Turbocharging new L3940 Gutless Pig Tractor

Instead of bashing my new powerless L3940 HST Cab tractor I would like to turbo the thing. I see the same engine is used in the Bobcat S-160 skid steer with a turbo. Rather than tell me why I don't want to do this can you throw me some ideas? Very serious here. Thanks, Fred

I Still Hate My Tractor II

So I have 50 hours blowing snow with it and now running an 8 inch Woodmax chipper. Before the turbo install the tractor engine would die out on anything over 5 inches of wood diameter. Now with the turbo you can't kill the engine, in fact Saturday I got a large piece of Maple stuck in the...

I have been posting here since 2011. I cannot recall ONE thread where adding a turbo to an engine not specifically set up for a turbo proved successful for the owner.

No wonder, five foot is too big for 25 hp. I bet it bounces off the tires when you take a sharp turn. Sell it and get a four-foot mower.

Umm, I ran a 6' behind a 2501. Type of stuff that is being mowed dictates speed of mowing. Bogs down, slow up. Its that simple.

Well, this is orange, and it's turbocharged. Seems to give it more power (if not sense)!

Not what I’m going for, although, it’s highly entertaining!

hello TBN people,
i would like to share some info on the D1703 engine used in the l2501
L2501 Modifications .
the OP that started the "L2501 Modification" thread has successfully built and installed a turbo for his D1703... also a small group of us over at OTT have done the injection timing and fuel advance mods on the D1703 with great success.
we have some very knowledgeable members (gearheads) involved in this thread including @Rdrcr who is currently installing a turbo to his D1703. Mike has been a big contributor and help to the thread!
here is part 1 video and history of the D1703 mod

part 2

i have no idea how much HP and torque i gained on my D1703... but its not the same tractor

When I was looking at the 2501 awhile ago, my plan was to put the inj. pump to L3200 settings and changing out the pto gear so I could turn up the rpm to gain more power and increase the hyd pump output also.

I like turbos but to make it right really requires different pistons, injectors, inj. lines etc.

Nope, does not bounce off the tires.

A predictable result!

I watched both of these videos and found them to be long, detailed and very informative. He gained some hp (doesn't know how much without a dyno) and did not add a turbo, which I like. The guy has done his homework and really impressed me with his skills and knowledge. If I were younger I might attempt his "tune up" but at my age I don't think I'm capable. Wish I was!

yes sir, the videos were definitely long! outta respect for Netmagi, i watched both from beginning to end.
very informative and Kubota's D1703 is a popular engine for sure. interesting that the engine has been used in the l35 backhoe (35.1 HP), l3400 (34.7 HP) and l2501 (24.8 HP) to name a few. if i had to guess (butt dyno), i'm thinking ~32 HP after mod.
the mod took ~4 hrs plus 2 hrs collecting data, tweaking fuel limit screw and checking EGT's.
gotta say i had a good time working on my tractor... its 100% solid now!

best of luck!
