Minimum to replace rods
So, I'm wanting to go in and replace rods in my engine.
I don't need pistons, oil pump, or anything else as all I'm looking for is ~250rwtq max. I'm just looking for a /very reliable/ 250rwtq, nothing more.
What's the bare (sensible) minimum? Rods and bearings? I don't think honing is required if the same pistons go into the same bores.

Smacking myself for forgetting the head gasket on my list, thank you Neilv. Although I have a set of FM clutch bearings in there with < 5k, so I think I'm good there. Engine has ~100k on it, so I'm fairly okay with the rings considering compression is good.
Thrust washers worth replacing?

Cheapest I've found is closer to 150 - at that price, I am probably going to jump on them.
(Edit) Well, I guess I could get no-name autobone rings for $125ish + tax....Is where I am just unusually expensive or what?
(Edit^2) Holy ****. Online sets of piston rings are half the cost of suppliers locally. Thanks 18psi, I'll probably be picking rings up.

One part in particular is a third of the price locally!

RockAuto has rings for stock pistons at $35 for a set I believe. I know for my supertechs a set of replacement rings were about $100 from TSE. If you are trying to go cheap I would say pick up an engine rebuild on ebay here. Then pick up ebay rods for like $250 and then you are at about $500 in rebuild parts cost.

I like your idea a lot, Shoes, and wish I would have done it from the start. Already got a timing kit to go on though.

So, what's the difference between stock pistons and these steel topped pistons:
94 97 Mazda Miata MX5 1 8L DOHC BP Engine re Ring Kit | eBay
? 'Cause that is kind of tempting to pick up - oversize pistons, MLS everything gasket-wise, and I can bore the block myself or get a mechanic friend to do it for me for cheap.

I was wondering/planning to do the same thing.
My buddy who's built a few engines said that if you pull the pistons out of the cylinders there's no way they will go back in and get a decent seal. He recommended strongly to do a re-ring. If I do any of this (rods only, keep pistons) I will be buying one of the ball honing tools to do a quick re-hone.

Secondly, as I mentioned above, I don't want to put anything high dollar into this first rebuild. I am looking for Cheap **** I can break and not panic going "Oh ****, those were $400 pistons!!!"
