Just had this unit installed on my Alltrack as part of a Stage III build from my local VW dealer (who is also the APR dealer). I chose HPA over a straight OEM R version for the advanced engineering and quality HPA has invested in it. Loving it so far, and looking forward to putting over 100K miles on it!
HPA is proud to offer an OEM+ IS38 Turbo that addresses all the reliability concerns plaguing the OE IHI IS38. This is a perfect service part for blown IS38 turbos, or a great upgrade for GTI owners looking to upgrade their IS20.
We have a considerable number of upgrades made to the VAG OEM IS38 to address all reliability concerns and believe our product will be one of the most reliable options out there.
The HPA OEM+ IS38 Turbo features a fully upgraded and redesigned bearing system. This bearing system has been proven out in the field with 100% reliability on our 450 HP level Hybrid Turbos. We are providing the exact same package in an OEM+ design. This is insurance from the known weaknesses of the OEM IHI turbo.
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 with better spool and anti-surge characteristics while still being compatible with all brands of IS38 tuning
We found on some OEM turbos after long-term heat cycling from high EGTs to cold, the wastegate itself physically bends. Some of them have snapped and ended up in the catalytic convertor. This is a concern especially for customers who attend track days and drive their cars hard. We have upgraded all our wastegates with a highly heat resistant Inconel version to ensure this never happens.
BOLT ON FITMENT
The HPA IS38 Hybrid turbo upgrade has everything you will need for a simple and quick installation including an HPA Turbo Muffler Delete, OEM diverter valve, OEM wastegate actuator, turbo inlet pipe, and silicone hose to adapt to the factory airbox, and OEM installation kit along with all hardware required. All turbos will ship from HPA with the wastegate actuator set to the exact voltage needed for true plug-and-play installation.
HPA OEM+ IS38 equipped GTI Delivers on the Ultimate Endurance Test!
Jamie Orr, Max Everhard, and Pedro Ruta Jr. set out to go from the top of South America to “fin del mundo” in Argentina in the Rallywagen, a slammed 400HP Volkswagen MK7 GTI. This GTI traversed nine countries, eleven border crossings, eight thousand five-hundred miles! They tackled the Andes Mountains, Bolivia salt flats, Brazil, Bubble Gun Treffen, local police, glaciers, the Strait of Magellan, and more.... All the way to the most southern paved road on our planet.
"I probably can't put into words how much I absolutely beat on the turbo from the moment it was installed.. It was flawless, with 12,000+ miles on one oil change... We went Coast to Coast in the USA non-stop in sub-30 hours as the first drive with it basically. In South America there were days that we would literally drive at 50-75% throttle until the fuel tank was empty, stop to refuel without turning the engine off, and then do the same, over and over again. On one specific day I drove with questionable fuel from 500 ft to 15,500 ft, continuously going full throttle to pass tractor trailers, then stopping for photos, and repeating."
