After only 1000 miles, my newly build LS-vtec is broke. Dissasembled and found abnormallity (crack or just a LARGE scratch) in the piston with my cyl walls scarred up. I am planning on boring to 82mm but I am having issues finding 82mm Pistons. I looked at JE, CP, Aries and Wiseco and the only 82mm pistons I found was Wiseco. Has anyone put forged pistons in your LSvtec build? Just looking for advice on what has worked. I previously used Topline 81.5mm pr3 pistons. This will be a non-turbo build, but I would like to use a little nitrous this time around. Thanks

I have 85mm Wiseco forged pistons in my LS/VTEC. Super Dupers from Importbuilders, they work great for me.
