Pistons showed up. Thanks again andrew.
Went off to my engine builder today. Talked specs. Going with the following.
.004 piston to wall clearance.
Wrist Pin clearances
Rod - .0008
Piston - .00095
No squirters. Got my ferrari bolts for that.
Shoutout to for the sweet wheels with the lights he sent me.

Water pump shopping.
Looks like I need the following.
Gates cast impeller pump: Gates 42134
Gates timing belt Gates T179RB
Gates idler pulley Gates T42005
Gates tensioner pulley Gates T41031
Snagged them all on rockauto. Still just accumulating parts. Cant do any real work until hailey leaves for nursing school.

What I'd have gone with is non-applicable to you (I think) since all my builds revolve around e85.
But I'd have chosen a softer, 4032 forging (supertech, like 4 billion other miata owners) and a little tighter, because .04 on the 2618 sounds like a tractor when warming up, and might have quite a bit of blow by.
But I'm not judging. becauseracecar

This motor will see e85 for some dyno queen time. But it is a pump gas build.
Got a good deal on the wisecos.
Dug through a lot of the older track threads. And .004 is the go to safe piston to wall clearance.
I'd rather be safe than sorry.

The cost of a rebuild because siezed piston is astronomical compared to the cost of a rebuild because I've got a bit too much blowby.
I also have a big crankcase vent. And a big valve cover breather. So dealing with blowby hopefully won't be an issue.
