G-Series II is Garrett's second-generation update — new compressor aero delivers up to 10% higher flow than Gen I at peak pressure ratio and peak turbo RPM, with increased efficiency at high flow rates.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis part number supersedes the G25-550. For anyone already running a Gen I G25, it's a direct upgrade path with just a CHRA purchase — G-Series II uses Gen I compressor and turbine housings, so nothing else on the car changes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e 48mm compressor inducer, 60mm exducer, 65 trim, 0.70 A\/R.

On a 2.0L this spools like a much smaller turbo and still supports serious power — the right pick for a road course or autocross car where the area under the curve matters more than the peak.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eCalibration is required\u003c\/strong\u003e to take advantage of the increased flow.
