Default TID strange size inlet on turbo, any reccomendations?

I need a new TID, I can get a 2.5 to 3" couple no problem and i have the 2.5" aluminum piping, but i cant find anything local to adapt the 2.5" to the turbo inlet, any advice for me? Anyone stretched 2.25" on there by any chance? I might be able to get that, or perhaps some hardware store might have something i can use, i'm trying to make autocross the 17th.

I've stretched 2" couplings onto 2.5" no problem, and even 2.5" on to 3".

Which makes perfect sense. They are sacrificing safety either way. lol

The stock turbo inlet size is 60mm.
It's slightly smaller than 2.5".
2.5" = ~63mm

I actually have a bunch of red couplers that are 60mm inlet but 2.75" outlet.
I stretch the 2.75" side to slip onto 3.0" O.D. pipe.

I got some heavy duty 4 ply couplers to to stretch from 2.25 to just under 2.5". A little heat goes along way. As does the wholesale size tub of KY I keep handy at all times
