So, for those not bored with these posts yet, I spent a bunch of time crawling through the “modified” section of the low HP tractor forums, as well as some diesel forums and the out look is good! Most seem to agree that these small, understressed diesels are *WAY*, *WAAAAAAY* understressed in order to provide bulletproof reliability even if you defer maintenance for years at a time. in short, here’s the basic steps to installing a turbo on a 1.5l 3cyl 28HP compact utility tractor diesel:

1) obtain a turbo (it has been suggested the unit from a 2.0T Saab is a good fit, and the waste gate is already set at 8PSI)

2) make sure you won’t make more than 10PSI boost (or install lower compression/forged pistons in which case go to 5)

3) fab an intake pipe, exhaust flange, and oil supply/drail line by whatever low-leak methods available on shoestring budget.

4) install turbo, gain 2-3HP.

4a) stick a high temperature probe in the exhaust flow, load the engine, and crank up the pressure screw in the injector block.

4b) If the EGT gets over 1100 degrees, or it starts to smoke, back it off a little bit.

4c) enjoy 50% more power (+~14HP = 42)!

optional:

5) install boost-regulated variable fuel pressure regulator, intercooler, water/methanol injection, maybe think about piston squirters too... Enter the local tractor pulls in the <3000lb class, kick ass, replace clutch, repeat.

6) Profit!

14 hp? Just get a k&n filter and call it a day.

Why use a fancy turbocharger when you can just use a leaf blower?

dude, 14HP is 50% of stock, it may not be “much” but it’s a signifficant improvement!

Better be careful running the implements if you are making a lot of extra horses. Twisting up the PTO won't be appreciated.

because the turbo sounds better.

well, our big concern is we want to use this to make hay, and the 1720 is right on the borderline HP-wise to run a haybine or baler, the turbo would put it into comfortable-margin territory, while still being way under the max the implements can take.

But k&n promises hp gains of at least 14hp! More with additional stickers
