Although I'm still unsure if the turbo piping and what not will be the same from the Elantra GT Turbo and the Elantra Sport, one thing I can guarantee is that the turbo itself will be the same.

For that reason, and surprisingly enough, there is already a turbo upgrade out that essentially utilizes the same oem turbo housing but upgraded internal components of it.

Now again, because it's such a new vehicle, they still haven't figured out what the threshold is and how far they can go with boost on stock internals, BUT you definitely can buy this and keep it in the back pocket, because I'm sure in a month or so, it'll all be figured out ;)

How much WHP does the Elantra 1.6 Turbo produce? Interested to see what kind of boost we're looking at compared to stock and that could be what the GT could gain.

Too risky of a move for me to make especially with what some Hyundai engines are known for. At most i'll do a tune but as these engines prove themselves in the real world i'll consider the bigger mods.

I'm guessing it'll be somewhere in the 165-170whp range taking out drivetrain loss and what not. Which, still to todays standards is a good number considering it's boosted. If I could get it to push the 210whp mark, I'd be a pretty happy camper. May not sound like much, but on the actual street, you'll feel content enough with that.

165-170whp sounds great, but would it affect the Hyundai engine's reliability? Wouldn't want to shorten its lifespan by years if that's a common outcome after an upgrade.

That's what the stock engine should be able to produce from factory (depending on dyno and many more factors) but that's a guesstimate considering "standard" drivetrain loss. So that engine has been stress tested with that given power there. Now the bigger question is after tuning to something above 200whp, reliability is kind of unknown on these things so we're going to have to keep an ear out with the Elantra Sport guys and see what they're dealing with.

So far the Theta engine offered in bigger Hyundai's like the Sonata have problems and there's a massive recall out right now.

As long as I can't find something similar happening to the Elantra and what out GT's will get, tuning to at least 25-50whp more than stock is what i'll do.

That power gain is definitely going to be easily attainable it's just the reliability that'll be out the window along with the warranty haha. Worst case scenario, swap out the motor and throw in a Genesis 2.0T engine, with how long it's been, you could probably get one for a good price.

Well, under 50 horses is doable on most 4 bangers like this without causing harm to the engine, its just warranty you can kiss goodbye.
But we'll have to see what power is like from the factory and how that's distributed throughout the powerband. For all I know modifying the suspension and other areas aside from the engine will be preferred.

Very possible.

Really depends on your preferences and what erks you first haha. A lot of times for me, I'll get in there and the suspension immediately feels too soft for my liking so that needs to be changed. Then I'll typically move on to exhaust because I like to hear my gears as I go through them.

This would be a viable option once the factory warranty or extended warranty ends. By that time, the Elantra GT would be old and blowing something wouldn't break my heart as much. In exchange we'll get more power and torque compared to stock. But that's years later for me.

I'm probably going to cut short and get it done asap. Not too worried about the whole warranty thing. If they want to void the suspension portion of it, I'm totally cool with that. But at the end of the day, they'll have to prove that my modifications caused the issues right?
