i have a set of 6 rb26dett 87mm JUN forged pistons, still in the original box, never used. They come with JUN piston rings, pins and circlips as well. These are made by Cosworth and sold by JUN.
selling due to them not fitting my block and i need custom sized ones now
$1600 firm (i paid $1900 from greenline.jp only 3 weeks ago), they are $2200 from JUN distributors in Australia
these run really tight bore clearances and piston slap is not an issue compared to other brands.
Send me a PM for my contact details
buyer pays postage, im in Perth, shipping wouldnt be anymore than $50 i'd imagine
