CorkSport | CST5 Turbo Upgrade (IWG) - Mazdaspeed 2006-2013

CorkSport - CST5 Turbo Upgrade - 2006-2013 DISI MZR Mazdaspeed

Balanced Performance

The CorkSport CST5 Mazdspeed Turbo is designed with the ideal balance in response and power for the daily-driven Mazdaspeed. Just between the CST4 and CST6, the CST5 can reach ~20psi by 3500-3600rpm and carry power to 7300-7500rpm.

Stock Flange Fitment

Ease of installation and use is key to all CorkSport Performance Turbochargers. The CST5 retains the factory-style turbine flanges for a painless installation. The turbine housing is designed with a 0.82 A/R to balance response and top-end power.

Anti-Surge Compressor

4” anti-surge ported compressor housing is utilized for peak performance operation. The anti-surge porting increase the compressor map width paired with an industry standard 4” inlet to maximize the use of 3.5” and 4” intake systems.

High Performance CHRA

MHI Journal bearing CHRA housings are used for both the CST4 and CST5 turbochargers for their increased cooling capacity and proven reliability. High-performance journal bearings and a 360-degree high-performance thrust bearing is used. Comparing the compressor and turbine wheels, we have a wheel size ratio of 1:15

Billet Compressor

Utilizing the Gen1 GTX71 billet compressor wheel, the CST5 can efficiently support 56 lbs/min flowrate and boost pressures over 30psi.

High Flow Turbine

Paired with the compressor wheel is an MHI TF06 high-flow turbine wheel. This wheel uses a 9-blade design which reduces overall rotating mass and thus improves response and spool.

Tunable Wastegate Actuator

The Internal Wastegate Actuator uses a larger diaphragm and piston for improved boost control for the larger CST5. Also included is an assortment of springs so you can specifically setup your CST5 for your Mazdaspeed.

All Hardware Included

The CST5 comes will all the necessary hardware for installation saves you time and money on gaskets, studs, and the specialty parts.

Boost Control

Internal Wastegate setup includes the 0.82 A/R IWG turbine housing and tunable IWG Actuator.
