Are these Seq or Non-Seq?
 
3 Attachment(s)
I bought these thinking that they were non seq, but from what I was reading and
what I'm seeing they look seq. Can some turbo heads holla @ me? maybe I'm lookin for the wrong things.

I've tried to post the images hopefully they show up..

Everything highlighted in purple is what I was looking to be welded, these parts
aren't moveable by hand, but still look like they will move under normal operation.

Is the crack highlighted in green render the housing useless... it passes light.

Thanks in advance

Those are Seq. I wouldn't port that wastgate, that crack looks to big

Don't know about the non vs seq for sure, but they look seq to me. I wouldn't use those for seq, that cracking is fairly bad. Also, that one crack out to near the gasket is fairly bad too. They'll probably be OK for non-seq use, but I hope you didn't pay a whole lot for those.

It looks sequential to -- the turbo pre-control wastegate is still there.

Sequential. Here's the rundown on what's in the pics:

1st pic:
- top left is wastegate lever arm
- bottom right is turbo precontrol door

2nd pic:
- stuff (3 highlights) on left is the wastegate
- door on right is pre-control

3rd pic:
- all pre-control, with cracks

The wastegate looks pretty good. I don't even see any cracks, though I would expect that you would see some if you open the flapper door. My wastegate was cracked all the way through the metal to the turbine outlet. :) That wastegate should be fine.

Don't port the pre-control even if it didn't have cracks. Those cracks are pretty big, but not all that unusual. The turbos will still work but you might have lower than expected primary boost.
