Default FAST intake size question ?

I just want to be 100% sure on this, the only difference from the 78mm vs. the 90mm intake is the TB size right ?

no, in fact the throttle body isnt included in the price of the intake
78mm = $7xx and 90mm = $8xx. The TBs are like $400-500 extra.

The only differenc i think is the upper part, which is swappable, like if you get a 78mm and want to upgrade later you can buy the top part to convert to 90mm. I'm pretty sure thats what it is.

Depends on to what differences you are refering.

The runners are higher than the LS6 so your FRC'S won't fit right afterwards. They can be "adjusted" to fit but it won't be very pretty.

All the hardware, holes, bolts, etc. is the same and supplied in the FAST kit.

Yes it's pricey . . . but worth it if you've got the money and making at least 450rwhp already . . . otherwise I don't think it would be worth the price until one has the accompanying mods to make that power

The opening on the front of the 90mm intake is a lot larger than the 78mm. You then must buy the TB separate depending on the intake you purchased. Not really sure what your exact question was refering to but. Hope this helps.
