I found a flyin miata turbo manifold in my storage. I am wondering if there is anyway I can tell if it is a 1.6 or 1.8 by looking at the manifold measurements.
Can someone help?

The BP has larger bore spacing than the B6. So, you should be able to tell by the spacing of the exhaust manifold stud holes. Here's a quickie:

Not sure on the measurements, but do you have a stock exhaust manifold lying around? Or an exhaust gasket?
I have a an exhaust gasket from a 1.8. Be very clear on what you're measuring and I can compare.

Arabic numerals are what every English-speaking American uses to express numerals, sizes, amounts, or quantities of many items. I could, for instance, use them to describe the number of good posts you've made on this forum (0).

Making simple math with parts of inches (II III/VIII - I VII/XVI) is tricky regardless of numbering system

XV/XVI ?
Completely unsure of Romans used parts though.

Interesting.
Here is some data from one website.

All the others seem to agree but this one was easy to screenshot and post.
Here is another nice interactive on just for fun.
