Some more routing. Nice and tight and high. Have I mentioned my buddy rocks!

Rear Routing of the exhaust. The Aerotubine tucked up nice and high and not below the frame.

Quick and dirty paint job on the bung. Got this brazed nicely for the very low cost of free. Don't mind the red paint. It will be touched with some POR-15 soon.

Myself cleaning the mating surface to put the oil pan back on.
Its an easy job on the whole just s***ty dirty work.:meh:

Braided Lines for the oil and water.
These are a little tricky to get set up but are quite nice.
I like them, we will see how they hold up.

4an lines for the oil feed and water. (silver for oil and black for water lines)
8an lines for oil return back into the pan.

I'll take a picture of my oil feed. I managed to utilize a system that I could still have a functional factory gauge and a isspro sender all in one location. This was a bit tricky.

Water lines.
I bought nice clamps and I am really glad I did. Breeze clamps I believe.
5/8 fittings fit a little loose but we will see how they hold up. They tightened up just fine.

Routing them.

Used a 1hd-t airbox lid and crossover pipe.

3" hump hose coupling from the lid.
5" of 3" stainless
2 and 3/4" to 3" 90 degree bend from the turbo inlet.

A bit tricky to fit. Might look into a 1hd-t airbox hose.
Also the airbox clamp is directly in the way and takes some prying to get it seated nice.
This could pose a little bit of a pain in the ass. I might relocated the little clamp at some point if it bothers me or give me huge trouble.

Thanks Adam for the crosspipe. This made things a ton easier. :cheers:

great work! when the snow melts and the weather stabilizes a bit (no shop that I can drive into) I might be asking you a lot of questions as thats when I'll be doing mine. keep up the good work

Very Very Nice :cool:

Thanks for the detailed explanations and pics!!
You mentioned "brazing" the bung fitting in the oil pan - was that to minimize heat and warp of the pan?

That would be the best educated guess.
 
Wednesday morning my exhaust will get tig'd
I'll wire some gauges tonight.
 
Although I love my 80 Series, I've always had a soft spot for the 70.

Awesome build!
 
Exhaust got tig'd together today. Time consuming and expensive little process but I do appreciate nice work.

Tomorrow I have to:
Zipcut one little thing off to mate a flange,
Put it the exhaust back on my truck
Split loom some gauge wiring under the hood (have i mentioned I HATE wiring)
Tap into the illumination feed for the gauges
Drive it for a baseline
Turn up the fuel screw and tune it:cheers:

I'm all smiles well for the most part now, I haven't even touched the fuel screw.

When i took the exhaust off to get tig'd i had two hangers break. I too note of their location and told the welder to proceed. The two were right out after and made the install harder than normal. Too hard to be honest. A torch fixed that and bent them up a bit. All installed.

Didn't get the gauges in for the initial drive. Sounds nice, drives nice and I haven't even touched the fuel screw. I am all smiles, sounds great and definitely has some more pep, smooth power delivery for sure.

Glad I went with the big aeroturbine as opposed to the little one. The 3030XL does have some ceramic baffling in the entrance which I am sure helps quiet it a little bit. It does sound sportier than normal and you can hear the turbo noise inside the cab with a small increase in noise. I don't think its bad at all.
My buddy who did the exhaust and install with me says its what a diesel should sound like, the turbo noise but not a nasty rattly diesel where you can't hear yourself think in the cab. That nasty diesel loud like a powerstroke is what I am talking about when your in the cab an its still freaking loud. I had a friend tromp on while I listened outside on a few drive bys. It won't wake up the neighbors, family or the girlfriend, sweet. Turbo sound can be heard as soon as the truck passes and the truck is pretty quiet from even a distance. I'm happy with the exhaust at this point.

Just wired up the gauges. Pyro won't work just reads 0. The illumiation works just fine. Triple checked my wiring as the other gauges work. I also tried programming this gauge in the past to have a warning light come on, I contacted them to see if I clicked a wrong parameter to make the gauge not work on the programming. I'll play with this tomorrow and I will hopefully hear back in the morning.

Anyone using the EV2s in a 24v truck you can connect the illumination directly to the 24v source, they said it would be just fine. I am not sure about hooking up the gauge itself to 24v though, you will have to ask them.

Did a test drive, I like the gauges, brightness is fine. Got the boost gauge up to 15psi, holy s*** :eek:(walking on it getting onto the highway).
I think this might have to do with a tight boost line from the compressor housing leading to the wastegate actuator (was kinda bent weird when I installed the silicone, figured this might be an issue). Threw Graeme an email for his thoughts.

I ordered vac line on the 23rd and I am hoping that will be a fix as the actuator has 10 psi written on it.:meh:
 
Nice build, and I'm particularly impressed with how tidy the turbo install is.

When you're down to the coast be sure to drop me a line and swing by to say hi!

This spring I'll be down for a little trip.
I'll pop into say hi for sure. I might need some goodies.
