Have two sets of Wiseco Pistons brand new in the box. One set is 86mm 11.7:1 compression for the K20A2. Pretty standard. The other set is a set of Wiseco for a K20A2 head with K24 bottom end stroker. THey are designed to deliver 15:1 compression ratio and have been coated both on the tops and the skirts. These are some wicked pistons for a race motor application. $400 for either set shipped. First pic is the standard set, second two are of the race pistons and it's spec sheet.
