ProCharger 1988-1995 GM Truck/SUV 7.4L TBI HO Intercooled System
1GE212-SCI is the ProCharger High Output intercooled system for supported 1988-1995 Chevrolet/GMC 7.4L TBI truck and SUV applications. Select the P-1SC or catalog-listed D-1SC upgrade, gearset and supercharger finish.
Included system components
Includes a horizontal two-core air-to-air intercooler, tubing, ProFlow bypass valve and supercharger hardware using the factory six-rib belt drive. ProCharger lists a ProPump and fuel-management unit (FMU) for this TBI complete system.
Application and ordering details
Confirm the factory accessory and emissions equipment before ordering. Air-pump-equipped applications require a compatible P600B configuration; do not remove required emissions equipment. Supply the VIN, exact model and model year, original 7.4L TBI engine, truck or SUV chassis, 2WD or 4WD, transmission, accessory arrangement and all modifications. Year and engine alone do not establish fitment for every GM chassis.
The base system is listed at 8-9 psi for a stock application. Modified engines and upgraded superchargers require separate fuel and calibration review. Verify emissions eligibility for the exact vehicle and selected configuration before street use.
Special-order planning
A manufacturer order form and nonrefundable deposit are required at time of order. Additional processing time may apply. Confirm configuration, deposit amount and lead time before release.
Configuration photograph
The manufacturer installation image is a reference. Engine layout, equipment and finishes vary by application and selected configuration.
Emissions configuration limits
CARB Executive Order D-365-3 lists the base P-1SC complete-system application for the stated engine and years, subject to its specified configuration and installation requirements. Vehicles certified to ULEV or cleaner emission standards are excluded. The order does not name the D-1SC upgrade; do not assume that upgrade retains the base system exemption. Verify the vehicle emissions label and exact configuration before ordering for street use.
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.
