Piston Identification
Can anyone identify this piston? I'm sure it's a 9.4:1 as it was out of an early Corolla

My educated guess would be that it's a euro-spec 10.1 piston.
A low-comp 9.4 piston would be dished, not domed, and the 10.3 redtop pistons
have a slightly more pronounced dome and some circular cutouts at the bottom of the skirt.
Furthermore the 10.3 piston would have a 20mm full float wrist pin, not 18mm press-fit.

FABRICA MI DIEM, PVNC!

As Ivan said these should be 10.1 Bigport pistons.

hmmm that puts a different perspective on my future engine build.

Thought I had 9.4:1 so was going to splurge a load on some CP or Wossner pistons - no need to now really...

Thanks guys.
