Performance & Application
The G25-700 G-Series II is designed as a direct upgrade path for existing Gen I G25 customers, available as a complete turbo unit, supercore, or CHRA-only purchase. Because G-Series II retains Gen I compressor and turbine housings, it fits into the same packaging enthusiasts already trust while delivering increased efficiency at high flow rates. A recalibration is required to fully realize the horsepower gains unlocked by the improved compressor flow. This makes it an ideal choice for builders looking to extract more performance from a proven G25 platform without reworking their turbo system architecture.
