4G63T Vacuum Pump Details

Everything needed to install a Racing Vacuum Pump in the popular Mitsubishi, Galant, Eclipse, Eagle Talon, Plymouth Laser and most other cars powered by the 4G63T.

Important Note: The replacement crankshaft pulley is not a balancer with a pulley (it replaces the balancer pulley combination) so in order to use this Kit with this pully it requires an internally balanced crankshaft.

The space in the engine compartment is limited at best and requires the removal of the AC compressor and related tensioner and support bracket. The VP102 Sportsman Vacuum Pump bracket bolts directly to the block using the AC support bracket/tensioner threaded holes. The Sportsman vacuum pump attaches to the bracket along with a belt tension adjuster which is part of the bracket system. The Stock Crank Balancer/ two groove serpentine pulley is replaced with the Billet 25% reduction serpentine/ V-belt pulley supplied with the kit (Note that this replacement must only be used with internally balanced race engines as it is not a balancer).

The kit comes with a double baffled breather tank with a clamp on K&N style filter, VCV103 brass vacuum control valve, #10 AN Push Lite fittings including a bolt in bung for the valve cover with #10 Clear Braided hose, V-Belt and all necessary bolts, spacers. The vacuum pump kit was developed to reduce windage and to allow in increase in horsepower by reducing oil contamination of the combustion chambers and to improve ring seal in highly modified 4G63T race engines.

This Kit is for the Mitsubishi 4G63T engine.

• Requires Removal of OEM AC Compressor, support bracket and belt tensioner.
