Piping size upstream of the turbo?

Piping size upstream of the turbo?
My turbo (DSM T25) has a 2" inlet. I would like to run 2" intake piping and a 2" cone filter unless there is a reason to up-size it and then reduce it right at the turbo. Thoughts? Opinions? Wild *** guesses?

spool time will be great!
you'll regret it running 2" piping.
probably wont even spool

1) a 4" diameter garden hose with a 2" outlet.

Which flows more water?

Your thinking about it too hard. It's a DSM t-25. Just get a 2 to a 2.5 coupler and put a 2.5 cone air filter on it. Done.
If you want to think of it in terms of flow and ----. If you have a bigger pipe then you'll have a bigger filter. A bigger filter will have more surface area on it which lets air flow through it better than a small filter. The piping size really won't do much in terms of performance.

Many people go bigger because you can't find many filters that are 7" in diameter with a 2" coupler. I'd go with a 2.5" and a silicone reducer. Or a new turbo, t25's are rediculous on a 2.0L.
