I was under the impression ALL nissan turbo motors are 8.5-1 stock. Im sure they are.
Tell you what though, the guy who built that motor is kind of an idiot. The N/A sr20 bottom ends arnet built as much as the det, like no oil suirters and rods that are not as beefy. I know because i have an sr20de sitting in pieces right here. . . .

All he had to do was change the pistons or use a Tomei .6mm head gasket. Both of those would have had the same effect. . . .
