Many automakers will use an engine that's already in production as a NA engine to make a turbocharged version. My question is, do they do it correctly by using forged engine parts in the turbo version, or do they just slap a turbo on the same engine?
Are turbo engines built more stoutly than NA engines?

Of course popular engines like the EcoBoost were designed to be boosted …
There are lots of good turbo engines from several vehicle brands. This PDF of a VW engine shows many tricks the auto makers use for a turbo engine.

VW EA888 Gen3 engines are very good and reliable.
My 1.8TSI GDI/Turbo has Maximum torque 200 lb-ft @ very low 1,600 RPM and great 43.1 Aver. MPG.
6 years old (in Sept. of this year) and 52,000 miles with absolutely 0 issues.

We loved our 1.8 TSI. However, they are not problem free. Leaky water pumps and worn timing chains are still of concern.
Hyundai did not on my 2010 2L Gen Coupe. Then their programming was so tame people were easily getting another 50-75 hp out of them or even triple that and then engines started blowing. So they upgraded the rods, pistons and timing chain, fixed their programming adding 70 hp or so in their three year model change.
I read about those issues on Vortex. We'll see eventually I guess. How about IVD, is that a big problem on 1.8 TSI?
Shop near me does walnut blasting for $350 so if I start experiencing some engine idle problem or loss of power I'll have it done.
Not enough years or miles to make the good and reliable statement. The Gen2, now older and with more data, wasn't so good and reliable as it aged.
Better than it used to be. I haven't read a lot of reports on needing cleanings.
They are in Hyundai's. First off, connecting rod strength is increased in most all turbo engines. IF Hyundai would use their turbo low pressure hypereutectic pistons ( what I assume use low vs high hypereutectic pistons, because Hyundai defaults to "cheapskate mode" on anything they do) they could of saved 3 of the 4 Billion dollars in warranty repair as half+ of their engine models have piston failures because of piston galling from a soft metallurgy choice on NA engine models.Which in turn takes out bearings and loads up aluminum debris into the lifters and you get the classic "Hyundai Tick of Death"
It's an easy fix, but for 10 years Hyundai/Kia still have the problem, so I feel the top tier executives have an embezzling stake in multi engine rebuilding corps. It is just so cut and dry, why they are having the problem for 10 years and so cut and dry that harder alloys like hypereutectic pistons would fix the issue. Again, I assume Hyundai/Kia used the lesser of strength low pressure hypereutectic pistons, when Audi/VW I assume MAY use high pressure hypereutectic pistons in their turbos because you can "some what" safely get 500hp out of their 2.0 liter turbo stock short blocks.
There are 2020 and 2021 Hyundai 2.0 NA motors dropping like flys with bad/cracked rings/weak in initial design, and too soft of piston alloy in that engine. Of course ALL fixable IF they wanted to. But they have not for 10 years. Buy a turbo Hyundai and you see very few bad engines. We see some or possible proof hypereutectic pistons are used in the 1.6T because they are a hair more brittle. I heard from a Hyundai tech that if you don't drop a piston skirt in the first 1,000 to 5,000 miles in a 1.6T you should have a strong long term engine.

Dang I was looking at the new Santa Fe too I’m leave it alone

I think in some cases the turbo engine can be more robust. Older Subaru turbos for instance. You rarely hear of them loosing head gaskets, where the NA ones do all the time.
To me, what ever is made more robust is cancelled out by the added complexity and added parts under the hood associated with the turbo charging.

Just curious, what are some examples of this in production today?
I think the Santa Fe may have the NEW 2.5 liter dual injected motor. I think we will need 2 years to see if Hyundai went with cheap soft pistons till you can jump on the Hyundai non-turbo bandwagon. I LOVE Hyundai's, but I will slay them if they keep selling garbage. After 10 years of year after year of badly choosing metallurgy for NA engines, we can't assume Hyundai would FIX their on going bad metallurgy choice on their NEW motor. If it is a turbo, I would say buy it, if a non-turbo run away till proof of change.
The Volvo red block turbo engines had different con rods and piston oil squirters which the NA motors lacked.
What I’ve been hearing is the factory turbocharged engines have more robust components where needed. Whether or not that leads to a longer life expectancy compared to a NA engine is up in the air. Overall design probably is a bigger factory.
Regarding Hyundai, they are somewhat of an interesting player. The 2.0T used in the Genesis coupe engine is very weak internally. Compare it to the Mitsubishi counterpart and you will see where Hyundai cheapened out. However, they used a very safe ECU tune to help make it thru the 100k mile warranty.
Hyundai has an interesting position. Hyundai Metal Co LTD is one of the worlds largest metal companies. Cheapening out on metallurgy saves them even more money in the long run. Hyundai’s pride and joy is Hyundai Metal Co LTD, and Hyundai Construction Equipment. Frankly, Hyundai Motor Group (the automobile company) is just a side business for Hyundai to funnel more money to Hyundai Metal Co LTD. The more cars they sell the more money Hyundai Metal Co LTD makes, the more failed engines Hyundai produces, the more money Hyundai Metal Co LTD makes in supplying metal resources. Hyundai as a company is almost like a monopoly, Hyundai Metal Co LTD is Hyundai’s cash cow where all the money is funneled.
In summary, the alarming failure rate of Hyundai engines just makes Hyundai Metal Co LTD more money, which is exactly what they want. There is no incentive to use better metallurgy.
Edit: Hyundai Steel Co LTD is the cash cow. However, there are several Hyundai companies involved in the metal and steel industry.

Interesting take on Hyundai metal. I know Hyundai makes semi trailers, which are made in Mexico. Most other semi trailers are made in the USA.

Ford's supercharged 4.6L in the termi had some serious upgrades over the naturally aspirated version. The FCA Hellcat mill shares architecture but is lower displacement with smaller bores and significantly upgraded internals over the non-boosted HEMI's.
