This pistons came out of my normally aspirated H22A engine. They were designed by RS Machine and manufactured by ARIAS, not off-the-shelf stuff. These are for serious engine building, requires block sleeving. I had them installed on Eagle rods but they fit H22A4 rods as well. This engine was 240 horsepower to the wheel on pump gas with stock stroke. They are in excellent condition with less than a year of use, just need some cleaning. 0.866 in. Wrist pins and used rings in good condition are included with the pistons. I'm selling them because I'm going to raise compression, I'll use same exact piston specs just change the dome height because piston worked really well on my set-up. The value of these pistons is over $600 I'm asking $250 plus S/H. Email me or PM with any questions or pics.
