Im wantin to mod my rx7 n/a. I am not sure if this is in the right place but here I go. I know I am gonna need some new apex seals soon and I was wandering if there were some stronger seals that I can get to protect my engine better? Also I was wandering what all I can do to make some more hp. I figured if Im gonna have the engine apart then I might as well do some things to it so any sudgestions would be appreciated. I was wandering how much more power I could get out of the engine street porting it and what else I may beable to do to get 300is n/a.

 

If you are rebuilding the motor, you would probably want to put a street port on it. Also, I would probably rebuild with stock Mazda's Apex Seals especially on an NA. Then look into getting a header & exhaust system from Racingbeat .

 

Im tryin to get atleast 300hp out of it. Its gonna be a show car but I also want it to have so go. I was wanderin about the aftermarket seals cause I was gonna turbo the engine later and maybe spray it. As for the street port how what exactly is it and about how much does it cost and can I get to 300 with the things you mentioned. I found a nic headder by pacesetter and there is a locka shop that can run the pipe off the header for me. Also I was told that a "unstreetable peripheral port" would be better, what is that too? Im not new to the rx7 just new to moddin them. Im tryin to figure out what I can do to get the 300rwhp and see what its gonna cost.
