I currently have a B20/GSR head swap in my 2000 Civic EX. I was able to get AC back, but I've been without PS for a while now. I've looked up on a couple threads about which top bracket I need to get. Some have said del sol vtec, gsr, or any vtec ps bracket. As far as I'm aware, all bottom brackets are the same. I need some clarification before I go ahead and buy the wrong bracket.
