I think they are from d16a1 motors?? not really sure.. but plz make offer and lmk...thnks!!

 

PM7 is what you are looking for....from the brown top ol school Integras???

 

i have a set of pm6 from a D16a6 and a set of pm7 from a dohc zc.
your looking for the dome top right?

 

Yea thats the one... it has the same measurements as a stock d16z6 right?

 

your looking for the flat top older 86-87 d16a1 motor pistons way better design than the p29/pm7 what type of setup are these going in? you may have clearance issues pistons may need to be notched for valve clearance. I have done my research on this setup and im going with a 1mm oversize pm6 pistons welded z6 head so about 11.1 compression and here is a nice set for cheap http://cgi.ebay.com/ebaymotors/ws/eB...%3AMEWAX%3AVRI

but if your looking for good power id rather go with a larger piston than more compresion

hope this helps lol

 

Thanks for the info...looked up the pistons..going for an all motor setup. Its a DD.Just looking to replace the pistons. are these pistons dependable since its comming from ebay? lol........sounds good.

 

ya you can get good things on ebay but i would go with a new set oversize .20 over to freshen up the cylinder walls and get that extra displacement well worth it but will cost you some money to get the cylinders bored by a machine shop.
here is a good set/good quality with rings http://cgi.ebay.com/ebaymotors/86-87...Q5fAccessories
