So you have you driven a car with a GTX3071 and Tial 1.06?
I didn't have a choice as Tial are out of stock of the .82 and .63 worldwide and the other flange types just wont fit where I have mounted it. Like I have said, this housing will be perfect for the 3.5L I am building. I am hoping it frees up the top end and gives me a more gradual boost curve, I didn't like the way my highflow snapped on at 3k anyway.
GT35's aren't my favourite turbo, I have heard of too many failing, even at low (less than 20psi) boost, perhaps because they are so common?
