Hi I am basically a noob in changing engines and a young honda fan... but I need help at least to know if everything is going to fit. What I got is a 93 prelude Si and the engine is messed up, after 3k rpm's the coolant starts leaking from the head gasket. So i'm guessing the engine was badly overheated and as all honda do, the head probably got bent. I decided to go with a more powerful engine so I bought a H22a1 block. if somebody did the same thing please tell me what you had trouble with and what parts to I need to buy. so far I know that i need a p13 ecu and stock headers from h22. what else? thanks
