It won't take much clearance. There won't be any movement after it's all installed in the truck.

Yes, I have gotten everything to clear properly now.
It will indeed be very solid once it’s installed. Shouldn’t have to worry about leaks at all.
Even though most of the hardware in this mock up iteration is new, it’s not what will be in the final install. Class 10.9 and grade 8 CAT bolts will be used.
Also need to get a new crossover pipe, the old one is cracked.
I wish I’d done a mock up with an E4OD, I could still do that yet tonight. The transmission dipstick tube is yet to be resolved. Cab clearance likewise. Since the cab and engine are yet to be removed from the 94, I can’t attend to that at this time. The engine is getting upgraded valve springs, factory turbo head gaskets, new IP, new injectors, deep cleaning and head studs at a later date.
I think I have the cold side housing where I want it, but it can be changed if necessary. Wastegate will obviously be adjusted far in the future, during early stage road tests.
The quality of these pieces is terrific. Props to IDIoit and R&D. Amazing work. We are all fortunate to have them, their knowledge, and their skills among us. Wonderful community this is.
I do have a couple of questions for Justin at R&D that I’ll call him about tomorrow, the downpipe seems short before it angles back toward the rear of the truck. But with no cab, it’s hard to tell. I would’ve thought it wouldn’t make that change until about midway down the frame rail.

The cold side housing is another thing. There are some tapped holes that aren’t plugged that confuse me. I think one might be for turbine speed, but that’s just speculation. I don’t actually know. It could be for boost, I don’t know where it leads.
I’m not convinced the other hole is a port, it might just be for mounting something. I’m sure Justin will know.
The turbo drain pedestal supposedly needs clearancing, according to R&D’s website and the included information pamphlet. I didn’t have to clearance it, there was plenty of space between it and the cold side housing mounting bolts. Being non intercooled may change that need, what with likely tighter tolerances, as there is quite a bit of play in the mounting holes of the pedestal. The turbo’s design allows it to be used as a drop in upgrade, which is a tall order compared to the relative sloppiness of intercooler piping.
I need to order an 093 install kit, with new O rings, gaskets and seals.
I’m excited for this project to come together. Should make some significant progress this fall and winter, with enough input this summer to keep it slowly moving along.
This summer may lead to a different nature of automotive project, that will likely be executed in a similar manner as my 91, smaller upgrades along the way, while using it.
