Turbo Kit for Hyundai Genesis Coupe (2010-2014) 2.0L

Complete intercooled T3/T4 turbo upgrade package for the 2010–2014 Hyundai Genesis Coupe 2.0L turbo four. It replaces the factory turbo and manifold with a cast T3 manifold, a hybrid T3/T4 turbo, 35mm external wastegate, front-mount intercooler, boost controller, blow-off valve, turbo timer and fuel-system parts — a clear step up from the stock turbo setup when you want more airflow headroom. Most installs keep A/C and power steering, and it works with manual or automatic transmissions. Expect about 100 hp over a healthy stock tune at a conservative 8 psi with proper fueling. The 600+ hp figure is the hardware's ceiling at 25+ psi with a built engine, fueling and supporting mods, not a dyno result for a stock car. Engine family reference: G4KF.

Why this kit

• Larger hybrid T3/T4 turbo versus the factory unit, with a .57 trim compressor and .50 / .63 A/R housings
• Cast street manifold with large primaries and a thick T3 flange that carries the turbo's weight
• 35mm external wastegate for better boost control than the stock internal gate alone
• Front-mount aluminum intercooler and full 2.5" piping kit
• Adjustable fuel pressure regulator, billet fuel filter, catch can and electronic turbo timer included

Turbocharger Specs

• Type: T3/T4 hybrid, wet-float bearings, balanced

Exact Fitment — Hyundai Genesis Coupe

• 2010–2014 Genesis Coupe 2.0L turbo (2.0T / 2.0T Premium / 2.0T R-Spec)
• Replaces the factory turbo and manifold as an upgrade package
• Not for the Genesis Coupe 3.8L V6
• Not for sedan Genesis models
• Intercooler piping is universal and needs cutting and fitting; confirm bumper clearance for the front-mount

Not Included

• Chassis-specific downpipe and exhaust beyond the turbo
• Larger injectors, fuel pump and ECU tune (required for meaningful gains over stock)
• Clutch upgrade, boost gauge and wideband
• Oil-pan return bung if your setup needs one

Installation Notes

• Professional installation strongly recommended. Expect cutting and fitting of the universal piping
• The manifold is street cast, not equal-length tubular: stronger and more affordable, with a different spool character than a tubular race piece
• Oil return must drain by gravity; prime the turbo with oil before first start and check for leaks
• Blow-off valve flanges are installed at your discretion
• Keep boost near 8 psi until fuel and tune are upgraded, and let the turbo timer handle cool-down

FAQs

Is this a full turbo kit or just a manifold? It is a full turbo upgrade package: turbo, manifold, wastegate, intercooler, piping, oiling and fuel accessories.

How much power will it make? About 100 hp over a healthy stock 2.0T at 8 psi with a proper tune. 600+ hp is the hardware ceiling with a built engine and full supporting mods.

Can I keep A/C and power steering? Most installs keep both; confirm clearance during mock-up.

Manual or automatic? Fits either when the engine matches.

Is it plug-and-play on the stock ECU? No. Plan on injectors, a fuel pump and a tune to use the extra flow safely.
