There is a 1990 CRX Si with a DOHC ZC swap for sale in Miami that I am thinking about picking up. The current owner has the manifold and turbo from the D16 Greddy Kit installed and running on this car. He claims "it bolts right up, no modification" but from what I have read, the ports are actually shifted from the ZC head and the Si runners. This car is in fair exterior shape and the interior needs some TLC. I don't even plan on running this car as-is, rather tearing it down to throw in new rods, pistons, and to try out Hotrex's Devcon special (and obviousley running a much larger turbo). I would plan on running an OBD0 -> OBD1 Harness so that I can run Uberdata (it's what I know, I'm not sure about running BRE or Turboedit). This is subject to change. I plan to do all my own work to the best of my abilities, I am no fabricator by any means. The questions: It's hard to search on ZC engines, as most forums don't index "ZC" because it is just 2 letters. What are the particulars I should know about ZC engines? Internals mean nothing to me because I plan to replace them. Does the head have a tendencey to lift? Does the deck warp often? Should special considerations be made with the transmission? I would need a turbo manifold to meet my goals (300whp on a built block, stock head). I'm guessing that the manifold he is running is creating obscene EGTs. Who makes one that would give me clearance to run a .60/.63 in a CRX with a traction bar? (jimFab, Z10, Full-Race) I'm assuming I'd modify an LS map to run the ZC. Is the ZC Peak & Hold or Saturated? I'm just trying to get a feel for it before I put down any cash. The main thing I hated about my Prelude is that there was no support for H23s and I'm not a tig-welding wiz. I don't want to be in the same boat with this ZC.
