Musada

Hello, i have an 86 and an 88 Mazda Rx7, both non turbo. And i am kind of new with rotary engines and was just wondering, if you new of any sources that gives some kind of guide that can help up the perfomance of my car. Well any advice you have would be greatly apprecited. Oh yea, seeing as i am only 19, working at Pep Boys and in college, cash is pretty limited so i gotta start out small.
