Hi, I have read so many things about my engine and I would like to know some things. First my block says only zc, I bout it stright from Japan. Is it better than the stock 1.6 D16a6 in my CRX Si? Is the engine good at all? What are some thing that is a "need to know" about this engine. Just some basic awncers then ill get back with some better questions. Thank, Dan.
