questions on intercooler piping before and after intercooler....

i’m trying to find the pros/cons of different diameter piping before and after my intercooler. i have a t3 .42/.48 garrett turbo on my stock b18a. does having larger piping after the intercooler affect spool, and what are the pro/cons of having different diameters?

thanx for the help.

you really need to search, ive commented on this subject probably 5 or 6 times.

i have read/searched the turbo guide and threads many times. i was more looking for comments on the effects of larger piping after the intercooler, not really what size is better…

but thanx.
