Howdy. I was looking to buy an ef and had a couple of questions about the differences between the different models. Is the difference between the base hatch's 70 hp and the dx's 92 horsepower an 8 valve versus a 16 valve head? Does the CRX hf have multipoint fuel injection? I wanted an autocross car so I wanted to avoid the extra weight of the SI models, and i wanted to keep it cheap and do a multpoint conversion, or a full d16a6 swap... Let me know which car you think would be best for this.
