Hi my name is Jon cummins I just purchased my first rx7 and rotary engine it's a 1984 gsl-se with the 13b I love the car it has 15k on a rebuilt motor w/ 5sp and it's 100% stock but it doesn't have enough power but I'm not sure where to start on this car I have no clue if it the same as the fc or not as far as computer is concerned
