Performance & Application

Part of Garrett’s new GTX40 series, the GTX4088R is engineered for builders looking to step up into larger frame ball bearing turbochargers without sacrificing mounting versatility. The larger entry V-band undivided turbine housing is designed to improve exhaust flow entry while maintaining the flange and clamp compatibility found on Garrett’s new G42 turbos. Its footprint compatibility with competing brand turbos makes it a strong option for builders upgrading from other platforms without needing to redesign existing turbo mounting hardware. This housing configuration suits performance builds seeking a modern, high-flow turbine inlet paired with genuine Garrett GTX-R ball bearing technology.
