intake or throttle body? need opinions.

So i have a 2010 speed 3, its already got your basic mods, intake, exhaust, HPFP, accessport ect. my stock turbo is starting to go bad so im gonna throw a cst4 with EWG in it, now i can afford either the 4 inch intake (i have 3 inch atm) or the 72mm throttle body to go along with it, can anyone tell me which of the 2 would give me more bang for my buck? or is there some other mod i should be looking for instead?

 

While the CS throttle body flows well, IMO you'd be better off looking at flow balance mods such as intake and exhaust manifolds to truly benefit from it

 

pretty sure exhaust manifold is gonna be out of budget. that being said id probably be better off going for the 4 inch intake rather than throttle body eh? cause as far as exhaust goes its got plenty of flow, its just got a 3 inch straightpipe.

 

I don't know if the 4" intake will give you any benefit for the cst4 perhaps @CorkSport - Derrick or @JohnnyTightlips can weigh in.

From what I know the CS throttle body if very nice to drive with.

 

CS throttle body and 4" intake are def overkill on the CST4. 3.5" will be more than enough even 3" will do that job if you are not in a place with a colder climate. I would go 3.5" hard intake and skip the TB.
