it's to verify if dia is larger than prevoius series avoiding to buy larger aftermarket chamber not so cheaper like OEM. Why to pay $900 for Cusco Throttle if OEM US may cost half?

I'll save you time, money and effort.
A larger throttle body isn't going to do anything on these cars. New version or old.

Still make zero difference.
The throttle body is not a restriction at power levels under 800+ hp.

It is larger 70-74mm, something like that. Zero guarantee it will fit GEN1 IM as the bolt pattern may have changed. In the states I sent my OEM TB to Maxbore.com to enlarge from 65 to 68mm for ~$150. Maybe he'll do international? This is all Cusco does. It makes a noticeable difference in midrange and drive ability when NA because not everything is about peak power.. But with FI since you aren't trying to vacuum air in as it is forced, a larger TB can become more on/off switch when it comes to throttle modulation. I still have my bored out TB with a JRSC and I'd skip it tbh.

Related question: What can I use instead of the $35 throttle body o-ring style gasket from Subaru?
What is its size in mm's? What is comparable?
Surely the 71mm throttle body is a standard one used on many cars as the style of gasket is everywhere for $5, but I don't know which one fits!
Subaru Part number: 16175AA570
The dimensions of the groove it fits in are: 82mm OD, 76mm ID.
In cross-section it's like an airship/fat cigar shape and that end to end dimension is around 6mm.
It's not like previous Gens where it was a flat gasket like most older Subaru's run.

i was always told cereal boxes make great gaskets...

knew a few guys that would have perpetual diff leaks using the oem diff cover seals, but make one out of a cardboard cereal box, and it'd never leak again
