a couple small changes on the ebay hotside and it works just fine. New v bands from precision, maybe a cut and re weld or 2, and wrap it, and its pretty nice for 500. Its not really a easy bolt on kit though...but then again, its 500. I've got a on3 ball bearing 76 on a ebay hotside with a/c..its not bad
IIRC the TC76 is a 3" v-band outlet and the TC78 is 3.5" right? I mean I have a TC76 at home I can just check after work. I'd rather use the on3 in my build than the TC76, but my kit is already built so I need to figure out if this will go in it's place directly.

I'm pretty sure the on3 76mm is a copy of the TC76. All the dimensions match the TC76 for wheel size, etc.
Just FYI for everyone - this turbo is just a rebranded generic T76 turbo. If you google 'T76 T4-68-2' you'll find all the wholesalers. it's still cheaper to buy from on3 if you buy a single though..
T76 T4-68-2 = .68 a/r
T76 T4-81-2 = .81 a/r
T76 T4-96-2 = .96 a/r
T76 T4-68-2 = .68 a/r
T76 T4-81-2 = .81 a/r
T76 T4-96-2 = .96 a/r

It is the same dimensions as the generic turbo, but the quality seems better than other chinese turbos I've seen. Also, I haven't come across a generic turbo with a ball bearing center section yet.
I'm definitely going to pick up an on3 76mm for a beater project!

I'd be willing to bet the on3 turbos are made in the same factory as the Magnums. Especially considering they have ball bearing models as well.
Or they just buy all the pieces from the same factory in China and assemble them in Brazil 
The have said that they use "common components" before. Now they are releasing an 80mm turbo right about the same time they are showing up on several chinese websites for turbo manufacturers.
