I have just recently purchased a 1993 Mazda Rx-7.

I was wondering if there are any "cheap or non cost" tweaks or mods you can do to the car, to free some extra hp and or any ideas to quickly and easily reduce some weight?


Please post your ideas, or what has worked best for you.

 

cheap isnt always the way to go with fds.
you could always do the fan mod, or fab a heat shield for your intake if your running an aftermarket intake.

 

Performance isn't free.

As far as cheap things to do:
