Hyundai Veloster NStage 1 to Stage 4 tuning guide

The Veloster N shares its 2.0 turbo with the i30 N, and one of its best upgrades is the Elantra N's bigger turbo, which bolts on with a new hot pipe. It was sold in Korea and North America, never in Europe. Most tuners quote wheel horsepower, and the limits are the high-pressure fuel pump, the injectors, heat and, on DCT cars, the clutch packs.

Years: 2019–2022 (US)
Engine: 2.0 T-GDi turbo four
Gearbox: 6-speed manual; 8-speed wet DCT from 2021
Stock power (US): 250 hp / 275 hp, 260 lb-ft

Power by stage

Stock is Hyundai's engine figure: 250 hp, or 275 hp with the Performance Package (standard from 2021). Stage 1 to 4 are the tuners' own figures at the wheels (whp); N75 measures a stock car at about 225–240 whp. The top of Stage 3 and 4 needs methanol or ethanol.

1

Software, with colder plugs

265–275 whp

N75's Stage 1 calibration takes the Veloster N from about 225–240 whp to 265–275 whp, depending on whether it flashes your own engine computer or a spare one. Plug-in modules and the JB4 piggyback are the no-flash alternatives. LAP3 also tunes the Veloster N, but its product page shows a power table headed "Elantra N", so we don't quote it.

Typical cost: calibration CAD 699.99–899.99 on your computer or CAD 1,499.99–1,999.99 on a spare (N75); JB4 $599–$799; plug-in modules $485.10–$697 (aFe, RaceChip) or €799 (DTE).List prices, Sept 2026, before shipping, import tax and fitting.

Recommended with Stage 1

Colder spark plugs required HKS M45XLNGK (heat range 9)
LAP3 requires HKS M45XL plugs and N75 specifies heat range 9.
High-pressure fuel pump recommended LF 2.0T pump (genuine Mobis, via LAP3)N75 upgraded pump
N75 calls the pump "a weak point" and recommends replacing it before tuning.

Before you buyAsk whether the recall update is on the car: Hyundai's recall 262 covers the pump's engine-computer software (the recall notice), and a later bulletin extends the pump's warranty to 15 years or 150,000 miles (the bulletin). US 91 octane is about 95 RON and 93 about 98 RON.

2

Downpipe, intake and cooling

280–300 whp

Stage 2 adds an intake, a downpipe and a bigger intercooler with N75's Stage 2 or Stage 3 file. N75 claims 280 whp with an intake and 295 whp with an intake, fuel pump, intercooler and downpipe; on a spare computer its Stage 3 claims 300 whp with water-methanol injection.

Typical cost: downpipe $787.50 with a 100-cell catalyst (XForce) or CAD 760 catless (N75); intake $418.95 (aFe); turbo inlet $156.45–$245.61 (aFe, Forge); intercooler $799 (Wagner) or £613.48 (Airtec); fuel pump $385 (LF, via LAP3).List prices, Sept 2026, before shipping, import tax and fitting.

Parts list

Downpipe required XForce 4" downpipe with 100-cell catalyst N75 catless downpipe
N75 says its downpipe "Adds 25+WHP on a ECU tune"; XForce's keeps a high-flow catalyst.
Intake and turbo inlet required aFe Takeda intake aFe turbo inlet Forge turbo inlet SXTH turbo inlet
aFe claims +15 hp for its intake; Forge claims +10 hp with its inlet.
Intercooler recommended Wagner intercooler (2019–20)Wagner intercooler (2021 DCT)Airtec intercooler
Wagner's has about twice the stock volume; Forge measured 48°C air into the engine with the stock cooler after heat soak.
Charge pipes optional aFe BladeRunner charge pipes (automatic only)
Aluminium pipes for higher boost.
Fuel for the top of Stage 2 LF 2.0T fuel pump LF 2.0T injectors
N75 reports a "large amount of failures" of the stock injectors and requires new ones for its spare-computer Stage 2.
Cat-back exhaust optional XForce Varex cat-back aFe Takeda cat-back (2021–22)Milltek
Mostly sound; aFe claims +10 hp.

Before you buyCatless downpipes won't pass inspection; keep a catalyst and the original parts. Water-methanol and ethanol aren't sold at Israeli filling stations.

3

Elantra N turbo or a hybrid

350–400 whp

The Veloster N's favourite upgrade is the Elantra N's larger factory turbo. N75 claims "399WHP and 400WTQ" with its swap kit, and LAP3's package with the same turbo claims 300–380 whp. N75 also makes a stuffed stock turbo, the HT350, for 350 whp and more.

Typical cost: Elantra N turbo swap $1,500 (LAP3) or CAD 2,399.99 (N75); N75 HT350 CAD 2,499.99; SSP DCT clutch kit $1,599.List prices, Sept 2026, before shipping, import tax and fitting.

Turbo upgrades compared

Kit	Fuel	Claimed power	Claimed torque	Notes
N75 Elantra N turbo swap	—	399 whp	400 wtq	Hot pipe fix included; more than 350 whp at 23 psi
LAP3 400BHP N turbo package	—	300–380 whp	—	Elantra N turbo and a custom charge pipe
N75 HT350	—	350 whp and more	—	Your stock turbo upgraded, or a new one
LAP3 Pure550N hybrid	—	"support over 550BHP+"	—	A hardware rating; needs an Elantra or Kona N turbo core and a custom hot pipe

Parts list

Bigger turbo required N75 Elantra N turbo swap LAP3 N turbo package N75 HT350
Each needs a tune written for the new turbo.
DCT clutch kit DCT cars SSP 8-speed DCT clutch kit
SSP rates its kits at 500, 600 or 700 lb-ft; N75 says the DCT "cannot handle hybrid power levels".
Water-methanol injection for the top figures LAP3 water-methanol kit
LAP3 recommends it with its higher-boost files.

Before you buyHyundai says the DCT's gearbox software has to match its hardware revision (the bulletin), so ask the shop to check it before any gearbox tuning. LAP3 calls the head-bolt threads "a weak point for aluminum blocks".

4

Big hybrid or turbo kit, and a built engine

450–490 whp

N75's HT450 hybrid claims 450 whp at the red line and says it is "capable of 490WHP" at 28 psi. Beyond that, LAP3 sells a full turbo kit with its own manifold, and KDM Tuners a forged engine kit it says will "support up to 700+ hp", which is a hardware rating, not a car figure.

Parts list

Big hybrid or turbo kit required N75 HT450 (Veloster N version)LAP3 turbo upgrade kit
LAP3's kit needs its Pro-Tuner file and methanol.
Forged internals for the biggest builds KDM Tuners 2.0T engine build kit
Forged pistons, H-beam rods, bearings and studs; KDM says a sleeved block and fuel work are needed above 600 hp.
Head studs and gasket required ARP CA625+ head studs Cometic MLX head gasket
Clamping the head at high boost.

Before you buyThese figures need ethanol or methanol, which aren't sold at Israeli filling stations. Choose one shop to build, tune and stand behind the whole car.

Questions to ask the shop

Will you flash my own engine computer or a spare, and does your file include Hyundai's fuel-pump recall software?
What does the file make on 95 and on 98 RON, measured on a Veloster N rather than an Elantra N?
On a DCT car, what torque will you run, and will you check the gearbox software matches its hardware revision?
Do you want a new high-pressure fuel pump and injectors before Stage 1 or Stage 2?
Is my car a 2019–20 or a 2021–22, and which intercooler, boost pipe and turbo inlet does that call for?
Will the car still pass the annual inspection, with a catalyst and no fault codes, and can it go back to stock?
