Pro Xe Kia Stinger Genesis 3.3t LAMDA-740 Hybrid Turbo Upgrade

Pro Xe Automotive Kia Stinger / Genesis G70 3.3T Hybrid Turbo Upgrade

Introducing the Pro Xe Automotive Kia Stinger / Genesis G70 3.3T Hybrid Turbo Upgrade — engineered to push the factory Lambda II 3.3TT platform beyond its stock limitations while maintaining fast spool, strong midrange response, and improved top-end power delivery.

Designed for aggressive street and track applications, these hybrid turbos combine oversized billet compressor wheels, upgraded 9-blade turbine wheels, extensive housing porting, and thermal management upgrades to maximize airflow and efficiency from the factory-frame turbochargers.

Unlike many hybrid turbo upgrades, we do not simply replace the rotating assembly and call it finished.

The factory Kia Stinger / Genesis 3.3T turbine housings feature unequal exhaust runner geometry, causing differences in airflow between the two turbochargers. Each housing is individually hand ported and flow tested to bring the airflow characteristics of both sides as close together as possible.

This helps provide more balanced exhaust flow between both banks, improved turbo efficiency, more consistent boost control, and a more predictable calibration throughout the powerband.

Features

Oversized Billet Compressor Wheels
40.2 / 49 / 64T — 6+6 Blade — +3mm

Extended-tip billet compressor design increases airflow capacity over the factory wheel while maintaining quick spool and strong transient response.

Oversized High-Flow Turbine Wheels
38 / 42.1 / 85T — 9 Blade — MGT14X — +2mm

The larger 9-blade turbine design improves exhaust flow and helps reduce turbine-side restriction and drive pressure at elevated power levels.

CNC & Hand-Ported Turbine and Compressor Housings
Each housing is machined and extensively hand finished to improve airflow, reduce turbulence, and properly accommodate the larger rotating assemblies.

Individually Flow-Matched Turbine Housings
Driver- and passenger-side turbine housings are ported independently and flow tested to minimize the factory airflow imbalance between the two banks.

High-Temperature Ceramic-Coated Housings
Helps retain heat within the turbine housing, reduce surrounding engine-bay temperatures, and improve thermal efficiency.

Upgraded Internal Components
Built to withstand increased boost pressure, shaft speed, and thermal load associated with higher-output applications.

Balanced & Quality Checked
Each turbocharger assembly is balanced and inspected before shipment for reliability under high-boost operating conditions.

Performance

Capable of supporting up to approximately  740+bhp with proper fueling, tuning, fuel quality, and supporting modifications.

These hybrids are designed to provide a substantial increase in airflow and power potential without sacrificing the fast spool and drivability expected from a factory-frame twin-turbo setup.

Ideal for:

• Daily-driven performance builds
• Full bolt-on setups
• Upgraded fuel systems
• Ethanol blend applications
• Aggressive street builds
• Drag, roll racing, and track applications

Fitment

Designed for:

• Kia Stinger GT 3.3T
• Genesis G70 3.3T
• Other compatible Lambda II 3.3TT applications using the corresponding factory turbochargers

Kit Includes

• (1) Driver-Side Pro Xe Hybrid Turbocharger
• (1) Passenger-Side Pro Xe Hybrid Turbocharger
• Oversized 40.2 / 49mm 6+6 billet compressor wheels
• Oversized 38 / 42.1mm 9-blade turbine wheels
• CNC-machined compressor housings
• CNC-machined and hand-ported turbine housings
• Individually flow-matched turbine housings
• High-temperature ceramic-coated housings
• Upgraded bearing and sealing components
• Fully balanced and quality-checked rotating assemblies

Professional tuning is required.

Supporting modifications including upgraded fueling, intercooling, intake, exhaust, and proper engine management are strongly recommended when targeting higher power levels.

Actual power output will vary based on fuel type, boost pressure, tuning strategy, engine condition, supporting modifications, and dyno calibration.

Core Process

If you select the Core Required / Send-In Core option, your factory turbocharger will be used as the base for your hybrid build.

After placing your order, ship your complete factory turbocharger to:

Pro Xe Automotive
7478 Buckeye Rd
Liverpool, NY 13088

Please include your name and order number inside the box so we can match the core to your order as soon as it arrives.

Once received, the turbo will be disassembled and inspected to verify that the housings and reusable components are in acceptable condition. The required machining, upgraded internal components, balancing, assembly, and final inspection will then be completed as part of the hybrid build.

Cores must be reasonably complete and rebuildable. Severely damaged, cracked, previously over-machined, or otherwise unusable housings may require replacement parts or additional charges. If we find anything that affects the build, we will contact you before proceeding.

No-Core Option

If you select a No Core Required option, we supply the required factory housings/components and you do not need to send your original turbocharger in.

Refundable Core Option

A refundable core option may be available on select products, but you must email us before ordering to arrange it.

If approved, the replacement hybrid turbocharger is shipped first with a refundable core charge added to the order. Once your original core is returned and inspected, the applicable core deposit is refunded to your original payment method.

Unless otherwise stated on the product page, the returned core must be complete, rebuildable, and match the turbocharger originally purchased.
