piston info??
im looking for info about pistons
i have a b20 block and want to run a gsr crank along with some forged gsr rods. my only question is since the stroke is different i need to have some sort of custom piston if im not mistaken
if anyone has built something similar any help would be appriciated
here is the specs on the pistons im looking at
Honda SC7021 B - Series 3.327" / 84.5mm +.020 / +0.5mm 1.181 9.0
im wondering what the numbers all mean??
thanks

Re: piston info?? (AK94GSR)
Someone with a bit more knowledge will have to chime in, but I can tell you some info.
84.5mm is the diameter, +.020 is how much it varies from stock size (I want to say the unit is inches for some reason it escapes me at the moment).
I would guess that the 3.327" would be the height of the piston and the +.5mm would be the height of the dome. Just a guess though, someone will need to verify that.
