Hi K20A enthusiasts, once I had a very interessting discussion with Joe McCarthy how much power could be generated with a stock K20A: stock K20A2 block stock K20A2 crank assembly incl. pistons stock K20A2 cylinder head stock K20A2 valve train OEM cams (e.g. K20A or K20Z1 ones) stock K20A2...

I remember seeing a thread on someone blocking it off but I can't seem to find it. I'm getting ITBs soon for my k24a2 head and I was just wondering how people block the coolant port off? Trying to do it with the motor still in the car so simplicity would be the best!
