If you were purchasing intercooler couplings then a 2.5" would do just fine. Since the thin wall of the piping is taken into consideration. Using a fernco coupling from a harware store you would have to get a 2" due the the wall thickness. The inside diameter of the hardware store 2" coupling is just slightly under 2.5"

omg this is getting out of hand lets end this thread.....lol....ps just go get a damn silicone coupler it will be worth it in the end they last alot longer

Luckily your opinion of me isn't what gets me out of bed in the morning.

You can still buy from eBay just like I can. I'm on a budget too, and I like finding cost-effective solutions, but that doesn't necessarily mean finding the cheapest way possible. The fact is your $20 TID (which I assume is made of PVC pipe fittings and plumbing couplers) will not flow nearly as well as one made from metal pipe with a proper reducer. Low-velocity water doesn't care about sharp internal corners and protrusions; high-velocity air does, particularly right at the compressor entry. Apart from that fact that it looks like ***, I'm not prepared to make performance compromises like that just to save a few bucks. But that's just me...

Holy crap people, most of you have the learn how to use a dial caliper, as it's the proper instrument for measurement in this case.

NZConvertible is right - the proper O.D. (OUTSIDE DIAMETER, for those who have no clue what the acronym stands for) is *60mm*.

A 2.0" hose will stretch to accomodate the slightly larger 60mm.
BTW, 2.0" = ~52mm (multiply by 2.54), so we're talking about a 8mm difference in diameter.
Flexibile rubber / silicone will stretch, but this is not recommended.

Not recommended?
Why?
That particular application has heat and vibration.
Using too-small of a hose will prematurely cause it to crack and fail, especially in the case with non-reinforced rubber.

2.5" is a better compromise - just tight the clamp down to the smaller 60mm O.D. of the turbo inlet.
2.5" = ~65mm, so we're talking ~5mm oversized.

Is the name calling really necessary here???
