Here's Art's input on the turbo:

So they did supply a flange, but it's a non separated flange. AFAIK
no one makes a separated/divorced flange for this turbo, so the only DP I can make with the supplied flange will be a single exhaust pipe like this:
Also, the flange is a 1/2" solid cast piece. There is no cavity on the back side, so the WG flapper will be limited to just a few degrees of range. About this far open:
This along with a smaller than Garrett WG hole, I think, will lead to boost creep.
So what do you think? Do you still want to use this turbo?
I don't want to clutter the OP's FS thread too much, but some clarification was needed on the dp flange.
The included flange looks like it could be easily modified for a seperated gas dp. and with a little porting the wastegate could be improved and this would be a great churbo option. I still love that wastegate mounting solution.
