Fits:

• 2017 - 2021 Honda Civic Type R (Hatch FK8)

Includes all gaskets and hardware needed for turbo replacement. Remapping is recommended to fully realize the turbo's potential — note that the peak dyno figures below were measured with HKS's Mastery ECU PHASE3, which is JDM-only and not available in North America; a comparable aftermarket tune here will get you most of the way there. Intercooler kit sold separately for safe high-power use.

_______

The GT4845 is a direct-fit replacement using the same layout as the factory turbo, so there's no fabrication or modification needed to install it, and no fuel system upgrade required thanks to its sizing. What it delivers over the stock turbo is meaningful high-RPM output that the factory unit simply can't reach — boost holds at high RPM instead of tapering off the way the stock turbo does.

HKS tested this at Fuji Speedway and saw a genuine 12 km/h top speed gain (232 to 244 km/h) and 3 seconds off lap time — real track validation, not just a dyno number. With the JDM-only Mastery ECU PHASE3, peak output reaches 384ps and 492N·m, up from 330ps and 478N·m stock, while primary exhaust pressure stays the same as stock for a smooth power delivery that doesn't strain the engine.
