Hi everyone, first post here, just picked up a Gray Sport w/ a manual transmission. Loving the car so far. I've owned 14 cars, mostly Japanese with manual transmissions, this is my first Hyundai. I really like it, almost feel bad that Hyundai has to sell these for under $20K. I looked at all of the C-segment manual transmission cars under $20K and nothing comes even remotely close, penalty boxes all of them. I've had many Hondas, but that new Civic, ooof, Honda beat it half to death with the ugly stick, put hub caps on it, and wants to sell it for $18K?

Anyway...about that engine.

I'm a big time car nerd and like reading up on the cars I've owned/own. There is a lot of info out there for many engines, search google for your engine code and find all kinds of stuff. The last few cars I've owned, I've been able to find a lot of information on the engines (FB20, 2GR-FE, J30A4, etc.)

There isn't much out there on these engines.

What is the engine code? Are the internals different than the naturally aspirated 1.6L? According to the internet, Velosters have been known to blow up, has Hyundai changed anything over the years? What kind of turbo / who makes it?

Any info would be appreciated!

Idk about engine codes like hondas use, but there is tons of info on the 1.6 T-GDI.

I don't think a lot of velosters are blowing up? Lol this engine is kinda becoming one of the fleet engines for Hyundai and Kia (popping up all over, like the VW 2.0T in VW/Audi)

We are learning this engine is (minorly, it seems) different than the veloster engine. Follow Tori motorsports thread about it. Most people are suspecting a bigger turbo on the Elantra vs the veloster.

There isn't a lot of in depth info because this car has only been out for a couple months, Tork is just releasing parts weekly now so it seems more in depth info will be available in the near future once shops start ripping them apart. (Size/kind of turbo, internals different than the veloster, etc etc)

Thanks, I don't know if there has been "a lot" of Velosters blowing up, but just surfing around, I found pictures of actual holes in engine blocks, like literally blew up. Most likely due to some bad tune, but still.

Just kinda curious if these engines respond well to tunes in terms of having overbuilt internals, or if they're already at or near the limit hardware-wise.

We have quite a bit of information regarding the 1.6T, now as others have said we have not pulled the engine or torn it completely down yet, so the inside is still somewhat of a mystery, however, I am going to go out on a limb and guess that the 2016 VT share the same engine, which has essentially been fixed from the factory for all of the issues that were found from 2013-2015.

As for Veloster's blowing up, the tune had very little to do with it, in fact the 2013-mid 2014 all came from the factory with very weak pistons. We found this out the hard way, and did extensive testing on those pistons to verify that that was the issue, since then hyundai has changed their piston design, in 2014 they moved over to a "B" piston, which was significantly improved over the previous "A" Pistons. We actually were the ones that sorted out the issues, and developed the first forged rods and pistons for the 1.6T. To this day, unless an engine swap, or different internals were put inside of a 2013 we will not tune them over 230whp. So yes, there have been quite a few issues with the veloster, though lucky for the Elantra guys, the known issues have been rectified before the 1.6T was put in the Elantra. If there are any further issues, we will find them, and we will correct them.

I would be more concerned with the head studs, last we seen Hyundai had not done a revision to them, they are incredibly weak and causing head gasket failures left and right. Which is why we developed a head stud and layered head gasket to maintain strength under higher power applications. Only time will tell if Hyundai put better quality studs in the engines.

Thanks for the info, that's interesting stuff.

About the head studs, I'm assuming you're saying they're weak when subject to additional boost from a tune? Or even weak with a stock tune?

I guess if they're weak with a stock tune, I'll look at the bright side, at least Hyundai will fix the headgasket up to 100K miles, and while they're in there, they can clean the carbon off the valves!

Yeah, those head studs stretch and cause gasket failure, as Tyson noted. I'm pretty sure that's what was wrong with my VT when I traded it in for the ES, and I think it's what caused the motor to let go 2 years prior. Certainly increased boost will make head stud stretching more likely. However, the ES peaks out around 12psi where the '14 VTs peaked at 18.5 and the 15s and 16s peaked around 16psi. The 15s and 16s were pretty safe to tune, so that should mean that you can add a whole lot more boost to an ES without too much worry. If you do the upgraded head studs and gasket then you'll be extremely safe.

Seems like every vehicle has it's achilles heel. The Camry V6 I had previously, known as one of the most reliable cars you can buy, has water pump issues, VVTi cam gear issues, and automatic transmission issues.

Hopefully Hyundai has made revisions to address the weak points, obviously it's in their best interesting considering their warranty.

Pretty amazing that Hyundai will warranty a high strung engine for 10 years / 100K miles.

These issue stink, but at least you have the warranty, and with a head gasket repair, at the very least, you get a clean head and valves. Maybe if you're lucky, you'll get a whole new engine, and while they're in there, they can put in a fresh clutch!!

Geez, now I almost want the engine to blow, at like 60K miles or so. Fresh engine, clean valves, new clutch, that'd be a nice 60K service courtesy of the dealer (obviously I'd pick up the clutch). :)

They did replace my short block under warranty when it popped, but I put it back to stock aside from the exhaust before I brought it in to them. The doofuses couldn't figure out that the ECU was tuned. If you have a bunch of aftermarket parts on the car then you're going to fight a hard battle to get it covered under warranty, Magnusson/Moss Act be damned.

And, to be fair, the '15 and '16 VTs didn't really blow motors unless they were pushed incredibly hard. So, at this point, the platform is relatively stable. They're just things to beware of when pushing the envelope.

Even with all those problems it sounds like your dealer experience was still good overall which is what some people can only dream for. Not all dealers do well at handling issues.

It was - after I put my foot down with them. They tried to claim that my downpipe caused an overboost condition and thusly caused the head gasket and #1 cylinder to fail. I argued that that was obviously nonsense, but they held their ground. I sat on it for a day and called them back and told them that I wanted the warranty refusal, including reasoning, in writing. They called back the next day and said they'd cover it - they knew they had a legal battle on their hands that they were going to lose, so they covered it.

It pays to know what you're talking about and be able to handle these louts at the dealerships. If you're professional, confidant, and subtly let them know that you're on top of it then maybe, just maybe, you'll have a not terrible experience. Heh.

I still feel that I got lucky.

I agree. All the Hydundai dealers around where I live are A-holes. Especially the service department.

I have a quick question. Ive had my ET for just under a week now and am reaching the end of my 600 mile break in that the booklet talks about that I looked over briefly during a lunch break. To be fair, my car history is not so extravagant. 98 Civic, 10 Corolla, 14 Sentra, and now my ES. None of the prior cars had any real fun power to play with.

So for my quick question, where is the turbo at? I haven't been able to find it so Im assuming its either pretty small, or Im looking in all the wrong places 😅

Back of the engine. Just follow the air intake tube from the airbox to the back.
