While many "high-flowed" options on the market today, utilizing rebuild OEM turbochargers and oversized wheel combinations, our bolt-on turbochargers are a step above this category.

Instead of relying on the old, problematic OEM CHRA, we build our RB turbochargers around the same dual-ceramic ball-bearing cartridge as the rest of our high-performance turbocharger line. This modern CHRA does require upgrading of the oil and water lines, and we offer this installation kit standard along with the turbocharger to ensure simple and straightforward installation.

SM425/R- More flow, More power.

The SM425/R kit utilizes a larger 52mm 9 Blade Turbine wheel for 2024 to increase horsepower capabilities further without added lag. While still providing great spool characteristics, this setup is better suited to high-response RB25 applications up to 18 PSI or RB20 vehicles with upgraded cams and Head Gasket. 

SM505/R - Ultimate Power delivery.

Our SM505/R Turbocharger utilizes a larger Turbine Stage, and can be configured with either internal Wastegate, or integrated 40mm Turbosmart Wastegate and V-band, 3" stainless Turbine Outlet Pipe. This Turbocharger option represents our best all-around OEM fitment Turbocharger combo, and helps bridge the gap in power between bolt-on Turbochargers and Top-mount Tubular Manifold / Single Turbo Configurations. 

SM555/R - Next-Generation Features and Performance

Our Max-effort bolt-on Turbocharger for the RB25 is built around our SR/58HP Turbo. This 58mm compressor will maintain its efficiency up to 30psi of boost and is driven by a 62mm turbine wheel to keep EMAP in check up. 

Both External wastegate options are sold with 3" inlet compressor housings and must be run with an aftermarket 3" coupler and intake pipe.
