i'm building a zetec turbo engine and all that will be built in the next couple of weeks, i'm aiming for around 400bhp, but not sure what boost pipe size to go for.
i was thinking 2" as compressor outlet is 2" and intercooler fittings are 2" also.
intercooler may need to chage for a bigger one so that could change in time.
but is there any reason to use 2.5" boost pipes instead to help flow or will the bottle neck of 2" be the restriction and bigger pipes increase lag too much for the potential flow gain?

cheers for any useful tips on this subject.

anyone got an opinion on this at all?
i would have thought 2" would be enough for now at least.

Sean, start a thread on this subject in the general car related section, it'll get a lot more views/replies.
