M923 NHC250 Turbo Prodject[/h]

Bought a running 1978 White Tractor with a cummings small cam 350. Removed everything necessary to convert.
Turbo, manifolds, intercooler, injection pump, etc.

Beautiful 931 by the way!

You might get the CPL# off the donor motor to have for future needs & also get some rebuilt injectors for that CPL for correct fuel ratio for your 923.

You can't gold plate a turd. (well, you can but then you just have an expensive turd)
I'm kidding but don't be surprised at the results (or lack there of).

This modification will get you about 20 hp. That is what Cummins rated it at!

you can get more than that you just have to turn the pump up if you are going to use the stock one but if you use the 350 pump you should have close to that when you are done.

Hello
I am wanting to do the same to my '86 M931 and I would like to see the after project complete pictures. Did you install the oil cooler as well from the white? asking because I see the front end of the water manifold. How well did the after cooler fit?

Thanks

What about piston coolers? These engines didnt come with them since they weren't turbocharged. That's what I have always been told.

Correct, they lack the piston squirters.

That said, I own and have owned several engines that were NA engines I added a turbo to. As long as one does the install without expecting to turn the fuel WAY up, they can live without them. (But I recommend gauges and keeping EGTs low.)

Is it worth adding the turbo if you can't turn the fuel up that much?

wrenchturner6238 · Nov 13, 2013

Yes i believe it is and will be when i am done. 20 or more HP will make drive ability better for hills and loads if you have a load to haul.

It is worth it in my opinion. My 250 runs ALOT stronger.
