I'm not sure why you are referring to a comp ration of "9.0:1" because compression ratio is not determined by the size of the piston alone. Compression ratio has to do with deck height, head cc, bore size, etc.

I found the following website helpful: http://www.csgnetwork.com/compcalc.html

Also, I believe Jake's store (type4store.com) may sell individual pistons. You will need to consider which cylinders you are using as well, and a set of rings will be needed (if a new set doesn't come w/the 3 good pistons). What seems like a deal on the 3 pistons may end up costing more than you'd think after piecing together the rest...

I've been through this a few times - both the hard way and easy way (see my avatar). But I'm certainly no expert.

A 9.0:1 piston would be one which gives you a 9.0:1 compression ratio with a standard head.

Which standard head, 1.7L, 1.8L, 1.8L AMC, 2.0L? Either I have spent a lot of unnecessary time with my micrometer & laptop calculating CR or there's some misinformation going on here.

I'm pretty sure Mike is looking for the standard KB 96mm piston BUT he's going to be very disappointed (or just not know the difference as ignorance is bliss) that by just replacing his current p/c combo with the KB 96mm does not necessarily give him a 9:1 CR. CR is a bit more complex than that - by no means is it witchcraft or voodoo but there's a couple other variables involved.

I'm just trying to save someone some time/effort/$... I learned the hard way that not everyone on this board knows what he is talking about. CR cannot be spoken of in vague or "standard" terms b/c as Andy states - most heads have been modified or rebuilt at least once by now and "standard" is a unicorn.
