Wassup guys, i'm just wondering about what compression ratio i could expect from pr3 pistons in a gsr bottom end.

I did alittle searching and i've read that it's about the same as ITR's. I'm not positive but would i expect about 11.3:1 or higher?

thanks

We'll need to know what cylinder head too - combustion chamber size has everything to do with compression too.

Here play with the various pistons, heads, blocks, etc here:

This is not an exact CR reading, but a pretty good idea.
