Default 2JZ mani stud question

Hey guys,

I only ask you guys because I trust this community will know best of all of the communities I am involved with.

I have an RZ here destined for 1000whp and At this stage I just have to bolt it together for the guy and fab his IC and intake pipework.

Long story short the only real question I have is regarding the manifold to turbo studs.

Neither the manifold(ebay, repaired eleventy times) nor the turbo(GTX42r) have threads, both are drilled at 11mm (approx).

I have metal gaskets supplied. This is intended to run at 800whp on this first setup for a few passes until the manifold fails again and then along with a full motor build a new manifold will be made for it.

So the question is basically, with a turbo this big and heavy do I just use 10x1.5mm grade 12.9 Bolts or do I tap the manifold and run inconel... or what?

Thanks heaps, sorry its not a miata, here are some pics
