what's a good higher compression ratio for an n/a d16y8....maybe buying pistons open to suggestions
Yup. That's a good way to go. With the VTEC head gasket you'll be at about 12.6:1. That's the compression ratio I would want to run. Drop a Crower stage 3 cam on top of that and you'll have tons of fun.
will they fit without a bore? with the same rods?
Yup, same bore, same rods. You'll want to check to make sure your piston to wall clearances are in spec though.
i'm not real inclined to the termanology for pistons...other people do my work for me...how exactly do you che the wall clearances?
With a gauge...
if you have an engine builder (since your not too familiar with that), they should do it as part of the build. Its just one of those standard things that most people in their garage fail to do....basically just check all clearances and make sure they are all to spec.
The machine shop usually checks it for you when they match bore your block to your pistons- at least that's the right way to do it.
i thought no boring was involved...or is that just boring for the oil?
No boring to remove large amounts of material- but you should always have a good machine shop match the bores of the cylinders to the pistons. That way your piston to wall clearances are always in spec. It's much easier to do when you go one size up from your current sleeve bore size, but it is still doable with a new set of pistons running the stock bore size.
