Details

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.

UNRIVALED 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.

PRECISION ENGINEERED

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.

OEM QUALITY

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.

DIRECT BOLT-ON REPLACEMENT

The HPA IS38 Hybrid turbo upgrade has everything you will need for a simple and quick installation including an OEM diverter valve, OEM wastegate actuator, turbo inlet pipe, and silicone hose to adapt to the factory airbox.

First , I want to say "WOW"!
With the Unitronic stage II, the car felt more powerful but kind of "civilized", but with the HPA stage III it is just WILD! Bur controlled wild. The WOT feels like the jet when it gaining speed to take off, and then when I release the gas pedal, it feels like the brake is applied. It is just AWESOME!
Honestly, at very first, I felt kind of "do I really need the bigger turbo?". Now, I am really glad I got it. Thanks, HPA! You guys did a really great job! (Posted on 4/3/2019)

Amazing upgrade. Really blows prior generation turbos out of the water. Going strong for 1 year now no issues. (Posted on 7/31/2018)
Incredibly smooth, endless powerReview by Gerald

I upgraded my GTI to the HPA Hybrid IS38 looking for a flatter power band which runs all the way to the red line. I was previously running HPA's Stage 2 software and while it was very strong I craved having the torque curve flatter and more of it towards the red line. The IS20 is just not designed to do this.

Once the turbo was installed I put it to the test at Area 27 and never felt such a smooth power delivery. Torque delivered is near constant all the way to the red line with very little lag getting back into power coming out of turns.

I couldn't be more pleased with this upgrade and cannot wait to take it to more track days! (Posted on 7/20/2018)
