a t3 flange, why?
i would def. think that you would want a t4 flange for a single turbo? what size is the hot side, i bet it spools uber fast.
most people run t4 turbos, for single setup, if that is what you are referring too

I also had a MPT 70, it was a T4 flange.... .96a/r
Why are you using 3.0 tubing for a crossover? 2.5 is plenty.

There is a decent merge in this post, I prefer to cut the tubing a bit tighter on both sides and slip it into the flange. Then I hammer form it with heat, vise and a hammer....also a nice block of wood helps form the corners just right. Fit it to the flange and finish weld it.

2.5" crossovers will support a LOT of power, I had the same idea to use 3" for a crosover but changed my mind when guys with single digit 1/4 mile cars told me they were running 2.5"
Here's a pic of mine, I used the food color trick to get the angle right.
Its a T4 flange though.

Its a very handy trick to know, I've used it more than once building stuff for other people. Its also a really good way to make a turndown tip out of a 90 or 45*
