Ok, here is the deal. My dude bought a 12 second civic coupe that was a straight up drag car. He was told that it had aftermarket pistons and rods in it, but he was also told they were pulled. The wire harness was cut, and everything in the engine bay was made pretty useless. So we figured that the previous owner pulled the engine (cutting everything) and removed the pistons. He also removed the cams, cam caps, and anything else that would make this an easy motor to get running again. The block is a d15b7, and it has a d16a1 head on it. So we randomly decided to pull the head. We were shocked to find the pistons were still in it. The block looks as if it has been bored and honed. The head gasket was badly blown. But as of right now, (we havent pulled any thing else apart) the only thing we can see are the tops of the pistons. They are flat top, with valve reliefs on them. The only markings i can remember on them are Pr3, and 8.0. Does anyone know what kind of pistons these are? and if they are a stock piston, or are they aftermarket? I am building up my own Turbo D, i was hoping to get into the mid lower 12's with, and this may end up saving me time and money if its still built. At the same time i do not want to pull the pistons and rods out if i dont need to. I will get pics later.
