If you want peace of mind, you could have a support welded from the turbo flange to a place that bolts to the head. Really not necessary, though.

Lastly, 10.9 bolts are way overkill. 8.8 bolts would do just fine and even that's stronger than necessary.
Thanks! I'll take the parts to the store to see what threads and type of head on the bolt will make installation easier if i have to do it while on the car.

Ill see how it all is after installation but yea, i shouldnt need supports. Most people dont have any.

Next, should i slot any of the holes on the flange of the manifold? I was told I should to avoid cracking due to expansion while heating...

Lastly, should I wrap the manifold, even thought it's small, or just leave it be until i ceramic coat it?
