im measuring my piston to cylinder wall clearance on my sr20det and i end up with an average gap of .0025in i am aware that oem nissan specs are .0004in - .0012in Ive heard of setups with gaps of .0045in with forged pistons, to me that seems like alot even with forged pistons expanding. i wanted to know if you could go any further with oem pistons safely and reliably?
