This kit is designed to upgrade the older CTS BOSS V1 500 or 600 kit to the latest BOSS V2 version. It includes the parts required to convert the original system to the updated V2 version.
The updated V2 version uses a dedicated CTS compressor housing with anti-surge ports, an integrated option for connecting a DV/BOV valve and an aluminium wastegate actuator bracket. Other parts required to convert the BOSS V1 kit to the V2 design are also included.
The V2 kit enables a tidy installation, improved boost pressure control and better throttle response, allowing the software tuner to optimise engine operation more easily.
Features
- Brand-new dedicated CTS V2 compressor housing with anti-surge ports and an internal option for connecting a DV/BOV valve
- Compatible with the aluminium CTS DV or BOV valve
- Compatible with the standard DV valve; a wiring harness extension is required
- Updated V2 aluminium wastegate actuator bracket
- Updated V2 aluminium wastegate actuator rod end
- Additional parts required for installation are included
Important
- The CTS BOSS V1 kit is not included; this is an upgrade parts kit only. A BOSS V1 kit is required for use.
- The original turbocharger must be sent to CTS for installation of the V2 parts.
