Bore Case for Larger Cylinders

Larger pistons and cylinders is a great way to add more power to your VW motor. Price includes decking the cylinder mating surface.

In order to add larger pistons and cylinders to your VW motor properly, the case must be cut to fit the larger cylinders.  We do a radiused cut to prevent adding a stress riser in the bottom of your case.  We also clean up the deck to ensure all 4 cylinders are perpendicular to the crank and the same distance from the crank centerline.

Vintage Volks does not recomend or sell 87mm cylinders.  The slip in/machine in 88mm cylinders are a good choice, but if you are going to that much trouble, why not go with 90.5mm or thick wall 92mm cylinders.  They don't cost that much more and you get a much better engine when you are done.
