Im new to the Honda world, and I love the 91 CRX Si, and one of my friends told me about the ZC motor. Until that point I had never heard of it, I also know that aftermarket products for the engine are scarce. If i were to get a ZC motor put into a CRX, what limitations would I have as to what I could do? Does anyone produce aftermarket internals for it? How does it compare to a b18c1? Thank you for your time.
