consider this
What everyone has to consider is that, no civic runs faster than 15 stock. Given that, you must find out what you are running to get beaten by a 15 sec civic. Just upping boost and opening up the exhaust will not get you faster. When you run race gas, you are cooling down the motor so that your fuel fires more effectively. One problem, your car needs to be properly tuned in order to take advantage of that. You may run 14's, but very unlikely if your car is not tuned well. All the guages you can think of are basically needed. Boost, water temp, oil pressure, tach, and even an air fuel ratio guage will help. Gert your car monitored. The Turbo link is a great investment, and there is tons of online help once you get started. You get your car tuned, you run 13's with just racegas and no other mods. The civic's are made as a high rpm car that can run a good mile track, but not a quarter. 15 sec is the fastest I can think stock, but then again, I have a brother with an 11 sec civic, that looks bone stock. (sleepers)---it always helps to know your competition. Get your car tuned, and then you can forget about civic's and start worrying about other GN's. Good luck!
