GrimmSpeed CHASE JB400 Turbo Subaru 2002-2014 WRX / 2004-2021 STI

GrimmSpeed CHASE JB400 Turbolader Kit für Subaru 2002-2014 WRX / 2004-2021 STI

- inkl. Montagezubehör

Das GrimmSpeed Turbocharger-Programm begann mit der Erkenntnis, dass der Markt einen robusten, schnellspoolenden und leistungsstarken Turbolader benötigt. Die Entwicklung und das Design begann von Grund auf neu und erforderte über 3 Jahre harter Arbeit und Tests. Im Mittelpunkt dieses Projekts stand die Bereitstellung eines OE-Ersatz-Turbo, der in Kombination mit GrimmSpeed-Mods den Enthusiasten ermöglicht, den vollen Nutzen aus dem Turbomotor der EJ-Serie zu ziehen.

Beide unserer neuen Turbolader-Optionen verfügen über hochmoderne proprietäre Kompressoren, Turbinen, CHRA's und Raddesigns, die die Leistung Ihres EJ-Motors zu zwei verschiedenen Preisen maximieren. Das Gesamtdesign durchlief mühsame Gasdurchfluss-Test-Analysen, anstrengende Fehlertests und Motorprüfdynamik-/Straßentests, um den neuen Standard für EJ-Motoren zu schaffen: die GrimmSpeed Chase JB400 und die Overtake BB500 Turbolader!

Das Chase JB400 Turbo ist das kleinere unserer beiden Angebote. Dieses Kit ist ein perfekter Turbo für jeden mit dem Sie das Leistungspotenzial des Autos mit sofortigen Ergebnissen durch Installation/Tuning maximieren können. Der Chase JB400 verfügt über ein robustes 49lb Kompressorrad mit einem 53mm Turbinenrad, um eine schnelle Reaktion und Leistung im mittleren Bereich zu bieten, wo Sie es brauchen. Die Chase Version war in der Lage, 440WHP und 460WTQ auf der GrimmSpeed Stage 3 2020 STI mit dem Zusatz von nur Tuning und Kraftstoff Mods zu schlagen. Das Beeindruckende ist, dass das Fahrzeug in der Lage war, über 400WTQ von 4150RPM zu halten, ein Drehzahlbereich, in dem der Serien-Turbo beginnt an Leistung Im Vergleich zu einem getunten Stamm-Turbo STI, der Chase 400 ist in der Lage, 70 mehr PS und 66 ft/lbs mehr Drehmoment zu produzieren.

Now that you’re familiar with the Chase JB400, it’s time to get to know the big daddy. Introducing The GrimmSpeed Overtake BB500. This turbocharger features world class power delivery and quick spool characteristics. It remains a stock location EJ turbo, but features a larger 55lb compressor wheel and massive 60mm turbine wheel to allow the engine to really breathe at high RPM. Just like with the Chase JB400, drivability was our #1 goal and by combining slick aero wheel designs with a dual ceramic ball bearing center housing rotating assembly, we were able to achieve superior spool results. This allowed us to hit 20PSI BEFORE 4100RPM and out-spool our well-performing Chase turbo by an impressive 150 RPM! When bolted onto our 2020 STI Shop Car, we were able to produce 488WHP and 515WTQ. However, the most impressive part is that the Overtake Turbocharger is able to hold 400WTQ+ from 4000RPM and hold over 400WHP from 4250RPM all the way to Redline! The design philosophy was to keep the turbo in its powerband after shifts and to hold substantially more power than the stock turbo to redline. The Overtake produces 129 horsepower and 109 ft/lbs of torque over a tuned stock STI turbo. This is all accomplished on a vehicle with only simple bolts-on, cars with additional engine work such as cams, intake manifolds, etc will be able to produce even higher gains!



The GrimmSpeed Turbocharger Program started by recognizing a need in the market for a robust, quick-spooling and high-performing turbo. Design began from the ground up and took over 3 years of hard work, testing and development to introduce a product that we're proud to have carry The GrimmSpeed Name. The focus of this project was to offer a stock location OE replacement turbo, which when paired with GrimmSpeed supporting mods, allows enthusiasts to take full advantage of their EJ series turbo engine.

Both of our new turbocharger options feature state of the art proprietary compressors, turbines, CHRA's and wheel designs which maximize the power made on your EJ engine at two different price points. The overall design went through tedious gas flow test analysis, strenuous failure testing and engine pounding dyno/road testing, all to create the new standard for EJ engines: The GrimmSpeed Chase JB400 and Overtake BB500 Turbochargers!

The Chase JB400 Turbo is the smaller of our two offerings, this journal bearing unit is a perfect bolt-on to any stage 3 car, with which you are able to maximize the car’s power potential with instant results through installation/tuning. The Chase JB400 features a robust 49lb compressor wheel, with a 53mm turbine wheel to offer quick response and power in the mid-range where you need it. The Chase Version was able to hit 440WHP and 460WTQ on The GrimmSpeed Stage 3-equipped 2020 STI with the addition of only tuning and fuel mods. The impressive bit is that the vehicle was able to hold over 400WTQ from 4150RPM, an RPM range where the stock turbo begins to lose power. Compared to a tuned stock turbo STI, the Chase 400 is able to produce 70 more horsepower and 66 more ft/lbs of torque.
