Ahhh...so that's where the initials JDM come from. I'd just assumed it was a company name. And yeah, the engine's JDM.
So one last quick question - even though I'm almost definitely going to do a swap (and thanks for the

btw), is it even feasible to just buy a single piston/ring set from partsdino or another company and spend a weekend reaming/reboring cylinder 3 and replacing the damaged piston and rings instead of swapping the whole engine? Or will the cylinder itself have been damaged? I inspected everything thoroughly last night after I'd pulled things apart and cleaned them, and the rod and bearings look like they're ok - it's just the piston itself apparently. And the other two cylinders' mechanisms are in incredibly good shape for being 15 years old. Heck, after I put the thing back together, other than the knock from the already damaged piston the engine sounds great. It almost offends my senses of thrift and fairness

. I'm curious mostly, although DOCTORBILL's experience seems to suggest it's possible and I'd love the experience and satisfaction of doing open heart surgery on a car (I'm a biology scientist by trade). But if we're talking about something that would take more than a weekend (assuming 2 full days to work on it) I'd rather donate some blood and sperm and just pay to swap the engines.
