$4924.00 Plus $550.00 Refundable Core Charge
1904 cc Stroker – 74mm Stroke x 90.5mm Bore

The longer 74mm stroke crank produces additional low end torque and requires only minimal case clearencing thus retaining it’s strength and integrity.With the use of special counterweights and balancing this crank  produces excellent low end torque and a significant performance increase throughout it’s entire R.P.M. range.

 All JCS Turn Keys include the wider (23%) Cooling Fan, more efficient ‘Dog House’ style Fan Shroud Housing and Aluminum Oil Cooler Case Cases 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 leaks 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.
ts  that promote a quick,  high heat transfer rate from the valve to the cylinder head casting.
VW Connecting RodsLate 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.

VW Crankshafts

JCS uses only 1600cc style “crossdrilled” crankshafts for it’s superior oiling properties. Cores are shot peened,  sand blasted, then carefully inspected for cracks, straightness and damage to the dowel pin holes and threaded ends.  Cranks are reground to exact specifications,  micro-polished and a thread chaser run on both ends.

VW Flywheels, Reground German or New

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.

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.
