These pistons are designed with by Traum pistons for us. They are available in NA and turbo and come pre cut for 16v cylinder heads. They work with both 8v and 16v and can be used with stock or our 152mm H beam connecting rods. It is not advisable to use them with early b230 9mm rods. If your power goals are under 300whp then stock 13mm rods will be ok.
Our Na piston is 9.25:1 with a 530 head and 10.1:1 with a b234 head.
Our Turbo pison is 8.55:1 with a 530 head and 9.25:1 with a b234 head.w
To order select your stroke (stock 2.3 is 80mm and a 2.5 stroker or penta crank will be 86mm) Then pick from turbo or non turbo.
If you have a specific requirement for your pistons (longer than 86mm stroke, higher or lower comperssion, class specific pistons etc.) please contact us and we can make something for you.
