Introduction: Unlocking the True Potential of Your Genesis G70
The Genesis G70 is already a standout in the sport-sedan segment, blending refined luxury with a chassis that begs to be pushed harder. For the enthusiast who wants to go beyond factory output, upgrading the turbocharger is one of the most effective modifications you can make. Whether you drive the 2.0-liter turbo four or the twin-turbo 3.3-liter V6, a properly selected turbo upgrade can deliver substantial horsepower and torque gains while improving overall driving response.
In this guide, we break down five of the most trusted turbo upgrade brands for the G70: BorgWarner, Garrett, Precision Turbo, ATP Turbo, and Vivid Racing. Each brand brings distinct engineering philosophies, price points, and performance characteristics. We’ll cover key features, real-world gains, installation considerations, and what to expect when you pair these turbos with supporting modifications and professional tuning.
Before diving in, remember that a turbo upgrade is a major modification. It requires careful planning, quality fuel system upgrades, a robust intercooler, and a custom ECU calibration to safely unlock the extra power. Always work with a reputable tuner who has experience with your specific engine platform.
BorgWarner: Precision Engineering for Serious Power
BorgWarner has long been a benchmark in forced induction, supplying original-equipment turbos for many production vehicles and dominating in motorsport. For the G70, their EFR (Engineered For Racing) series is the go-to choice for owners who want a blend of quick spool, high efficiency, and bulletproof reliability.
EFR Turbo Family
The EFR lineup includes a range of compressor and turbine sizes to suit different power goals. For the G70 3.3T, popular options include the EFR 7163 and EFR 7670. These turbos feature a Gamma-Ti turbine wheel that reduces inertia for faster spool, a stainless steel turbine housing with integrated wastegate, and a supercore design that minimizes internal friction.
- Performance: The EFR series delivers excellent transient response, often achieving boost as low as 2,500–3,000 rpm on the 3.3-liter engine. On a well-tuned setup with supporting mods, you can expect 80–120+ wheel horsepower gains over stock.
- Durability: The use of ceramic ball bearings and a dual piston ring sealing system provides extreme longevity even under sustained track use. Many owners report tens of thousands of miles without issue.
- Installation: BorgWarner offers plug-and-play kits for the G70 that include all necessary piping, wastegate, and hardware. However, the turbo must be clocked correctly, and oil/coolant lines may need modifications depending on the kit.
Considerations
BorgWarner turbos generally require upgraded fueling and a custom tune. On the 3.3T, this often means high-pressure fuel pump internals or a port-injection system. The EFR 7163 is a strong match for daily-driven cars wanting quick response, while the 7670 better suits those chasing 600+ horsepower.

Garrett Motion: Proven Performance, Global Support
Garrett is a name that needs little introduction in the turbo world. Their aftermarket G-Series turbos have become the gold standard for hundreds of platforms, including the Genesis G70. Garrett’s focus on advanced aerodynamics and core durability makes them a top choice for both street and competition use.
G-Series for the G70
Garrett’s G-Series line includes the G25-550, G30-660, and G35-900 (dual-ball-bearing variants). For the G70 2.0T, the G25-550 is an excellent upgrade, capable of supporting 450+ wheel horsepower with quick spool. For the 3.3T, many tuners prefer a pair of G25-550s or the larger G30-660s in a twin-turbo configuration.
- Quick Spool: Garrett’s billet compressor wheels and aerodynamics reduce lag significantly. On the G70 3.3T, a twin G25 setup can spool as fast as stock, sometimes even faster, while providing 100–150 whp increase.
- Wide Range: Garrett offers dozens of A/R and trim options, allowing you to tailor the boost curve to your driving style—whether you want early torque or high-rpm top-end power.
- Proven Track Record: Garrett turbos are used in IMSA, WRC, and countless street builds. Their global parts distribution ensures you can easily service or rebuild your turbo if needed.
Supporting Mods
Like BorgWarner, Garrett upgrades demand proper fuel supply. On 3.3T cars, you’ll likely need a port injection system or upgraded LP/HVP fuel pumps. A front-mount intercooler with increased core volume is also mandatory to keep intake temperatures in check.

Precision Turbo: High-Flow Specialists
Precision Turbo & Engine has carved a reputation among racers and serious street builds for turbos that flow massive amounts of air. Their PTE and Gen 2 series are widely used in high-horsepower Genesis applications. If your goal is to exceed 700 wheel horsepower on the G70 3.3T, Precision Turbo should be your first stop.
Popular Models for the G70
The 6266 Gen 2 and 6466 Gen 2 are two common choices. The 6266 is a journal-bearing turbo that provides excellent flow for 500–650 whp, while the 6466 (also journal bearing) can support 700–800+ whp with proper tuning. Precision also offers ball-bearing versions for faster spool.
- High Flow Rates: Precision’s compressor maps are tuned for maximum airflow without sacrificing efficiency. The 6466 can move over 70 lb/min of air, enough for 800 hp on the 3.3T.
- Customization: Precision offers multiple turbine housing sizes and AR options, as well as custom rebuilds. They also sell wastegate actuators with different spring pressures to match your boost target.
- Customer Support: Precision’s phone and email support is known to be helpful, especially when dialing in a new setup. Many tuners prefer them because of the availability of technical data.
Things to Keep in Mind
These turbos are larger and heavier than stock, requiring a custom downpipe and intercooler piping. The 6466 may also need a stiffer wastegate actuator to prevent boost creep. Expect to upgrade the fuel system significantly—often with direct injection fueling, port injection, or both. On the 2.0T, a single 5858 Gen 2 is a great match for 500-600 whp.

ATP Turbo: Balanced Upgrades for Daily-Driving Excellence
ATP Turbo takes a slightly different approach: they focus on bolt-on upgrade solutions that maintain OE-like driveability while boosting power. For G70 owners who want a noticeable bump in performance without the complexity of a full custom build, ATP offers whole turbo kits that retain the factory twin-turbo layout on the 3.3T.
Bolt-On Kits
ATP offers upgraded turbochargers specifically designed for the G70 3.3T (and 2.0T) that directly replace the factory units. These kits include new turbo cores, wastegate assemblies, and all necessary gaskets. They typically use larger compressor and turbine wheels inside the original factory-style housing geometry to simplify installation.
- Balanced Performance: ATP kits are tuned to deliver 40–70 whp gains with no custom tuning required when used with their supplied flash tune (available through select dealers). For owners who want a full custom tune, the potential jumps to 80–110 whp.
- Quality Engineering: ATP uses 304 stainless steel housings and high-temperature coatings to prevent heat soak. Their wastegates are sourced from Tial, ensuring accurate boost control.
- Affordable Options: Compared to a full custom twin-turbo kit, ATP’s offerings are competitively priced. Many owners can install them over a weekend with basic mechanical skills.
Best For
These turbos are ideal for the daily driver who wants a “stage 2” level of power without tearing the engine bay apart. They work well with an upgraded intercooler, intake, and exhaust. However, for truly high horsepower (over 550 whp), you’ll need to move to a larger frame-size turbo like those from BorgWarner or Precision.
