Overview 

The PSR 7375G DBB Compact Reverse Turbo is a high-performance, reverse-rotation turbocharger engineered for builds targeting up to 1200 horsepower. It features a dual ceramic ball bearing (DBB) center section that ensures ultra-fast spool-up and exceptional reliability under extreme boost conditions. The advanced G-series 73mm billet compressor wheel is paired with a robust 75mm turbine wheel, optimized for both high flow and durability. Housed in a compact design, the turbo utilizes a standard A/R 1.15 turbine housing with a V-band inlet and outlet for easier installation and better sealing under high pressure. The ported shroud anti-surge design improves compressor efficiency and response, while integrated speed sensor and water cooling ports add advanced monitoring and thermal stability. Ideal for tight engine bays and performance-focused applications, this PSR-logoed unit delivers cutting-edge performance with race-proven reliability.
