Description

BRAND NEW Levego Performance - Project X (Upgrade)
1853-970-0000 Stage 1 Cartridge

“Bigger Flow. Sharper Response. Hybrid Power.”
Unlock hidden power without replacing your entire turbo. This billet compressor wheel upgrade is precision-machined from high-strength aluminum for maximum durability and airflow. Designed as a direct fit to your existing turbocharger, it delivers:
- Increased airflow capacity for higher boosts and more horsepower
- Improved efficiency with advanced blade aero design, reducing turbo lag
- Stronger construction to handle higher RPM and extreme heat
- Cost-effective upgrade without the expense of a full turbo replacement

Perfect for enthusiasts who want extra performance while keeping factory fitment. Requires professional installation with housing machined and proper balancing for reliability.
A compressor wheel upgrade- only upgrade means you keep the stock turbine housing, bearing system, and center section, but replacing a compressor wheel with a larger, more efficient, or stronger one- made from billet aluminum.
*** Note: Compressor wheel is enlarged, so the compressor housing needs to be enlarged too to fit in.

Key benefit:
-Stronger & More Durable – Forged billet material resists cracking and fatigue under extreme boost pressures
- Precision Engineering – 5-axis CNC machining delivers perfect blade geometry for maximum efficiency.
- Better Airflow – Enhanced blade design increases air intake, improving horsepower and torque output
- Faster Spool & Response – Lightweight construction helps your turbo build boost quicker, reducing lag.

Fits the following:

DETAILED ANALYSIS

Original Wheel (OEM)

Nose Diameter 10.89 mm — the larger hub nose restricts airflow into the inducer region, which limits response and efficiency at higher compressor speeds.
Standard geometry and blade height tuned for factory boost levels, ensuring stability but not optimized for maximum flow.
Weight 24.19 g — indicates cast construction and thicker hub sections.

Project Fun

Nose Diameter reduced to 9.13 mm, improving entry flow efficiency.
Keeps OEM exducer size (46 mm) for direct fitment — no machining required.
The smaller nose and lighter billet design enhance spool and transient response while maintaining stock compatibility.

Project X (Stage 1)

Nose Diameter 8.99 mm — the smallest among all three. This tighter and more aerodynamic nose profile reduces obstruction in the hub area, allowing smoother and faster air entry into the compressor blades.
The smaller nose also improves blade inlet efficiency, complementing the larger inducer (39.55 mm) and wider exducer (55.61 mm) to achieve a significant airflow increase.
Although heavier overall 28.74 g — due to the larger diameter and blade mass), when considering the size increase relative to the weight gain, it can still be regarded as a weight-reduction wheel. The refined nose geometry offsets inertia losses, maintaining strong spool response despite the higher flow capacity.

IMPORTANT

Please use the above information to determine if the part(s) in this listing fits your vehicle. Do not fully rely on the eBay ‘compatibility’ feature.

The most reliable way to make sure of the compatibility of the model of turbocharger is finding the part number from the nameplate of your old turbocharger.

DETAILED BENEFITS

Power Gains
Horsepower and Torque: Upgrading to a larger or more efficient turbo can significantly increase both horsepower and torque. Many TD42 enthusiasts report gains of 20-50% in power, depending on the specific turbo used and supporting modifications.

Fuel Efficiency
Optimized Air-Fuel Ratio: A better turbo can improve the air-fuel mixture, leading to more complete combustion. This can enhance fuel efficiency, particularly during highway cruising or when under load.

Throttle Response
Reduced Turbo Lag: We have redesigned our turbo to have a much better match with the TD42 engine.
This results in a much faster turbo spool and reduces any turbo lag, compared to the OE turbocharger. In other words, our turbo will provide quicker acceleration and a more responsive driving experience.

Towing and Load Handling
Increased Torque: The added torque from a turbo upgrade is particularly beneficial for towing and hauling heavy loads. It helps maintain speed on inclines and improves overall drivability underload.

Performance at Altitude
Compensating for Thin Air: At high altitudes, thinner air can lead to power loss in naturally aspirated engines. A turbo can help compensate for this by forcing more air into the engine.

Tunning Flexibility
Custom Tunes: Upgraded turbos often come with options for custom tuning. This allows for adjustments to fuel maps and timing to maximize performance and ensure reliability.

Direct bolt on
We offer various types of turbine outlet patterns:T3-Vband/ T3-3 bolt/ T3-V band. Most customers can find easy access to the installation.
