Those are really the two best options.. It will cost some $$ but it IS worth it. If you dont want to go crazy hardcore with it though I guess you could upgrade the ignition with a msd 6al and blaster 2 coil or something. There is also cold air intakes you can get.
If you want to get a little more hardcore with it you can always put a 50 shot or nos on it or something. I hear that if they are done right you are fairly safe but I still wouldent trust them, Plus you still have to fill up a damn bottle. If someone wants to race youll have to be like "Hold on I have to turn on the horsepower" and get out and open the trunk and all that nonsense, its just silly.
Getting a turbo is the best thing to do. Do some research on the bpt from the 323 gtx's (familia) and see how much trouble it is to swap. I did it and it was totally worth it, espically when you are faster than most v8's. :p
