The TODA piston isn't actually for the JZA, it's for the SW20, which is why it has a very low compression in the JZA- summat like 7:1. I only posted the info because they COULD be used, but they will never give you 8.5:1. TODA do not make a specific JZA piston AFAIK.

....bollox......scrap all that. My measurements were based on using the stroker crank (90mm) so the TODA MR2 pistons hanging off stock internals will be even lower compression....a 5.5:1 2JZ engine anyone? 4 bar boost...?
