93 del sol with a b16a1? did you swap the engine or are you in europe or something? I'm confused. 94-95 in US was a b16a3 then 96-97 was a b16a2. anyway, airdale you confused me with labeling everything in feet. If you're going turbo, I'de wait until you have everything set up with the turbo installed so that the exhaust fits correctly. other than that if you're going n/a get a header and a catback.
