Not too big, not too small. ITS JUST RIGHT for YOUR SPEED. Capable of built block power and extremely fast spool times, this turbo can make 500+whp and hit 20psi by 3500-3600rpm. The CorkSport CST5 turbo can be tuned for a more laid-back curve that is stock block safe or pushed to 30+psi for built blocks and auxiliary fueling. No matter what build you have this turbo will be sure to impress.

The CST5 features a MHI Journal Bearing CHRA, 0.82 Turbine A/R and 4” Anti-Surge Compressor Cover

The CST5 turbo will be available in two boost control setups: Internally Wastegated (IWG) & 44mm Externally Wastegated (EWG) w/included EWG elbow pipe & V-band clamp.

Includes a FREE CorkSport 3.5 bar MAP sensor for accurate boost pressure up to 37psi.
