Intake pipe size

Hey guys

Im wondering what size pipe i should use to run from the front of my turbo to the airfilter.

The turbo has a 2.5" pipe on the front so im thinking about useing this size as it will also fit well in my cramped engine bay.

Is this size fine or should i use something larger?

Cheers
Luke

go with the 2.5 inch it will be far higher in flow than many other turbo engines anyway due to honda running map sensors you wont have a problem running that size pipping at all!
