Please check out our installation pricing regarding our stage kits and other LSJ items.
* Special Notes:
  • This kit requires that the customer clearance the end of the snout so that the smaller supercharger pulley will fit. (We offer machined snouts.)
  • This kit is now completely plug and play allowing you to easily return it to stock if need be.
  • You’ll need a special tool to remove your stock supercharger pulley, and install the new modular hub.
  • You’ll want to invest in some sort of scan gauge to monitor KR and have a better understanding of everything when you run this much boost.
  • If you get belt squeak check the belt routing around the AC Compressor for an improper alignment.
  • We recommend the use of the stock air box setup as aftermarket intakes are notorious for improper MAF sensor placement and result in skewed air/fuel ratios and can cause lean conditions.
