Hey there fellow luders. I thought I'd introduce myself to the forum since I've been leeching for valuable information without posting anything. Been an owner of a '91 Prelude Si B20A for about a year now on and off with a couple breakdowns and issues with smog. I recently got it up and running smoothly without it dying on me. Still has some issues but I don't want to rush ha. First question though, why is my engine a B20A? No A3 A5 just plain A. If any of you guys know I'd really appreciate the knowledge. Thanks in advance, I'll post a pic.
