The Garrett CHRA G-Series II G40-1250 is engineered for performance enthusiasts who already run the G-Series Gen I platform and want a genuine upgrade path without replacing their existing housings. Built around Garrett’s latest compressor aero technology, this core assembly delivers a meaningful step forward in flow and efficiency for builders chasing more power from their current turbo setup. It’s the ideal choice for owners looking to maximize their investment through a CHRA-only upgrade rather than a full turbo replacement.
