I was set on 2.5", but many turbos come with 2" outlet.. so i thoght maybe to run 2" from compressor to intercooler, then 2.5". how much of a difference is it really going to make on b series aiming for 300-350whp tops

I run 2" from turbo to intercooler than 2.5" from intercooler to throttle body. HP is in the sig, its been working well so far.

I like to use whatever the turbo outlet is for the piping to the IC. From the IC to the TB generally varies with the size of your IC outlet and TB bore.
