I have a set of Mahle forged pistons and liners, complete with bushed, full floating, balanced rods for sale. Three of the four pistons have small cracks in the pin bosses due to a machining defect. They might last 5km or 500,000km. The pistons have a raised crown. Compression ratio on a std. S1 head is 11:1. The crown can be machined further to reduce the CR.
