If you're not going to boost the car, there is absolutely NO reason to put in larger injectors. Ignition upgrades do nothing but lighten your wallet. Pulleys and a high flow cat will be the same waste. You'll get minimal power gains from i/h/e. Go that route if you want do something to the car and keep it relatively driveable and stock-like. Stay away from nitrous unless you plan to get some sort of fuel management.
