HPA HPA IS38 Hybrid Turbo Upgrade
The HPA IS38 Hybrid Turbo features a custom compressor and turbine wheel design capable of holding up to 450HP* with a flat torque curve from 3800 RPM to redline! Our turbo is a natural upgrade to IS38, IS20, and even IS12 equipped cars where the OEM units lose breath mid-way in the RPM range. Coupled with a major redesign of the OEM bearing housing, the HPA IS38 Hybrid turbo is the perfect upgrade for those looking for a significant performance boost with improved long-term reliability.
The IHI IS series turbos have been known to restrict oil flow under sporty driving conditions which can cause premature failure of the bearings resulting in broken turbine shafts. This can lead to catastrophic engine failures due to oil and debris being pushed out into the exhaust system and igniting. The HPA IS38 Hybrid is an insurance against these types of failures.
HPA has spent 4 years of research and development to completely rethink the bearing housing design. Each turbo requires precision CNC machining of the intake and exhaust housings and include an HPA proprietary mixed-flow turbine wheel, and CNC machined billet compressor wheel. All components are completely upgraded to ensure lubrication for both reliability and peace-of-mind.
Each CHRA is built to meet or exceed the 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 ensuring a perfect assembly.
