Turbo on the 2-71?

Hey, here's a crazy idea.  Would it be possible to put a small turbocharger on the 2-71 in my HD5G, in addition to the supercharger?  Seen some crazy stuff being done on other diesels and this came to mind.  Anyone seen anything like this?  Any other ideas out there for boosting the hp a bit, without swapping motors?  What do you guys think?

Tag on the 2-71 in a HD5 says 48 HP from the one i have at least. As i used a later style T piston and liner in mine and upped the RPM some on governor I figure it's around 55 HP. As Detroit on their Silver Series used both Turbo and Super charger it should be possible, and that thought has also crossed my mind.

If I'm not mistaken the compression ratio of the Detroit motors are different when comparing turbo charged versus naturally aspirated engines. I know it matters on the larger cubic inch detroits, better check with the dealer to make sure you get ALL the parts that need to be swapped out to make sure it works right.

When the Detroits were Turbo'ed from the factory, the blower drive ratio was changed to run it slower.  That way the blower did a little less work, the turbo made up for it as needed.  The efficiency was better that way.

Okay, so basically I should be looking for a turbo similar to that on an AC-200-7000-7010; replace the injectors w/ units built to handle the greater air volume; and possibly look at turning down the blower.  All will require a bit more research, I think, but I am definetely going to try this.  I have a spare 2-71, just in case...!! 

If you don't decompress the engine(shorter pistons) the compression ratio change will crack the head or cook the pistons leading to failure either way.  We had 318 Detroits 8V71 series with turbos in trucks, these engines when supercharged with a turbo became 350 Detroits but they had extra fuel delivered, decompressed pistons, different blower drive gear sets as well different lobe design to the blower, different sleeves and yes the inlet ports were different, and the cam timing was different.  Just adding a turbo may cost more than you can imagine once the damage starts.

The 350 Detroit smoked like hell cold and at a idle after sitting for a short time, very evident which ones they were in a lot while running.

Dont do it! The reason hd5 cats lasted so long is that they were underpowered. Hd6s didnt last nearly as long as it was basically the same cat with much more power. If you want something that can do more work, find a hd11, they were good cats too, TREV.

Have been seeing on other sites were the 2-71 has been replaced with a 3-71.I think this was in a farming tractors rather than a dozier.Have a cousin that farms with HD9's,he has put 4 valve heads and larger injectors in 2 or 3 of them.Lots of power but now has trouble with final drives on a regular basis.I would think  using larger injectors and pistons and sleeves for the higher horse power would not put an undo strain on the rest of the drive train,if you us a little common sense.  

Many HD5s with 371, 371N, HD9 and dry clutch HD11 with 471N and 671, and HD16 with engine power boosted way up over HD21 spec down here. Final drive failures would only occur with the same guys who wrecked final drives on factory horsepower tractors by not keeping bearing preload up on all shafts, or putting severe impact on them bulldozing and ripping in rock. I was one of the `wreckers` when I started. Now that I know how to look after final drives and other tractor componentry, I dont have any trouble.   Mac
