Pro Xe PX400 P1 Volvo S40 C30 V50 C70 Hybrid Turbo Upgrade

PRO XE STAGE 2 HYBRID TURBO

The Pro Xe Stage 2 Hybrid Turbo is the highest-flowing K04-based turbocharger we offer for the Volvo P1 T5 (C30, S40, V50, C70) and P3 S60 T5 platforms.

Built for enthusiasts looking to maximize the potential of the factory K04 footprint, the Stage 2 takes our proven Stage 1 package further by addressing the primary limitation of every K04-based turbocharger: turbine-side flow capacity.

While many hybrid turbo builders focus solely on compressor wheel size, the reality is that the turbine housing becomes the dominant restriction at higher airflow levels. As engine RPM and exhaust volume increase, drive pressure rises dramatically. Eventually, exhaust flow begins to overpower the turbine assembly, reducing efficiency and forcing the wastegate open prematurely. This creates excessive backpressure, elevated exhaust gas temperatures, reduced airflow, and ultimately limits horsepower potential regardless of compressor size.

The Pro Xe Stage 2 was developed specifically to combat these issues.

HOW IS IT UPGRADED? WHAT MAKES IT DIFFERENT THAN STAGE 1?

Every Stage 2 Hybrid Turbo receives an even larger compressor wheel with an advanced 11+0 blade with extended tips, and additional turbine-side modifications focused on improving high-RPM efficiency and reducing drive pressure. Featuring a larger 9 blade turbine wheel that is clipped to allow even more peak flow. Our technicians carefully cut the turbine housing to allow access to maximize volute porting, enhancing top end potential, and reseal it using high quality welds.

Each unit features:

• Fully machined and ported compressor housing
• Fully machined and aggressively ported turbine housing
• Enlarged turbine volute and throat area
• Maximum wastegate and outlet porting
• Lightweight clipped 9-blade cutback turbine wheel
• Upgraded billet compressor wheel package
• Upgraded journal-bearing CHRA components
• Pro Xe 7 PSI Wastegate Actuator
• Pro Xe Plumb Back CBV

The clipped turbine wheel reduces exhaust restriction at higher shaft speeds, allowing the turbine to process more exhaust flow while reducing backpressure. Combined with extensive turbine housing modifications, the Stage 2 maintains efficiency deeper into the RPM range and produces substantially stronger top-end power than traditional K04 hybrids.

Every turbocharger is VSR balanced to 150,000 RPM and tested prior to shipment.

CORE INSPECTION POLICY

Customers wishing to have their existing turbocharger rebuilt or upgraded must contact Pro Xe Automotive before placing an order.

All customer-supplied turbochargers are inspected prior to approval for rebuilding or upgrading. This ensures the housings and core components meet our standards for restoration, reliability, and performance use.

For customers purchasing a hybrid turbocharger and sending their core in after receiving their unit, the same inspection procedure applies. Once we receive the returned core, it will be inspected to confirm it meets our core requirements. If approved, the applicable core refund will be issued.

When you are ready to send your core back, Pro Xe Automotive will provide a return shipping label.
