You don't need to change engines to go Turbo. Just buy a turbo kit for your existing engine. The B16A2 that you have in that car is one of the best Honda engines ever made.iShIi said:Hey, I was wondering what turbo engines people are using (if at all) on their civic SIs. I have a black 00 SI and I am interested in switching to Turbo. I heard somewhere taht Vortec makes a good engine for my car... is taht a myth?
