1999-2001 2.5rs vs 1999-2000 civic si. Both non turbo, both with out engine swaps. Both cars have put about the same amount of money in moding stock engines. which one is faster in a straight?

so i plan on putting a edlebrock turbo kit. which look at procivic.com and comes with almost everything other then exhaust. some skunk 2 full coilovers for suspension but i wanted to know what else am i missing that could be great to mod a civic. AND DONT TELL ME TO BUY A NEW CAR. I LIKE THIS ONE.

wats faster the 1990 nissan silvia nonturbo vs hondaprelude si 1988 non turbo vs toyota celica 1992 non turbo all stock and in ..drag and drift and track ???

they say CX-7 uses alot of gas, but how about if your not uses the turbo always, driving at moderate speeds , is it still a good buy?
