I've got a 1986 Mazda rx7 base model, I'm "power crazy" at the moment! I did everything here and there to increase horsepower. I change my factory air box to a cone air filter and did a open exuast with Top of the line NGK sparks plug have to offer. I also advance the timing and Im about to change the headers. Basically my question is what can I do to gain more horsepower with out droping a turbo in there. Im willing to buy what I need but Im still confuse on what I need to gain more power. I know my basic on rotary but not as much I wanted to know but still I need to know what is out there that I can drop on my fuel injected 13B. I know I cant get as much Hp as a turbo but enough to dust a budget v-tech....
Thanks for any suggestion.
