IPP's Big Bore Sleeving For Your Import This service is unavailable at this time. There is no replacement for displacement! As you probably know, there is no replacement for engine displacement, and it can only be achieved in two ways: by stroking the crankshaft or installing super-sized pistons. These two methods are combined by "big bore sleeving" to achieve an extremely large displacement increase. To install super-sized pistons, the old cylinders must be bored out and large, thick-wall sleeves installed.  They are heat-shrunk and machined to an interference fit to insure that they are rigid. The new sleeves are then bored out to accept the new super-sized pistons and honed to the proper clearance. We can do "Big Bore Sleeving" to both cast iron and aluminum blocks (the block must be milled after sleeving is completed).  We must have the pistons that are to be used so that we can bore the sleeves to fit. If you do not have the pistons, we can supply them for you in any bore size and comp ratio. Price: $160 per Cylinder (includes Sleeve) NOTE: - Price does not include super-size pistons - Some blocks can be bored to 3-4mm over stock bore. We will sonic test Blocks free for max Bore size.
