Performance & Application

This compressor housing is purpose-built for the Garrett GT4202 platform, including GT4202R and GT42RS turbochargers, on both ball bearing and journal bearing configurations. The large frame, high-flowing design combined with the cast-in ported shroud helps extend the compressor’s operating range and resist surge at the top end of the map. It’s an ideal fit for builds pushing high boost and airflow demands where a V-band compressor outlet is preferred over a traditional hose connection for a tighter, more secure seal.

Compatibility & Fitment

• Garrett GT4202 (ball bearing version)
• Garrett GT4202 (journal bearing version)
• Garrett GT4202R
• Garrett GT42RS
