My other car is a MINI!!!!
Argh! Crazy thread! Stop confusing the poor bloke everybody.
The turbo you bought is the same as the one you have already, sorry dude, you got done. Ko3-026 is a ko3 from a Quattro.
Not all 180's were ko3s, it's a bull**** myth people refuse to let die. Sorry mate.
Now that that's cleared up....
Whoever told you you won't need an fmic with a ko3s: ignore anything they say to you. Ever again
Whoever told you you'll need 225 injectors: ignore anything they say to you. Ever again
Whoever told you to fit an n75J instead of the standard one: yup, you guessed it; ignore anything they say to you. Ever again
If the same person told you all of the above, I'd go one step further and kick his dog to teach him a lesson.
As for Fraggles post above, it's a nice idea, and b5 TIP's are incredible, but sadly of no use to you, as they're ko4 fitment only
And Bobby, try turning your old turbo upside down and you'll see the other side is 3 bolt
