What I have, or at least what I think I have is a 3rd Gen ZC. I pulled the heat shield off and found a 92 stamped on the head. I was planning on putting it in a 91 crx but I wasnt sure if it would work since its a 3rd gan. It has grey electrical connectort and the motor mount coming out of the timing cover has studs. I read the tech article and it says the 3rd gen should also have a electrical connector at the eng of the exhaust cam but it doesnt. Also the first number under the engine code is a 3, I read somewhere that if it is a 1 its from a crx and if its a 2 its from an integra, so what did this come out of. So does anyone know if this thing will go in a 91 crx and work.
