found a nice motor in a scrapped loader. says 80hp at 2600rpm.

Turbo charged air cooled 3.11litre.

Anyone know much about these engines?

Can they be "turned up" for more horsepower easily etc? What about RPMS>

Thanks for the info.

Went and checked this little guy out. Really clean. Going to prime it up as its been sitting a long time(3 years) and see if we can get her to fire.

Those are the newer small 4cyl. engines. The turbo is probably the size of your fist bolted directly to the intake and exhaust manifolds. They get poo-pooed a little bit because there is only 1 cylinder head and 1 block. Cylinders/jugs are not replaceable per cylinder like the old 912's. So if something goes wrong it usually takes the whole engine out.

I would love to find one of these for a swap. I dont see why (with guages boost/egt) it couldnt be turned up a bit more to say 90-100hp. With a little bit bigger turbo and a CAC I dont think 120-130 is out of the question.

We modified the rack travel a little bit on one at my old job so it would spin up to 3000/3200 in a stationary pump application for those sticky situations.

Yes they seem really well built and a re-builder i know loves them. Best part is i can get rid of the huge heavy radiator in my m715 and replace it with a big ass intercooler and add more fuel/boost without fear of damage as the charge will most likely be at the same charge temp if not cooler. It looks like a baby t25/t28 turbo?

Yes it seems to be in good shape. Time will tell when I fire it up. Anything I should look for that I wouldn't on a liquid cooled engine etc?

Another question. Does anyone know if these are internally balanced engines? Gotta know for the flywheel etc

That's what I figured too as I see no weights on this one, but thought I'd ask before I fired it over. Trying to see where the best spot to put a mechanical oil pressure gauge would be so I can see what its doing when I run it.
