I found an engine from either a 1990-93 Integra RS. The stamp on the block is B18. So it's a b18, but the transmission is automatic. ALl I really need is the head and the block anyway. However, the motor has seized up. I can get it for about ~100-150$ which I think is pretty cheap. I was just wondering if it can be rebuilt and be fixed. If so, what all would I have to do? Would it be worth it, or should I just find another motor that will probably cost me a lot more.
