ProCharger 1GN202-SCI HO Tuner Kit for 2004 Pontiac GTO with the original 5.7L LS1 engine. Specify transmission and all modifications; excludes engine swaps.

Included hardware

Standard P-1SC-1 supercharger, dedicated 8-rib drive, GTO-specific air-to-air intercooler, ProFlow valve and charge tubing. Fuel injectors, fuel-system upgrades, programmer and tuning are not supplied. The installer must provide suitable fuel hardware and custom calibration.

Configuration

Choose satin, black or polished supercharger finish. Helical gearing is available. D-1SC is an optional head upgrade. Bracket finish, valve configuration, Race intercooler and balancer choices are specified separately.

Installation requirements

Specify stock or aftermarket balancer and crank-pulley diameter. If using an aftermarket balancer, ProCharger specifies ATI Performance Products 918853 with hardened hub; this is not included in the base kit. Crank pinning is recommended, and a stock-balancer pin kit is supplied. Transmission cooling lines may require modification. The optional Race intercooler requires front-bumper modification.

Build review

Provide model year, VIN, transmission, balancer, fuel system, intended boost and tuner details. Custom calibration is required before operation.

Emissions

ProCharger identifies this configuration as intended for racing or off-road use and not legal for street use in California. Confirm intended use and registration requirements before ordering.

Processing & Shipping Overview

Processing occurs before shipping.

Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.

Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.

For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
