I have a 85 RX-7 w/ a 12a with a racing beat intake manifold, holley 465 carb with the mechnical secondaries set to open all the way at full throttle. Also, monza headers and muffler assembly with all other piping replaced with new 2" pipe. rats nest removed, air injection removed...I guess thats it. How much Horsepower do you think that would be? Also does anyone have any suggestions for a good next step to give me a little more power? how much is streetporting? thanks in advance. ~Tim.

 

well, streetporting involves rebuidling the engine. soooo, that might not be your next step LOL next on your list should be IGNITION. if you wanna stay on the cheap, do what some of these guys are doing and rock an FC leading coil pack. easy direct fire. since your n/a i'm sure it will help but it sucked the big one for my setup. i used an msd box and now the car breaks the tires loose just flooring it in 3rd it never did that before the msd. BETTER SPARK = POWER. after that, enjoy the car a bit, and maybe save up for that rebuild.


oh yea, i'd say your around 115 - 120 Rwhp.
