*** This is a “universal” Tuner Kit designed for vehicles equipped with a carbureted small block Chevrolet engine. System requires the installer to supply a carburetor enclosure or carburetor hat (see options below), a high volume fuel pump and properly jetted carburetor unit (with mechanical secondaries). Horsepower gain of 30-75%+ depending on boost levels and engine volumetric efficiency. Installation time is estimated at 4-10 hours depending on application.
***System designed to work on engines equipped with a “long” water pump and OEM v-belt drives or serpentine accessory drives (OEM TPI/TBI applications, 1990-1995 and GM Performance Parts accessory drive system #’s 12497697, 12497698 and 12497869). For correct belt alignment, the proper accessory drive crank pulley and accessory bracketry must be used, and are not included or supplied in this kit. Engines equipped with a “short” water pump will require a long water pump to be installed.
***This system can be used on engines with and without power steering. Most OEM serpentine Saginaw type power steering pumps can be attached to the Vortech mounting bracket using the supplied hardware in the kit. For engines equipped with v-belt power steering and accessory drives, a Saginaw style pump will be required as well as an optional Vortech power steering pulley assembly (part #4GP110-051). This assembly includes all required hardware, tensioner assembly and anodized billet aluminum pulley. Depending on the vehicle, power steering lines may require fabrication.
