Yea. I don't know. This is my first experience w turbos. I don't know much, and w the amount of reading I've done I may have misquoted that. Couldn't find the post again.

There are a lot of self taught guys that may not understand an engineers technical description but understand how things work. They use their own terms which might not be accurate but that does not take away the fact they understand how it works and build fantastic engines and stuff.

Came home today to a large pile of parts. Not everything is here but. Everything looks good. Except one thing. The turbo is obviously too big. I hooked up a shop vac to it. Blowing instead of sucking. And with it blowing more than my tractors exhaust ever will. It still didn't spin fast enough.
I will order the other turbo tonight. This one is a .48/.49. New is a .28/.35. The smallest one I could find numbers on. Hopefully this one is small enough. If not. I'm not sure what else I could use.
Pics tomorrow!

Side panel and exhaust off.
Need to get some steel to make flanges with. And some pipe. Then should be good to go.

I'm following this with great interest. This is something I've wanted to do since I bought my tractor.
It turns out there was a turbo version of my tractor's engine that uses a T designator (D1105T).
I haven't been able to find a good equipment list that used it, but I've been able to find most of the generic parts new on EBay.
Is there any rhyme or reason to EGT probe placement? Where do you plumb in for a boost gauge.
If an EGT gauge were used before the turbo was installed would it show a good target temp for the turbo set-up?
Are there any better pics of oil line routing?
I've got a ton of questions if anyone feels like posting more info.

You just need to upload up to 4 pictures at a time via the paper clip at the top of the reply post.
Every time I upload a new photo. The previous one disappears. I tried paperclip and manage attachments w same result. I am on a phone.
So I guess until I can make that work. It will be one pic per post. Sorry
Making flange

Quick test. Confirming suspicion. Turbo on. Full RPM. Not even one psi. In fact. It has a small vacuum on it from the engine pulling in More air that it's pushing.
I don't know why all my pics are sideways... I've never had an issue w pics on forums until this thread got started.

Just a guess but it looks like the turbo is as big as the engine... WAY TO BIG!
Also if your expecting to get any kind of performance out of it using fittings with threads on the inside is going to make that null and void!

That 'adaptor plate' has to be warped.
They do make fittings made to be welded, smooth inside.
Good luck.

If you look back in the thread. I believe even the first post. I mentioned that the turbo would be too big. But was going to go ahead with fitting it before the other comes in. Just to get everything else figured out. Lines. Placement. Etc.Just a guess but it looks like the turbo is as big as the engine... WAY TO BIG!

Why do the threads matter so Much? I've read differing opinions on that. Some saying it only matters in race applications. That the difference is negligible unless the motor is really being worked to its peak. And others saying that it won't work at all.
Curios to hear what your take is.
Why do you think the plate is warped? It sealed fine. No leaks from manifold. Or either flanges.
I searched and searched for smooth fittings. But couldn't find any. Wish I had a pipe bender accessible still. And this would've been a non issue.

In an Intake and exhaust system any distortion in the path, even small distortions, can cause huge losses in proper and efficient flow.
The turbo being too big for the application is significant because the flow is drastically changed in a negative aspect.
In other words both the pipe threads, rough welds and oversized turbo have essentially negated any gains that you could have see.

Normally I would say don't judge the turbo by its physical size; use the specs. However, that is a huge turbo.
Blowing cold air thru a turbo will never make boost. Turbos are not only fans, they work by converting heat energy into mechanical energy. Shop vacs and unloaded diesels do not have enough heat to power a turbo. Any size turbo can be made to work with any size engine if enough heat is provided (or restricted).
If you repeat the test and load the engine to max and then start turning up the fuel you will eventually build boost. It might be way more fuel than you want to use and the exhaust temps might kill your engine.
Please tell me you did not run the turbo without an oil supply as your picture shows.

I buy weld fittings locally, don't know which place has good prices online so here's a google search.
