Re: piston ring gap (avotegra)
Usually you should have the ring gap specified in the packaging. Usually turbo cars go for .30 on the top ring and .20-.21 on the bottom. (cp pistons)

and i used .022 and .25 for my first and second ring.
theres a formula, its like bore diameter in inches x .0065 or .007

At that rate, your oil will prolly be all over the combustion chamber. Not all rings are made alike, some material hardly expands. I have had Wiseco XX rings on .012 and .013. 2% leakdown and the rings never touched when I pulled it out.
