Btw great job so far and I appreciate you taking pics of everything

Thanks, Trevor. Pretty sure mine is welded tubing, though it does look cast in the pics.

I was hefting the turbo tonight and it's quite a heavy beast. The manifold, as you know has 2 studs/nuts up top and 3 below. I don't quite understand this as the reverse would be more structurally sound, IMO. I'm going to see how difficult it might be to adapt the existing manifold support bracket to work with the turbo. There are 6 bolts on the compressor housing and 4 on the turbine. If it works in a way that the turbo downpipe clears the stock support bracket, I may see if I can bolt a support arm from the stock bracket to the turbo using either the compressor or turbine bolts - which ever is more centered over the support. I know the turbokits guys knew what they were doing when they built the kit, but it just seems like a lot of mass hanging from that manifold. The manifold itself could probably hold a ton (not exaggerating) but I'm a concerned about the 5 fairly small studs/nuts that hold it on. If the Toyota engineers thought that the small lightweight manifold needed a support, then I'm thinking that this turbo is a heck of a lot heavier and could use some support. Maybe I'm overthinking this.
