oh dear, have a look at this pic... stock 7mge piston with maybe 0.8mm machined off the compression height. so say, what, a stock height (from edge of pin) of about, errr, 22mm???
aint no way on gods good earth one gets 7mm out of that sucker!! (not without going to a single compression ring anyway!)
3mm would be doable me thinks.. must be wary how close the top ring come to the chamber too, i hear n2o gets a little hot
