SOMETHING FOUND OUT , you kno if you put the b18c1 into a 92 hb there will be a gap of a few inches inbetween the exhaust and the header? There IS a stock honda part that can just fit there so you wont have to go get some other piece welded. I found this out while in the bays of my garage, ther was my car in one bay and an accord wagon, the 94-97 model, in the next bay. while looking under i saw that the piece between the header and the exhaust is the exact piece missing from the civic/gsr swap, just wanted to let you guys know this. Sorry if this has been posted already
Peace
