H25A, J20A Piston specs
Hi everybody, I posted this in Vitara section, but I think I will get more response over here were everyone can see it.
My name is Art and I'm trying to get some information on H25A or J20A pistons.
My intend is to use those pistons in KLZE(Mazda 2.5 v6 84.5mm bore) with KJ(Millenia s) rods for 300+whp on boost.
To start of I need to know the difference between j20a and h25a pistons, both of them are for 84mm bore with 21mm floating pin. Only thing that i think can be different is pin off center(v6).
The most important information that I need is the size specs for the piston(h25a).

Thanks for looking.
