Hi all! I am the proud owner of a 1991 CRX with its original ZC motor. D16A9 to be exact. I am looking for more power. Actually I want something more torquey. That is why rather than spending money on bolt-ons which will give me only small gains, I thought I'd save it up and do a complete swap for a motor with more 'potential'. ZC is one hell of a motor. It is a beast for what it is. At first I thought I would modify the hell out of it but I was discouraged by the fact that you can't even get cams for ZC anymore. HKS used to make them but discontinued now. They are expensive, too and you can't expect much from just cams and some bolt-ons. I want something with more potential like a B16A2 or a B18A2. I even thought of Frankenstein motors but discouraged again after a few firends told me that I wouldn't be able to use the potential of VTEC head and powerband of aftermarket VTEC cams. Parts availability was another problem, too, so I am left with two options here ---> A B18A2 out of a 91-92 LS or a B16A2 out of a 92-96 del Sol or a 96-99 Civic VTi. Which one would be easier for me to have done and which one would you recommend? Part of me wants the torquey B18A, and the other part wants the more-tunable, better-aftermarker, higher-revving -but relatively torqueless- B16A. Which one, guys?
