hi im just looking for some ideas on what i can do to my 85 civic, it has an engine out of a 91 crx or at least thats what the book that came with the car says thats got about 50000 miles on it, i know its carbed and its a 12 valve engine, the car dose have a 5 speed so that kinda helps a little, but i must say for a 4 cyl. it dose do pretty good for being 19 y/o, well i hope someone can help me out thanks.....
