Hello there! Long time listener, first time caller. I recently purchased the 2018 GT, but my dealership did not have any of the 1.6L Sport models in stock sadly. Since I needed a car then and there, I ended up with the 2.0L and I'm looking to upgrade it with a turbo kit. Can anyone offer a list of parts I'd need for this new model of the car? I have tried to search them out but with the car being so new, I don't know if I'm looking in the wrong places. Any help is appreciated!

As the car is still very new, I think you're going to have a difficult time finding any aftermarket kits at this point. Not sure whereabouts you live, but your best bet might be going to a tune shop, so they can see what exactly is available in their system at this point. That being said I was able to fine one website currently offering some performance mods. Hyundai Elantra - Elantra GT 2018+ - Page 1 - Shark Racing

As Kaeden said, there doesn't seem to be any turbo kits for the Elantra GT yet, but there may be an aftermarket company near you who's willing to develop one so long as they have a donor car (yours).

I was thinking the same thing but not a kit. I had a thought of getting the manifold and turbo from a 2.0t model. Like sonata/Tuscan/etc. any one know of a turbo manifold that shares the same bolt pattern as the gt?

Since someone else has brought this back from the grave I'm in the same boat here.

Didn't have a chance to buy the sport model but would like to add some performance mods(ideally a turbo) to the '18 GT GLS.

I know the 2017+ Hyundai Elantra uses the same 2L NA engine but doesn't seem to have anything available either.

Would be nice if we had a thread or section for people to list where they've found compatible parts.

Adding a turbo means likely also adding a new exhaust, manifold, maybe a clutch(not sure how much this one can handle), plus doing an ECU tune.

Typically adding turbos to non turbo cars you would need a good bit of parts. Since there is a turbo model it is nice as a start to pick up some stuff from that model.

For starters I'd try getting the stock turbo and piping. If it comes with an intercooler grab that and the piping as well. It probably has a diverter valve setup(which is like a blow off valve but reintroduces the air backing the system vs. Venting it out to the atmosphere) which will be needed or you can go aftermarket for an upgrade.
Idk if the turbo from the factory is water cooled or oil cooled. Count on having to cool either with a cooler, possible factory probably after market.
Bigger injectors
A new intake and exhaust set up
Miscellaneous lines (I'd suggest SS braided and nylon sleeved, depends on fluid going through it)
Oil cooler
Bigger radiator
Catch can set up
Tune

Now the list above is not the end all be all. You can add to it but it's just a starter. I added a few things for longevity. If this is a dedicated track car that is different than a quick street car. Hope this helped!

2.0L is an economy engine on an atkinson cycle would likely blow up in 2 seconds with a turbo. The 2.0 Nu engines were never designed for boost you might be getting confused with the 2.0L Theta II engine.

 

[Emos325]

Yes! Ok for some reason I thought the 2.0 was the theta from the I30 just detuned and turboless. Can't remember where I heard or read that but it stuck with me. Yeah no the NU engine is not meant for boost.

Good catch.
