Fits: Hyundai Elantra N, Kona N, Veloster N and i30 N (2.0T Theta II). The Elantra N and Kona N are a direct bolt-on. The Veloster N and i30 N need our custom hot pipe for a fully bolt-on fit.
What this is
The HT450 is our made-to-order hybrid turbocharger for the Hyundai N 2.0T Theta II platform. We take a brand-new Elantra N turbocharger and build it up: bored out, fitted with a larger, optimized billet compressor wheel, and port-and-polished internal compressor components. The turbine inlet is 5 mm larger, the compressor inlet is 9 mm larger, and it keeps the OEM bearings. Each unit is built to order in Canada.
These turbochargers take the Theta II engine to 400 whp and up. They hold up to 28 psi at 7500 rpm, the mechanical limit of the turbo and about 9 to 10 psi over the OEM turbo. Our own Elantra N 6-speed test car made 490 whp and 464 ft-lb.
We develop the ECU calibration for this turbo in-house and recommend running it. See our Elantra N calibration, Elantra N calibration (2024-2026) and Kona N calibration. You also need a supporting downpipe, such as our catless downpipe (Elantra N and i30 N Sedan) or our 4-inch downpipe with high-flow cat.
Why this turbo
We build power on the car's OEM-style turbo path rather than going to a custom exhaust manifold and a big turbo. The hybrid route needs no engine work: owners make mid-400 whp on OEM sealed blocks, because the N 2.0T is strong from the factory.
The build (billet wheel, port and polish, bored out) gives a broad powerband that holds set boost to redline with no mid-range fall-off, 26 psi all the way to 7000 rpm. It is intended for track use and built to be reliable there: one owner has run this turbo for over 18 months, and owners have run it hard on track for 40,000 miles at 27 psi.

Options
- Vehicle: Kona N, Elantra N or Veloster N. i30 N owners choose the Veloster N option and add the hot pipe.
- Add Custom fit Veloster N Discharge Pipe (Hot Pipe): No or Yes. This is the discharge pipe that makes the HT450 a fully bolt-on fit on the Veloster N and i30 N. Yes is offered with the Veloster N option only.
- Custom build options: powder coating, custom heat shielding and more can be added when you order.
Installation
The HT450 is completely bolt-on, with no fabrication. On the Veloster N and i30 N, the hot pipe makes it a full bolt-on swap. Before install, prepare the car with a downpipe, an intake and water-methanol injection, plus spark plugs; we suggest a high-pressure fuel pump. This is a track and competition part, so follow the rules where you drive.
Because each turbo is built to order, email info@n75motorsports.ca before ordering with your car, transmission and full build so we build the right unit.
FAQ
Will it fit my i30 N?
Yes. Choose the Veloster N option and add the hot pipe.
Can I run this on a DCT car?
No. A DCT cannot handle hybrid power levels with an aggressive tune; TCU tuning and upgraded DCT clutches are still early-stage.
Do I need a tune?
Yes. We develop the ECU calibration for this turbo in-house and recommend running it. See our Elantra N, Elantra N (2024-2026) and Kona N calibrations.
Let customers speak for us
Solid shipping ,good communication ,great product 5stars all the way
First let's preface I have tried three other tuners. Not bad mounting or name dropping as they all were solid tunes. But Daniel just has that magic touch when tuning the 1.6 platform.
The car has a buttery smooth power band making the car feel like a larger displacement six cylinder over a turbo charged car. Plenty of fun to be had at any speed or RPM range.
He will take the time to get you dialed in perfectly for your car. No canned tunes here folks. And if you are a EK1 user three tunes for the price of one simply can't be neat.
I received the Stage 2 tune. Here are my thoughts:
- The shifts are buttery smooth
- I love the auto shift @2000rpm when cruising around town; saves me an extra 2-3mpg overall
- Driving in traffic is a dream now, much better than stock. I don't even hear that annoying shifting fork anymore, lol
- Any and all DCT slips are gone
- The increase in torque limit! This opened up my N75 Stage 3 ECU tune; I can feel the difference. The last time I dynoed, I got 289 lb-ft of torque. But it feels much more substantial than that!
- The clamping force is unreal. I did a run from a dig, and it hooked and slammed through the gears all the way to 7k rpm in each gear. Amazing.
Conclusion: This TCU tune is a must-have. If you have an N75 ECU tune, it is an absolute game-changer! Especially with the Redline MT-LV fluid that I'm running. I can't wait to get my retune with water meth injection. Daniel and the rest of the N75 team are the best!
Works like suppose to be fast delivery after installation 5 minutes drive TPMS sensors lights off everything is normal like from factory 👍👍👍

Product was very easy to install and what a difference in shifting also n75 was super awesome to deal with will shop here again
After using the N75 tune for a couple of months, I can confidently say that it offers the best value for your money on the market. I've tried SXTH and LAP3 tunes before, but since switching to N75, I won't look back. With top-notch customer support, it ensures your car performs better, turning heads at every car meet.
Been running stage 2 off that bat and had some problems here and their regarding fueling. Daniel has been with me the whole way, answering questions and adjusting tunes while adding revisions whenever asked. He answers every question I ask even when they don’t relate to tuning.
Highly highly recommend N75!
Daniel's tuning and customer service makes this product a 10 out of 10. I'm new to tuning and he made the process a breeze. I literally laughed out loud when I first drove the car after installing the stage 2 tune. I still can't believe the difference.
Love the intake, fitment is superb, instal was easy and best of all n75’s customer support is stellar and way above average!
