Overview
Turn your Hyundai Genesis Coupe 2.0T into something that actually justifies the “turbo” badge. The Tomioka Racing TD06-20G Turbo Upgrade (TR-TG1001) is the largest direct bolt-on turbo available for the factory 2.0T manifold and downpipe flange.
Built around a TD06-20G wheel set with genuine MHI journal bearing internals, this turbo is designed to support up to 500 HP with the right fuel system and tuning, while still retaining reasonable spool for a street-driven Genesis.
If you’ve outgrown the stock turbo and you’re tired of it falling on its face up top, this is the logical step before going to a full custom/rotated setup.
Why upgrade from the stock Genesis 2.0T turbo?
The factory Genesis Coupe 2.0T turbo is small. It’s fine for mild bolt-ons, but:
-
It runs out of airflow quickly at higher RPM
-
It heats the charge air and approaches overspeed if you push it harder
-
Power flattens out instead of pulling through the top of the rev range
The TD06-20G upgrade fixes that by giving you:
-
Much more compressor and turbine flow (52.5/68 mm compressor, 61/54 mm turbine)
-
Headroom for serious power gains (up to ~500 HP with supporting mods and tune)
-
A turbo that still bolts to the OEM manifold, downpipe flange and oil/water connections
Bottom line: you get real top-end power and room to grow without fabricating an entirely new turbo system.
Key features & benefits
-
Largest stock-location bolt-on turbo for Genesis 2.0T
TD06-20G wheel set in a housing that uses the Hyundai Genesis standard flange, so it drops onto the factory manifold location.
-
Supports up to 500 HP
Turbo is rated for up to 500 HP with proper fuelling, intercooling and ECU calibration – more than enough for a hard street car or track build.
-
Genuine MHI journal bearing center section
Uses high-quality MHI journal bearings and components for durability and reliability under high boost, backed by a 1-year warranty.
-
Billet wastegate actuator, 0.8 bar base pressure
Comes with a billet internal wastegate actuator set at 0.8 bar / 11.76 psi base pressure to hold stable boost and maintain control at higher power levels.
-
Complete bolt-on kit contents
Includes the turbocharger, actuator, oil & water lines, and gaskets/hardware kit so you’re not chasing fittings and crush washers during install.
-
Street & track capable
Ideal for fast street cars, HPDE, time attack and drag where you want big top-end power without giving up the bolt-on convenience.
Vehicle fitment
Designed for the first-generation Hyundai Genesis Coupe 2.0T:
Some catalogs also list 2009–2014 coverage. If you’re on an early car or a non-US model, verify your turbo flange and oil/water line style before ordering.
Turbo characteristics
From Tomioka Racing’s own data: Tomioka Racing (TR)
-
Bearing type: Journal
-
Flange type: Hyundai Genesis standard
-
Compressor wheel:
-
Inducer: 52.5 mm
-
Exducer: 68 mm
-
Turbine wheel:
-
Inducer: 61 mm
-
Exducer: 54 mm
-
Turbine housing: 8 cm²
-
Wastegate actuator: 0.8 bar / 11.76 psi base pressure
-
Maximum rated power: 500 HP
These dimensions put the turbo firmly in “serious build” territory – big enough to move real air, but not so large that the car becomes a lag monster.
What’s included
Kit contents as supplied by Tomioka Racing: Tomioka Racing (TR)+1
-
1 x TD06-20G turbocharger assembly
-
1 x Billet internal wastegate actuator
-
Oil & water pipes/lines
-
Gaskets & hardware kit (gaskets, studs/bolts, etc.)
Everything is designed for the stock-location bolt-on install on a Genesis Coupe 2.0T.
Required supporting mods & tuning (read this)
This turbo will happily support power the stock fuel system and tune cannot support. Plan on at least:
-
ECU tune (mandatory – do not run this turbo hard on a stock tune)
-
High-flow downpipe and exhaust
-
Upgraded intercooler (front-mount or high-efficiency core)
-
Intake system sized for the airflow / MAF or MAP scaling
-
Fuel pump and injectors sized for your power and fuel (pump gas vs E85/mix)
-
Boost control solution (good 3-port EBCS if you’re going past actuator pressure)
For higher power, expect to also need:
-
Stronger clutch or upgraded automatic transmission tuning/components
-
Better cooling (radiator, oil cooler) if you track the car
If someone wants 500 HP without budget for supporting parts and tuning, this is the wrong part for them.
Installation notes
-
Direct bolt-on to OEM manifold and downpipe flange for the Genesis Coupe 2.0T. Tomioka Racing (TR)+1
-
Professional installation is strongly recommended – this is not a “driveway in an hour” job.
-
Always pre-lube and prime the turbo (crank with fuel/ignition disabled) before first start.
-
Double-check oil feed, oil return and coolant connections for leaks before road-testing.
-
Get the car tuned immediately after installation and avoid full boost pulls until the tune is finalized.
This turbo is sold for off-road / competition use where emissions rules allow — make that clear in your store policies to match TR’s waiver. Tomioka Racing (TR)
Positioning vs other options
Use this in your sales copy / Q&A if needed:
-
If the customer wants stock-like power with a little bump, they don’t need this.
-
If they want a dependable 350–450+ WHP street/track car and are willing to do fuel, exhaust, intercooler and tuning properly, this TD06-20G is in the right window.
-
If they want 600+ HP, they should stop pretending they’re doing a “bolt-on” build and move to a bigger custom or rotated setup.
