My friend just gave me a ZC a couple weeks ago cuz it was taking up too much space in his garage. I plan on building it just for the hell of it. Don't plan on putting it in my car...i got a b16 for that..i just think it'd be fun to build..maybe buy a hb and throw it in there..or sell it. I don't know anything about these old motors..Do companies like Je or Crower or Skunk2 or any major brands actually produce parts for old motors like this? I believe it is a DOHC, but since it is just the bare bottom end w/ no head..i am not sure. How could i find out if it is SOHC or DOHC? Or could i just buy a head for it that is DOHC? Also, i read the article on how to build a HF monster..and i was wondering if there was some kind of trick to building ZC's in the same fashion (using cheap stock parts off other cars). If not, where the hell can i find parts for my motor? Keep in mind, i don't want to spend my entire B16 budget on this damn ZC, just wanna build it for fun. Btw, thank you B for the info about how to obtain information.
