what edo means is 87.5MM pistons (not honing to 87.5mm and keeping the 87mm pistons)

personally 87.5mm is kinda big for the stock liners, they aren't any bigger than 1/8 thick, then the aluminum deck pretrudes.. not much force left for sidewall loading....

machine shop said 87.25 at most... I don't feel like being a test dummy at 87.5mm I have enough bad luck as it is..

I lesson learned the hardway, waiting on manufacturer to see if he can accomodate a set in a serious hurry.

so 87mm pistons require aftermarket sleeve size to run. OEM sleeves are honed to big for the forged units..... my block was new, no out of roundness also.

from the looks of things it's only Ron and myself doing complicated builds ???

sc7147X, my TSX block was at 5thousands, spec requires 3.. get a feeler gauge and mesure it, because i'm pretty certain all k24's will have the same result.. so yeah those who have thos pistons well.. were kinda all SOL.

so those who have these pistons please mesure and provide your feedback aswell.
