Thanks people,
I'll end up boring a new block but I found pistons.

You can try Egge Obsolete Engine Parts ( http://www.egge.com ). They specialize in olderstuff you can't get anywhere else, but mostly American cars. If all else fails, they're worth a shot.

Sage advice.
Any leads on piston manufacturers that still inventory old civic pistons, oversize or std? I suppose I can always bore another block if I can find std pistons.
Thanks

Well if you want some mega cheap pistons, you could use some from a Suzuki Swift. Not sure exactly which model (you should be able to find out without too much trouble). Standard bore is 74mm so oversize shouldn't be a problem to get and pin size is correct. You need to skim a mm or two off the crown. The problem for you is they are flat top (with valve reliefs but they are in the wrong places). I doubt they would have enough meat in them to take off more than just enough to get them down to the block.

Also don't forget that just looking at the top of the liners to see how thick they appear means very little as they are ribbed on the outside, thus the apparent thickness at the top can be deceptive.

This is an EB2 block that I bored to 74 mm with a 1335 crank and rods that I built in 1985 (180 psi cyl pressure). The cylinders have a bit of taper now so I need to go oversize again. It will clean up with a .25 overbore but barely hence the search for .50s. I agree the liners will be thin but I had quite a selection of blocks to choose from then and we chose the one with the thickest cylinders. This a torquey street engine that stays below the stock redline so I’m content with cast pistons (plus, I’m a cheap bas#*d).

If you are using a stoked bottom end (1335 crank and rods) with an eb2 head, you should use flat top pistons to get a 10.0:1 cr. The dished pistons will have a much lower cr. If you want a set of the cvcc dished 74mm pistons, I think I know where to get a barely used set with rings. They are on the cvcc rods but they can be changed.
Let me know.

74mm is not.5mm over size its 2MM over size. if you go another.5 you had better have the cylinder walls checked sonicly. Custom forged pistons there is no reason to use anything else. Venolia has a 1200 piston that can be customised to your specs

Confused ....
Are you trying to find 74 or 74.5mm pistons?
74mm (2mm overbore) is pretty much the limit for the EB block. Bigger than that and the walls start getting VERY thin.

Adrian, Don, Errol....?

OK knowledge pool, I’m looking for oversize (pref .5 over) 74 mm dished pistons (and rings) for my old EB2 stroker. My local suppliers can’t come up with any. Any help appreciated.
Thanks
