The rings that came with the old old NOS MTC Engineering big bore kit are Hastings rings that, after researching from seeing a permanent-marker-blacked-out Honda/Nissan designation on the box, fit a 1971-1978 Honda Civic engine! At least I can get rings without having to custom order anything, if I could find rings for such an old Honda engine. I find it shocking that Hastings would make chrome rings for such an economy car, but it definitely says chrome on the side of the box.
my big concern is that a chrome rings are incredibly hard from what I have read, and much more difficult to break in. The machine shop guy looked at the box of the rings and I think mumbling something that was probably referring to the chrome, as I believe you use a more coarse hone when honing the cylinders for chrome rings.
what is to be expected when trying to break these things in? I was planning on 20 hard miles of accelerating and decelerating to break in the rings, but it now sounds like I should spend at least 30 or 40 & ride it pretty darn hard for a few hundred miles thereafter.
Any advice?
