ok, so i have an 87 non-turbo rx7, i'm looking to begin some after market upgrades. it is completely stock other than the exhaust, brakes, and tires. looking to gain horsepower what is the most "bang-for-the-buck" thing i should add? intake? headers? what would you suggest? i'm looking into possibly purchasing a short shift kit maybe. this car is flawless interior and exterior. now i'm looking to add some "go" to the "show". thankkkssss

hi steve,
welcome to the site!
there are lots of mods and upgrades that you can do to your ride.. you can install a good muffler, header, intake... as to muffler choices - there is borla, magnaflow, flowmaster, etc, there are lots of aftermarket mazda parts that are available in the market.. it would really depend on your choice as to what to install and the $$$ you are willing to spend on..

 

yea the first thing you should do is put in a new turbo system. and when you put in a turbo kit, you need to change the headers, exhaust, and maybe the fuel and ignition system in order to prevent detonation. you could also put in a brand new rotary engine already turboed or put in a racing rotary engine...
