civic question

how fast would a civic get wit a t3/t4 turbo with about 10psi of boost ...... also would i need to do any mods to the engine to run that boost????
i am wounderin cuz i am lookin into buyin a civic

there are a ton of variables that are in question. no one can answer this question for you.

What year civic? You would be better off going with an SI as opposed to a D series especially if you are thinking of boosting.

it is just an 03 st and its sohc which kinda sux

Save your boosting money and go with an RSX or SI, you'll be happier if you plan to mod in the future.
