Garrett G25-550 Turbocharger 48mm (Reverse Rotation)

Description

Garrett G25-550 Reverse Rotation Turbocharger 48mm 

As the smallest frame available from the G Series Reverse Rotation range, this compact unit is one of 7 reverse rotation turbochargers available from Garrett. Whether for a symmetrical twin turbo application or for a single turbo performance application, this turbo offers all the best features of the G-Series, including improved air flow for ultimate efficiency and horsepower!

TIP: Garrett horsepower ratings are calculated at crank horsepower not wheel horsepower. As an estimate, reduce ratings by 20% for wheel horsepower ratings. For the G25-550, we would recommend it’s use in up to 440 wheel horsepower applications.

Generally, we would recommend the G25-550 turbocharger for SR20DET (and other 4 cylinder engines) looking to upgrade/increase their horsepower up to 400 wheel horsepower. If you have a 4-cylinder engine with goals are beyond 400 wheel horsepower, the next option to look at is the G25-660.
