Turbo NH 1620

[Whitbread]

After the last snowstorm, it was very apparent my 1620 could use some more *** for blowing large drifts. For a total of $300, it's now turbocharged!

Disclaimer, diesel performance is what I do for a living. I fully understand the potential risks and methods for minimizing them.

Please don't judge the charge pipe, I needed something quick and easy as this whole job was done in under 7 hours. I'll eventually build a nice pipe out of 1" ss tubing and use a proper reducer to step up to intake manifold size. I'll post more pics tomorrow.

Nice. How much more power did you get?

Interesting. :thumbsup:

Once the fuel was turned up I bet he had plenty more.

Nice to see someone else turbo their FORD.
I installed a turbo on my 1720 in 2011 with excellent results.
I’ve use the extra hp often but it is most appreciated during the winter.
The additional hp lets me clear my driveway much quicker and I like that when the temperature is in the single digits.

Finally got a chance today to mount a temporary boost gauge, tweak the fuel screw, and go out and play. Backed the fuel screw out just shy of two turns and HOLY CRAP! This is how it should've been from the factory. I can actually drive up my driveway in high range at full speed. Before, I'd have to drive in medium range or else it would stall out.

Went across the road to the neighbors place for a good test with the blower. His driveway had about 10" of snow on it and is even steeper than mine. Normally I'd have to creep as slow as possible in low range with a full blower width and feather speed as needed to keep it above 2krpm. With the turbo, I went up at full speed in low range and it stayed above 2500rpm.

I have an egt probe on the way to read with the multimeter, but considering the exhaust is cleaner at full load than when it was stock, I know it's not anywhere dangerous.

My only complaint is that I can't hear any whistle :laughing:. Otherwise, I don't know why I waited so long to do it!

Here's some pictures of building along the way:

Cute turbo sourced for $250 from ebay




What we started with


Adapter plate




Fits like a charm


Pulled the banjo bolt that fed the cylinder head with oil, drilled head through, and welded a -4an bung on the end


Welded up a -6an drain flange


Used a sharp punch to pierce the oil pan instead of drilling a hole and making shavings, tig'ed on a 6an male.

Nice work. I've dreamed of doing the same to my JD 3005, (under-)powered by a Yanmar 3 cyl 1.3L diesel motor. Factory rated at 27hp, my fear is the rest of the drivetrain is already near its limits, and while I could gain a few HP at the motor, might overload the gearboxes/pto system. The research I've done shows the trans only used on smaller tractors, none larger. I'll risk it once I've got another tractor in the barn as back up.

If you're not doing anything abusive with the tractor, I wouldnt be that worried about breaking the tractor. Putting an extra few horses through the pto system isn't going to spell instant death. Hit something real hard without a shear point in your pto driveline and you might have issues, just use common sense.

I don't 100% agree with "if you need more power buy a bigger tractor". It's a great theory, but I don't want/can't use a bigger tractor. I love how small and nimble the 1620 is. I couldn't fit anything bigger where I go logging or easily maneuver around blowing snow. The current power level with the turbo added l is perfect and what it could've/should've been from day 1. 28hp just wasn't enough when hills and snow were involved.

Not being abusive... geesh, my poor tractor gets run hard as it can go already, if it had more power, I'd use it... I'm actually impressed how much my lil tractor has taken, considering what I've subjected it to over the past 5 years.

So, as to your 'diesel performance' backround, would you have a suggestion what turbo I might look into for my tractor? Id like to attain peak boost/power at 2800-3000 rpm, out of a 3 cyl 1.3L diesel motor.

Run the same turbo I'm using. It's originally spec'ed out for a yanmar 1.4L 3 cylinder and works just perfectly on my 1.3L. You won't be sorry you added the turbo .
