I was orginally going to use a B18C1 engine, head, etc and supercharge it. So far into it I priced it out and almost started ordering parts. But just as I was about to, I read into the B20/ls head and found it would not be as reliable as the B18c1 supercahrger, but more of what I am lookin for. The B20's are just a strong as the B18's, but might be a little more difficult in the end when it comes time to tune them. More mix matched parts I guess.
