Im gonna try to do a compression test lets see what happens, does anyone know what are the normal compression numbers are on rb20det? Isnt 160?

Hey fellas! Im new to this forum n also new to the RB world, what I need is somebody help me out to identify this Rb20 block, not sure if its N/A or T I got the block from a friend but he even doesnt know if its N/A or T.. If you look at where the drain oil feed is at theres a plug but I believe the past owner could had put that plug in there we but thats what makes me think its N/amotor soo besides the drain oil feed how can I tell if its an NA or turbo? Here are some pics.
