New turbocharged engines built to last?

My 1976 refrigerator is still running great. Reviews on new ones say they’re junk in comparison.

They are DI. But so is the Ford 5.0 V8 this year. They actually have both port and direct injection this year, I believe. And autostop tech. And a 10 speed trans.

GM 1/2 tons are DI as well, at least the 5.3 is.

They’re doing some complex stuff to eek out another 1 or 2 mpg’s.

The Tundra’s still rockin a 350. Or at least a 5.7 :grin:

Haha, very true. Too bad it’s “harvest gold” paint isn’t en vogue.

Lucky guess!!!

Don’t buy a new car; keep that Scion ramming forever. Lots of new cars have direct injection. My 4-cyl 2017 Accord does, and just about every car I looked at in 2017 does. Direct injection gives a boost in power, turbo or supercharging does, as does variable valve timing. Well, VVT keeps you near the sweet spot wrt power longer and I’m considering that an increase in power. Honda’s smallest engine in the Accord is a 1.5L turbocharged and direct injected engine. They decrease engine size from 2.4L to 1.5L and improved average fuel economy from 30 mpg to 33 mpg.

That’s either a compliment or a snide remark. I’ll assume it’s a compliment.

Direct injection without the port injection supplement also causes extreme carbon buildup.
Supercharging, turbocharging, and VVT do not cause problems. Don’t mash everything together in how they work, what they do, and what their side effects (if any) are. It’s bad science.

It’s the port inject when used alone that I think is a mistake. I believe that’s why Ford has added port injection and why Toyota/Subie used both in combination in their sports car.

Can’t keep stock holders happy if they last 50+ years now can we?

Is is possible that you actually meant to say “It’s the direct injection when used alone that is a mistake.” . . . ?

:confused:

Yup, my bad. Nice catch.
Is is true.

From what I have seen so far, turbocharged engines built in the past 10 years should be more durable than those built previously. However, If you want a car that makes the “cars people keep for 15+ years” list, better choose a naturally aspirated car.

I bought a 2013 2-door BMW specifically because that was the last N/A car they built.

My 1949 Frigidaire is still running like new. Defrosting is a pain though.

I think BMW still makes plenty of N/A cars, even 2 doors.

Pretty sure they don’t.

I guess I spoke tooo soon. My apologies. :frowning:
I’ll sit down and shut up for a while.

Don’t do that, do research instead. You might turn out to be right :grin:
All who post as friends are always welcome.

It is supposed to be running forever. Apple spell check screwed me again. Sorry for not spellchecking spellcheck as I normally do.

The list of power enhancers was only that. I was not suggesting that any of them are necessarily going to reduce reliability. We had a discussion about direct injection a while back. I found a reference on line that said early implementations with low temperature injection ports were more likely to retain a smut. This is the part of the port inside the combustion chamber. Eventually, this smut would obscure the injectors and lead to poor running engines. GM and others late to introduce DI raised the temperature and that allowed the fuel to completely oxidize, leaving no smut.
