I came home to some boxes today too..
See my build thread for part info. I bought it through amazon
Builds - Spyduh's LX450 Build (Motor Rebuild + Wits End Turbo Kit)
My beater has a weight issue. Taking it to my buddies shop for some quick work then back home to do Transgo and install the lowrange tcase

I am using DEI velcro closure heat shroud. They make three sizes. The large size I put on the large AC line on the P side fender well. The medium size I used a portion of it on the harness at the EGR pipe on the back D side (I was in there, might as well). The smaller size I put on the AC line on the firewall, P side.
Heat Shroud™
Heat Shroud is a high temperature rated line sleeve with a hook & loop closure design for easy installation to provide heat protection your wires, cables and hoses.

I used everything outlined in the @spyduh build thread.
My wallet hates him right now. I literally have a box of parts waiting to be installed that have all come from his build thread.
I see these different materials that people use and I wonder the effectiveness of them. How good will they be at protecting the wires after an hour? Will they get heat soaked and allow the wires to heat up? I looked up the different sleeves and didn’t find much data on them on the supplier’s web pages so I decided to dig a little deeper. I guess wire bundle materials interest me.
It looks like SAE J2302 is the standard used for determining the thermal effectiveness of tapes and sleeving. I found a report on performance testing of automobile wire harnesses that provided some good information.
I’m not suggesting the materials referenced in this thread will be ineffective, just that there really isn’t any data to support how effective they are in normal use. The material suppliers may be able to provide additional test data. If I were looking for material I would look for something that was tested to SAE J2302 because I would know what I was getting. Of course cost and availability may be issues with these materials.
Links to the performance testing report and a couple random SAE J2302 materials I found.

Summit and Jegs both have a full selection of heat shielding for every application. There's a lot of cheap knockoff heat shielding out there so go with a reputable brand or you might get some expensive Chinese tin foil!
I buy a lot of stuff from WireCare. They have a decent selection of high temp stuff.
So my turbo is here and next up is finding the time to start on it. Quick question though about the turbo itself. I assume it’s fine or Borg wouldn’t have sent it out but this seems like an awful lot of material having been shaved off to get the fan balanced. Thoughts?

That is fine, won't hurt a thing.
Thanks!
I might post another pic when I get home just to show how deep those two purple cuts are. This pic doesn’t do them justice.

That is not a bolt head or anything, it is simply a pad to balance the shaft. The turbine and the shaft are all one piece.
Ah, okay. So it’s not really structural or anything. Very good to know, thanks again!

Nope not structural at all, it is there to grind off and balance the assembly. The only reason it looks like a fastener is so you can hold it steady while you tighten the nut on the other side of the shaft that holds on the compressor wheel.
Its awesome to see MUD'ers getting their turbos and starting the install, but what batch is up next for the others that are still waiting?
I did my Mechanical Engineering internship at Garrett (Allied Signal at the time) back in the early 90's. Part of my job was to verify balance on all of the turbine/shaft assemblies for the prototype units prior to assembly and then balancing of the rotating assembly after assembly. The drive feature on the hub is used to hold the turbine/shaft assembly during several stages of the manufacturing process. After that, it is just sacrificial material for balancing the rotating assembly. They get cut on twice, once for the turbine shaft assembly balancing, and then again for the rotating assembly in the center housing with the bearings and compressor wheel. I saw some with far more material taken off than that. Not an issue.
As a side note, I have run this kit by some of my former interns who work for Garrett/Honeywell. They are very impressed by the quality of this kit, the engineering that went into it, and how complete it is. From an ME designer standpoint, I love the attention to detail and thought that has gone into every aspect of this kit. Joey has done an incredible job designing this kit.

@spyduh just contacted me with an oil leak issues he’s having with the oil pressure line in the turbo. Turns out his hose has a failed crimp at the turbo end so oil drips out into the heat sleaving.
If you haven’t already noticed an oil leak issue you likely won’t but it’s good to know where the potential is. I carry plenty of extras of all components of the turbo kit for just these scenarios. A new hose is going out to him today. He should post up what he found.
I’d rather all folks are aware of any potential for component failure instead of hiding it.
