SM350/R - Stock Engine Perfection.

Our 47mm compressor is perfect for the typical street or drift SR20 on pump gas.  The extended-tip 60mm exducer and advanced aerodynamics result in optimal shaft speed and high Turbine efficiency, and all the reponse you could want from a light Rotor and Ball bearing CHRA. Peak compressor efficiency is seen from 12-18 PSI, making it a good match for stock engines or low grade fuels, However camshaft upgrades and Flex fuel / E85 makes for a torquey and responsive combination.

 

SM400/R - All-out Value.

Moving to a 51mm Compressor  Wheel allows for additional pressure ratio and flow rate, and will support a substantial increase in power with a minor (upward) shifting of the powerband. Full boost before 4000RPM and 400bhp is achievable with E85 and supporting modifications. This Turbo is Built around our new and Robust Journal Bearing CHRA, this model offers fantastic value and reliability, while still using the same 47mm Turbine wheel for snappy reponse.

 

SM450/R - Perfectly matched Turbocharger Characteristics.

Our Updated (for 2024) 51mm Compressor and 52mm 9 Blade Turbine allows for additional pressure ratio and flow rate, and will support an additional increase in power output with a solid overall powerband. The Gen 2 Version of this this Turbo still has full boost before 4000RPM but can support 450whp at lower boost due to this updated Turbine and Compressor combo

 

All of our turbochargers are built to order to meet your exact requirements and specifications.  Our current lead time for this turbocharger is 2 to 3 weeks.  Please email info@spectrummotorsportssolutions.com for more information.
