i realize that most turbo kits come with an intake that probably fits well with the turbo and manifold but are they nesacary? i have a j's racing intake and i dont want to ditch it for some cheapo intake included w/ the greddy kit i'm looking to buy?

 

is the j's racing intake just a filter? if its not you wont be able to use the j's racing piping along with it, because the intake goes connected to your turbo's compressor side, not the throttle body
