Piston pins came with the JE's and are 98g. So with the 509g pistons and 98g pins I'm @ 607 grams. Add the 523g rods and were @ 1130 grams. I weighted a Mahle 92mm RSR piston and pin and it came in @ 579 grams. With my 100mm pistons and .670" dome it's easy to see the 28 grams of extra weight. I'm calculating a comp. ratio somewhere between 10.5 up to 11.0. I needed the large dome volume to make up for the low sweep volume of the 66mm stroke.
