SM350/R & SM450/R Bolt-On Turbocharger Systems

Our turbocharger offerings for the R32/R33/R34 Nissan Skyline is something we've been working on and testing in multiple iterations for the better part of 5 years, and we are pleased to finally be able to formally launch this product line. Dyno results and feedback have been very positive, and this was one niche we knew was worth the continued effort. 

While many "high-flowed" options exist on the market today ,utilizing rebuild OEM turbochargers and oversized wheel combinations, our bolt-on Turbochargers for RB20/25 are in a category of their own. 

Instead of relying on the old, problematic journal bearing 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 does require upgrading of the oil and water lines, and we offer this installation kit along with the turbocharger.

Our 3 RB Turbocharger offerings are as follows:

*All options feature dual ceramic ball-bearing cartridges and billet compressor wheels.

SM400/R- Torque and response

Utilizing a wheel combination unique to this turbocharger, the SM400/R is well suited for both stock RB20's wanting more power and reliability than the OE turbo can produce, as well as RB25 applications needing increased response, torque, and power. As with every SM/R turbocharger, this kit is designed to be a full bolt-on to your existing exhaust manifold, downpipe, and compressor connections. A fantastic street and drift combo for your lightly modified skyline, at a very competitive price. Pump-gas output of 350BHP on RB20 and close to 400BHP on RB25 can be expected with supporting mods

SM450/R- More flow, less backpressure, more power.

taking the entry level kit a step further, the SM/R500 kit utilizes a larger 54mm Billet Compressor to increase horsepower capabilities further. While still providing near stock spool characteristics, this setup is better suited to RB25 applications, or RB20 vehicles with upgraded cams and headgasket. Larger, 55mm Exducer Turbine helps reduce Exhaust Manifold Pressure at high boost levels.  Turbine Housing comes standard with Cerakote Ceramic coating. 

SM500/R - Ultimate power delivery.

Beyond the horsepower range of the OEM turbine housing and Internal Wastegate, our SM550/R Turbocharger utilizes a larger, .82 A/R Turbine with Integrated 38mm V-band Tial Wastegate and V-band, 3" stainless Turbine outlet. Standard configuration includes recirculated wastegate dump and 3" inlet compressor housing and a further upgrade to the Billet Compressor Wheel. This Turbocharger represents our "max effort OEM fitment Turbocharger, and helps bridge the gap in power between bolt-on Turbochargers and Top-mount Tubular Manifold / Single Turbo Configurations. 

Please note: OEM turbocharger core charge is applicable for SM/R400 and SM/R500 kits, and utilizes the existing OEM compressor and turbine housing castings, re-machined to fit a new ball bearing CHRA.
