well i took it apart today, i took a piston out, rod bearings are std also pistons are std.. what worries me is that the pistons have side to side play. if they are move you can hear them hit the piston bore wall..
motor has not spun a bearing should i order bearing in std in acl or clivite or any other brand besides stock nissans. or should i send my crank to get work on?
piston measurements were 85.80
block bore was 85.90
.. my next step is to measure piston ring wear and check for taper or any other wear in the cylinder walls.
i have the fsm for s14 sr.. thats what im following for reference.
my plan is to stay with stock bottom end. but if necessary ill go .5 over and eagle rods and acl or clevite bearing.
