Add turbo

[Oil pan 4]

I ran the adiabatic compression calculation and it looks like if the turbo was 100% efficient, which its not at 6psi of boost my intake air temperature would be 144F if I stated with 80F air.
So if I'm only running 70% efficiency it could be more like 160F.
Even at 4psi I would be looking at 125F if the compressor was 100% efficient.
So an intercooler is probably not a horrible idea.

I wouldn't use any efficiency higher than 70% even if the manufacture claims higher. Just my take on the real world and it's nice to have margin.
Yes, I would use a cooler, any is better than none unless it is a (large) restriction.

Peak efficiency on the rhb31 is 68%, but I will be using it around 55% to 65% efficiency areas of the map.
So it could be pretty warm.

The Toyota mr2 intercooler seems like a decent choice. Definitely get one with 2.25 inch pipes.

I had forgotten how inefficient these small turbos are. The TB02 (dates me) was the only small turbo I have owned and played with. Pulling from some brain cells I tried many times to kill: I think it was 55% at 18psi on a 2.2l IDI.

Sooo, whatever happened with this?

Also interested in an update.

Took the turbo stuff used the tractor like normal, but now it's going back on.
I made a battery and intercooler bracket out of 304 stainless.
I ordered all the couplers I think I should need from frozenboost dot com because they usually ship next day and I'm so close to them I get it in a about 1 day.
The battery box was all rotted away so I took it apart with my plasma cutter and built it back with 304 stainless steel 1.5 inch 1/8 thick angle. And some flat bar to hold the intercooler.
Intercooler is going in horizontal.

A guy here added a turbo to a L2501. He cheated though. He works on diesels all of the time. I’m sure he probably could sell a kit to the L2501 owners if he bothered to put it together. Apparently, he’s too busy to put it together.

I’m not really sure if it is “legal” or not.

What’s illegal about it?

Clean installation on a clean tractor! Nice job!

Not illegal just cheating because he’s an expert.

I had to put my air filter up high because of all the dust here, oh and the intercooler is where the air filter is supposed to be.

I got the intercooler to engine pipe done it was easy. I'm going to go with tig welded 1.5 inch 0.062'' wall 304 stainless for most of the intercooler pipes.
I will be chopping the hood, but my hood is held together with rust and bondo so no big loss there.
Need to update with pics.

I'm 1 flexible elbow, 1 cut and 1 weld away from being able to fire it up.
We'll the oil doesn't have a return yet, I will probably just jam a line in the dipstick hole.
As soon as that elbow comes in I can make that last fitment adjustment, welder up and the turbo pipes will be all done. The intercooler needs a fan too but that doesn't have to be done immediately.

I fired it up with a container under the oil return, it gets good oil flow a little too good, I may need to choke it down a bit.

The kubota makes around 50 psi of oil pressure cold, it runs about a half quart of oil per minute.
I tried some blade work with the now turbo charged kubota, the turbo barely kicked in.
This weekend I'll put the brush shredder on and that will test it.

I put the brush hog on the turbota and it was running good, real good. But the first time I got on the boost the exhaust manifold gasket let loose after several minutes. It was pretty much just rust.
I bought a new gasket a couple of years ago but seem to have misplaced it. It has plenty of power and doesn't roll coal hardly at all.
