Are there any performance up grades available for the 1HZ that any of you are familiar with? Such as bigger injectors, or a different cam? Im familiar with P.I.. A lot of people are still preaching that P.I. for a IDI is NOT a good thing. Wayne-O appears to have had good luck with his set up. The claim is that it's to hard on the CUPS. Anything that a person can do to get more power outside of a turbo? I plan on turboing her too, but I just thought I'd ask about other things. Thanks in advance.
