Default Ring end gap!! Help :)

Ok guys I have not been able to find a strait answer so I'm posting now.. I have bought Manley 92.5 mm pistons with rigs and I can't find anywhere that says why my ring gap should be... Shouldn't it come correct from Manley?? Anyways I'm trying to get it together today... So please help thanks

Thanks man I had finally found my sheet like this... Checked the ring gap and the top and second ring are way off... one is way to big and one is way too small... idk what to do... Can they add material to the rings?? I know you can file them... Just can't believe its too big... Top ring is supposed to be .012" and it's at .016"

0.012 is way tight 0.016 is still tight. 0.018 on top and 0.020 second ring would be a good target

This is what I would go with. Even if you do the math just using 92.5mm converted to inches you get higher numbers than 0.0016. Also you can call Manley or email them. They are pretty helpful.

This one is more Subaru specific. Yes it is for 2.5L pistons but gives you a better idea. http://www.manleyperformance.com/dl/...structions.pdf

Yeah I called them and did the math on the phone with them just to make sure I was right and they said that's what it's supposed to be... 92.5mm = 3.642x on there chart .0045 and .0035 for top and second ring...
