Please help identify these pistons in shortblock i purchased

[SasaniFab]

so i just purchased this shortblock off of craigs list. I know they are 2g but what does the 0.5 mean in terms of size? 85.5 mm? The pistons read 63dtf1 with a small 0.50 near the letters? Im assuming 0.020 over?

They're stock NPR's as I recall. I *believe* the .50 means a .020 overbore. But check them out with a caliper to be sure.

Thats what i thought , im gunna take the engine apart and bring it to a machine shop...

Yup stock 2G turbo pistons.

Just what everyone else said, Stock 2g pistons 22mm wrist pin

.50mm or .020 over

Should have a grey coating on the piston crown
