I am about to boost my stock b18b and i was planning on getting a edelbrock victor x intake manifold and was wondering what sized throttlebody i should get...

 

u should be fine with your stock throttle body. Unless your charge pipe is going to be bigger than ur throttle body, i dont see a point

 

I think aftermarket throttlebodies performance are negligable when going with boost...
EXAMPLE
15psi turbo b16 might make 300whp
15psi turbo b16 with 68mm throttle body might make 305whp...
Stick with the stock TB and spend the money on something that will get you more power like CAMS,FULL EXHAUST,TUNING TIME
