Does anyone know the size and thread count on the studs that come welded to the truck manifolds? I dont want to have to take them off and bring them to the hardware store.

Also, what hardware are you guys using to mount your T4 turbos to their flanges?

The studs on the manifolds come out. They shouldn't be welded I don't think.
As far as hardware, I just used some grade 8 bolts and nuts to mount the turbo to the flange.

I meant configuration and size. For instance, my T4 flange on the merge is threaded. I got some M12 bolts to match up with the threads. When I looked at the flange on the turbo, there is no way to get a long M12 into the hole due the exhuast housing being in the way. This makes me think that perhaps I should tap the back bolt holes and stud them on the turbo. Then have the hot-side flange have the other 2 studs. Get the back 2 from the top and the front 2 from the bottom. sound good?

10X1.5 or 3/8-16 work too very similar threads **
