SKU: G25-550 Categories: ,


Garrett G25-550 Turbo 48mm 

As the smallest of the G Series Turbos, the G25-550 is a turbo of choice for SR20 and CA18 applications. With the capacity to produce 550 crank horsepower, this turbo offers the opportunity to make more power without sacrificing the responsiveness of a small frame factory turbo such as the T25 or T28.

Generally, we would recommend the G25-550 turbocharger for SR20DET set ups currently running a T25 or T28 who are looking to increase their horsepower up to 400 wheel horsepower. If your goals are beyond 400 wheel horsepower, we would recommend the Garrett G25-660 Turbocharger.*

The Garrett G25 turbochargers are compatible with 1.4L – 3.0L engine displacements and capable of producing up to 550 wheel horsepower. G Series 25 turbochargers are smaller and outflow all comparable products on the market.
