My build right now I am looking into doing is a questionable one. I am trying to do 1 engine form 2 different types. The B6 engine Block with the B6-ME head. I think they are the same. But I am new to Mazda engines. I don't know a lot about them I just know they have good cars. I am more of a 3 cylinder DOHC fan. Yes they do exist. Daihatsu Charade Gtti. For those of you that don't know. Its also the only 3 cylinder with a turbo as well lol. But the reason I am here. I want to do a swap in my Festiva. Yes I know I can use ford engine's but that is not why I am here. I would like to use the 2 engine's below. But the B6 block is what I was going to to use for an engine. But I was thinking that if I did the other one. That it might be the same block but different. So my question is can I combine parts to make a engine that I do not have to do anything to the Firewall. With the B6 its a bolt right in. With the B6-ME that one is a hammer or weld in on the firewall. But if I am right on this. The B6 is a direct bolt and kind of wire in. But with the head is smaller than the other. I was thinking that I can use the other head. But if I did that would that make it a B6-ME or a B6 with a 16 valve head. I was hope to find out on this build. But Not sure if I can do it or look into just doing one of the swaps. Well let me know all. But please don't flame my question.
