im going to use the 01 miata pistons in my escort gt build and was wondering what these would bump my compression too? for my class i race in the max i can have is 225 so wondering how close i will be to that with these pistons.

225 what? your probably about to be put on blast. The compression ratio is common knowledge a very simple search will yield your answer.

10:1 you'll be lucky to break 147whp.

yes i know they are 10:1 but how does that transfer into PSI, the max we can have is 225PSI and i want an idea at where these pistons would put me

Search for 01+ miata compression test results and take the highest you find? That won't answer your question (or really give you a clue) if your head is shaved, you need to calculate that based on YOUR engine.

You'll be well under 225psi.

this is why im asking about the pistons because my head is in the machine shop now and i want to have an idea on how much just the pistons will raise the comp, before i go to far on the head

From the 01 service manual:




What this means in your engine, who knows. But this is what you want to see, right?
