well i just got my 01 gs integra and i want to get a turbo for y car, do i need to replace some stock internals before i do the turbo, and i already have ordered the greddy evo catback exhaust and tenga r intake. so i really need alot of suggestions and help on what i should replace or keeping stock

 

DO some searching.

Why did you order an intake if you are planning on a turbo kit?

 

i was given that intake by a friend in which he had on his old teg, but the exhaust is the only thing i have bought
