If you need just one piston try this mob:
JP Engineering Home Page
They make pistons to order, in house.
If your piston broke I would inspect the bore extremely carefully for cracks first, though.

So if I got a 20thou oversized datsun 180B or 200B would it fit the 80thou bores? I'll send an email to JP Engineering and see what they can do. If I can I'll try to avoid running 20thou too small pistons I don't really want to do that but If I can't find anything I may have to cause I don't want to leave it sitting there doing nothing. As for the Blue or Black motor there just isn't any around where I am that are for sale or under $500. I was quoted $500 for a Red 202 that was stuffed from one wrecker which I thought was a very rough deal. Me and a mate where thinking of getting a Series and either dropping a V8 in it or a 3.3 Turbo Diesel from a Patrol as a cheap farm and hunting vehicle so thanks for the info on the 253 with Nissan gear cause thats what we were thinking of doing.Quote:

If we can find a cheap option for an engine here at around $100- would that be an option?
Geez, that is rough. It doesn't seem that long ago that you could pick up a decent runner for a slab of beer...Quote:

Well I picked mine up for free which was good but it's got problems. I think I might have to get another block or something cause everyone I've contacted can't help me and the internet has nothing. I don't know what to do now cause that lip on the bores isn't carbon:( Do I find another 202 block and pistons to suit that block then transfer the crank, cam, head and other gear over or find something else and sell the motor in bits. Tough decision. I'll keep trying but it can't eat up too much money. The 180B and 200B aren't the right size and I couldn't find anything the right size. I spent $120 on fuel and stuff like that, I'm going to ask a few people on a few farms around here about what the have and see what I can find. There is a very very rusty 186 sitting in the front paddock but I don't think you can use 186 blocks with 202's.
I think the 186 is a better block it was popular to bore them out to a 192 back in there day and they seemed to take a bit of abuse, if no water has made it's way into the 186 it would be worth a go as there getting hard to find around here, if you can get it for next to nothing would be worth it.

The 186 is generally agreed to be a better unit. Still lots of bits available, ebay is your friend. Everything will fit, not sure of head though. By memory they all fit (173/186/202) but you may need to check the water/oil ports and maybe drill the head gasket to suit (and maybe a oil drain port or 2).
There's talk of compression differences but the chambers are the same volume between the three, earlier are smaller but there's too much difference in bore size so there's other issues with chamber shape and squish areas.
I spoke to the owner and he said he'll take $300 with or without the motor not sure if that's a good deal as it's looks pretty weathered and the condition of the box and T case are unknown until they can be tested out.Quote:

Auto 1 are going to give me a ring and let me know what they can do so I hope it all works out. I read you can't use a 186 block with 202 crank but not sure.
I would be checking the rest of the bores very closely with a block at 80 thou over, especially if there is a big lip at the top of the bore as you say. Spending money on a big over bored worn out engine may not be such a good ideaQuote:

You may even find buying a whole car, early commo or rusted out h series, torrie may provide a decent engine you might even then be able to hear running or even test drive the engine.
