Anyways this question is better answered by a builder, since they will have more trial and error to fall back on. However for starters most manufacturers give you a minimum spec per application. This is typically in the .004 to .007 X bore, range. Stock bore is 86mm I believe. 86 mm is 3.3858 inch. Say you went with the larger of the minimum 3.3858 X .0070 = 0.0237 top ring gap. I don’t know what the stock top gap is, but I would guess it’s about 1/2 or less then the 0.0237

I know that doesn’t really answer your question. Ask 10 builders you might get 10 different answers. You should discuss it with them and the manufacturer.
Cool thanx, maybe i'll wait for someone who's done a little engine breaking to chime in I know Jason's been working on some cool stuff and has messed with an engine. Outside of that I spose calling CP or JE would be the next step.
