These Additional Items are Standard Equipment on All Type I, II & III GEX Hi-Performance engines, 1776 cc & Higher.
Case
We use only the later model cases with the larger oil passages and the dual pressure relief valve system. After align-boring and installing case savers, the case is machined out for the Cima Mahle pistons and cylinders. Using a Bridgeport Mill, we cut 3 steps inside the cylinder holes to match the cylinders perfectly. The use of 3 precise cuts instead of 1 large cut, leaves more material on the case for increased strength and durability.
Big Valve Dual Port Heads
Don't be satisfied with the stock heads you'll find on our competition's engines. Step up to GEX Big Valve Heads. Increasing the size of the intake valves results in additional horsepower gains not possible from stock heads. So, we machine and install the larger 39 mm intake seats and valves.
Double Thrust Cam Bearings
This is the ultimate in a camshaft bearing. Normal VW cam bearings have the thrust shoulder on only half of the thrust bearing. The double thrust bearings we use, provide an equal 360 degree surface to support the camshaft and reduce wear.
Camshaft
Our GEX 110 cam is set up for .431 inches lift and 284 degree duration. This cam has a mild idle and is superior for street and off road, providing excellent low and mid range power.
Heavy Duty Oil Pump
These pumps, with the 30 mm gears increase oil pressure and lower engine operating temperature. The result is increased engine life.
8 dowel Crankshaft & Flywheel
With the increased horsepower created, you have to be able to transfer it to the wheels reliably. The weakest link in the chain is the stock VW 4 dowel crank and flywheel connection. All GEX Hi-performance engines come with this 8 dowel setup (SPG pattern) to effectively double the strength in this area and prevent crankshaft / flywheel separation.
Heavy Duty Swivel Adjusters
These superstrong rocker arm adjusters are designed to spread the impact load on the valve ends and improve control of valve setting tolerances. They will not bind or distort the end of the valve stem.
Hi Carbon Steel Pushrods
These pushrods insure constant valve control under all conditions. They are heat treated to resist flexing and bending at high rpm's.
Cima Mahle Piston & Cylinder Set
The name speaks for itself. When only the finest pistons and cylinders available will do, this is the logical choice. Preferred by more top competitors than any other brand, we agree. Cima Mahle's quality is unsurpassed.
Bolt on Valve Covers
Stops Valve Cover oil leaks and adds that custom finishing touch to any air cooled 1200 to 1600 cc based engine.
