Im getting ready to install my T04X^2 setup but my HKS cast manifold did not come with hardware. Im assuming most opt for studs rather than bolts for the turbo to manifold connection. Im wondering if a grade 10.9 steel stud would be fine or if inconel is required. I know the grade is a measurement of tensile strength and has nothing to do with heat capacity/resistance to thermal expansion, but will it suffice?

Thanks all

10.9 would be fine. The trick is how to keep the nuts tight.

I was thinking washer + lock washer?

Lock washers lose their temper at the temps turbos run. Look for Copper lock nuts, specifically designed spring washers, or some type of safety wire retention.

i'll be using copper lock nuts with these Nord-Lock | Wedge-locking washers and Superbolt tensioners | Your trusted partner for optimizing bolted joints
