Case
 Only
late style dual pressure relief cases are used. They are first
hot tank, then thoroughly washed by hand. The cylinder base
area is decked and surfaced on a Bridgeport Mill to set
initial deck height alignment between all four cylinders and and
to eliminate oil leads at the base of the cylinders. Case inserts
or "Case Savers" are installed, Align Boring and all
remaining machine work is done and then the case is thoroughly
cleaned again and painted.
 "BIG
VALVE" 041 Style Heads
JCS
buys thousands of head cores every year. A good portion of those
are scrapped for the aluminum "scrap value" because
they are too worn to be rebuilt or require too much work. We select
only the best cores for rebuilding to insure a high quality, dependable
finished product and to minimize the amount of labor put into
rebuilding a head. These select cores are then fully machined...
valve guides are replaced with manganese-bronze guides designed
for extreme wear resistance and improved lubrication. All
valve seats are replaced with heat treated chromoly tool
steel seats that promote a quick, high heat transfer
rate from the valve to the cylinder head casting. JCS
Big Valve Heads with the larger 39mm stainless steel "Swirl
Polished" valves provide the additional breathing properties
needed to extract the benifits of the performance cams additional
lift and duration.

VW
Connecting Rods
Late style
1600 rod cores are shot-peened, sandblasted and checked
for straightness. New wrist pin bushings are installed then rods
are bored and honed center to center.
Counterweighted
Crankshaft
 In
Hi-Performance applications producing big horsepower the typical
VW crankshaft (without counterweights) causes premature wear on
the main bearings and saddles. The Counterweighted Crankshaft
solves this problem by adding weight (counter weights) on opposite
ends of the rod journal throws...opposing weight that balances
out the entire unit. The crank is then 8 doweled and balanced.
An engine
equiped with a counterweighted crankshaft runs smoother, produces
more power and lasts longer.
VW
Flywheels
 Only
German flywheel cores are first inspected for worn or damaged
teeth, dowel pin holes and clutch disc mating surface wear
to make sure it has not been worn or cut too deep. After
shot peening and sandblasting the seal area is polished,
the dowel pin hole area is faced to ensure proper mating to the
crank and then precision ground and polished to exact specifications.
JCS
110 Camshaft
 Profiled
off the Engle 110 grind (.430 x 284) the JCS reground German cam
still idles smoothly... with just a barely discernible "lope".
Higher lift and longer duration produces a strong performance
boost throughout it's entire rpm range with a low end power torque
increase.
Stock Style Heavy Duty Oil Pump
 Made
from die cast aluminum alloy the pump housing is fully machined
to exacting tolerances. Larger 30mm steel gears provide increased
oil pressure during low speed operation. Pumped oil volume is
increased by 30% - 40% over stock promoting lower operating temperatures.
Double
Thrust Cam Bearings
 Typical
VW cam bearings have the thrust shoulder on half of the thrust
bearing. The double thrust bearings provide an equal
360 degree surface to support the camshaft and control wear.
8
Dowel Crank & Flywheel
The
VW 4 dowel crank and flywheel combination is just fine for a stock
engine designed for reliability and economy... not so in performance
applications. All JCS Hi-performance engines come with an
8 dowel setup (SPG pattern) to effectively bond the crank to flywheel,
virtually eliminating the possibility of wobbled holes or shearing.
Heavy
Duty Swivel Adjusters
 These
hardened and heat treated rocker arm adjusters are designed to
spread the impact load on the valve ends and improve control of
valve setting tolerances. These
all-new swivel feet are the answer for valve wear caused by high
lift cams and high valve spring pressures.
Hi
Carbon Steel Pushrods
 High
Carbon Steel pushrods are heat treated to resist flexing
and bending at high rpm's.

EMPI HPMX Dual 40mm Carb. Kit features 40mm carbs., cast EMPI
aluminum manifolds, chrome top air cleaners with washable-gauze
filters and X- Bar linkage.
