This combination of products is recommended for those who are not interested in intercooling at this stage and are chasing a full stealth look underneath the bonnet.

  1. Boost upgrade kit
  2. Cold air intake for VS L67 V6 / Cold air intake for VT-VY L67 V6
  3. Cooler thermostat
  4. Bored out throttle body
  5. Comp Camshaft
  6. Crowcams heavy duty valve springs
    LS1 retainers
    Rollmaster double row timing chain*
    machined oil pump cover 
    Viton valve-stem seals 
    Comp valve locks
    Crowcams heavy duty hydraulic lifters
    Crowcams heavy duty pushrods

Power figures will vary depending on a variety of factors including but not limited to; selected camshaft, engine condition, pulley size, transmission and dyno used. A full exhaust system is highly recommended. A custom dyno tune is mandatory following a camshaft upgrade. Please contact us for performance workshops we can recommend around your area who specialize in these motors.

In order to run a double row timing chain, the balance shaft must be disabled by removing the sprocket off the end of the shaft. While complete removal of the balance shaft is possible and would result in the same outcome, it would require the oil gallery to the rear bearing of the balance shaft blocked off. Failing this, virtually zero oil pressure would result on start up.
