HPA K04 Hybrid Turbo Upgrade - Longitudinal

With a market flooded with poor quality aftermarket clones and modified OEM assemblies, HPA has taken a fresh approach to supplying its customers with a K04 Hybrid for the Gen 1 and 2 EA 888 and EA 113 engines at an affordable price. 

Designed To Perform: 

The HPA K04 Hybrid Turbo is one of the most advanced units available in North America and has been designed for a seamless installation, without the need for custom fabrications or aftermarket diverter valves. A newly cast compressor housing allows the factory K03 diverter valve to be installed in the OEM location, without a CNC port adapter. The compressor wheel has been  re-designed and the custom blade profile and billet construction allow for quicker spool  and higher output across the full rpm range.

OEM Quality: 

Each CHRA is built to met or exceed OEM quality specifications, with the individual components of the rotating group balanced on a Schenk Balancer. Once fully assembled, each complete CHRA assembly is balanced with a VSR Balancer. The VSR Balancer is used and approved by leading turbo manufacturers Borg Warner, Garrett Honeywell, and IHI, ensuring a perfect assembly.

All Inclusive Hardware Kit: 

This kit is a direct replacement of your stock K03 in most cases and includes everything you require for your upgrade, including a turbo muffler delete for smoother exhaust gas flow, OEM diveverter valve, and OEM N75 Boost control solenoid which guarantees compatibility with all aftermarket tuning.

Features: 

•  Make up to 355HP / 347TQ (Fuel quality, supporting mods and tuning dependent.)
• Direct Replacement (in most cases)
• Compact Design for Faster Boost Response and Turbo Longevity
• Turbo Muffler Delete for Smoother Exhaust Gas Flow
