Looking to update your older CTS Version 1 BOSS 500 or 600 kit to latest revision?  These are the parts you need for conversion!

Updated V2 design features our proprietary CTS compressor cover with anti-surge porting, integrated DV/BOV provision and a billet wastegate bracket.  Other parts included are required to change the original BOSS V1 kit to this newest V2 design.

V2 upgrade kit will allow for a neatly installed package; provide better boost control and throttle response, thus making it even easier for your software tuner to maximize your power!

The V1 BOSS kit is not included; this is only an upgrade parts kit.  V1 BOSS kit is required.

Original turbo must be sent in to CTS for V2 parts to be installed.

V2 parts are final sale; warranty will apply but parts are non-returnable for refund or credit.


  • All-new proprietary V2 compressor cover with anti-surge porting and internal DV/BOV provision
  • Compatible with CTS billet aluminum DV or BOV
  • Compatible with factory DV (harness extension required)
  • Updated V2 billet wastegate bracket
  • Updated V2 billet wastegate rod end
