Can anyone identify these piston/rod's?

Pistons/rod's that came out of an rb25det block. Never seen these one's before and I can't find anything when I look up the p/n. If someone can identify them it would be greatly appreciated.

The rods have 75T in the cast number which indicates they are RB25 de or DET conrods. Will check my piston collection in the morning to see if I can help with the piston identification. But they look like N/A pistons.

They are not actually part numbers they are casting numbers.

The pistons are series 2 R33 N/A pistons if they were turbo pistons the stamped number would be 21U.

Can confirm they are R33 N/A pistons
