Isuzu G-series Twin Cam

hey all does anyone know what pistons i can use for a g200w dohc, i dont want anthing oversize i just want replace the original pistons. ive been bashing my head against the wall tracking down parts all i need are pistons.
i have a g200w dohc engine in a te gem running 10.4 1/4mile this engine was eazy to build but has not one standard part in it now all i want is too build up a standard one and cant find shit for it if anyone knows what pistons please please HELP!!!

Do you know what size in mm the bore is cause i think i have a standard set at home but they could be out of my 1.8

yeah i got some im buying some vernier calipers soon so ill be able to measure them up for ya and make sure they are standard

Bore/stroke is the same as that for a G200Z engine. 87mm bore and an 82mm stroke.
