliminated with aftermarket parts or a tune.
