would a similar kit work with 617 turbo diesels?

Nope, we're on our own  ;D

I would say get the engine in tip-top running shape before modifying things.  A guy on the dieselbombers site did this:



I think it's one of the variable vane turbos and the weird linkages run the VVT part.

I think that increasing boost without an intercooler is a waste on gas engines but I'm not sure about diesels. Intercoolers seem to be part of all the benz mods that I've seen so it must be important.

Notice that the pic shows a water intercooler which means a lot fewer ducts.

Wow, that is nice. It's too bad that our W116s have a battery where the W123 owners put their custom air filters. I couldn't find a good place to put a custom air filter on mine, so I decided to stick with the factory air cleaner and service the mounting bracket as needed. The stock air filter breathes plenty well, and you want to make sure that it avoids sucking in hot air from the engine.

I've actually noticed a slight difference in operating temperature, especially on hills, between leaving the plastic intake hose off, and leaving one end attached while letting the other end float to take in cold air from under the hood.

Following your thread made me ask this question', if you were to install an aftermarket turbo for your deisel engine in this case your 617, do you have to change other parts in the engine, like piston rings? I read one parts catalog that the 617 compared to its turbo counterpart has different pistons and rings. With an aftermarket kit, do wehave to change these parts?

The stock Garrett T-3 turbos give plenty of power, and are almost overkill for these engines. You can manually turn up the boost to higher than the engine can handle. If you are talking about adding a turbo to a non-turbo 617, it won't work well, because the turbo 617s have reinforced parts, extra oil squirters, possibly larger pistons, etc. The non-turbo 617 engines can't handle the extra strain of adding a turbocharger unless you run it at very low boost. But then all W116 diesels were made with turbos, anyway.

So for our 116 300SD Turbo Diesels, anybody yet have ...

a. the battery moved to the trunk ...
b. passenger-side high beam light removed & replaced with fresh air vent feeding an aftermarket cold air filter
c. walpro / bosch / _ _ _ fuel pump installed
d. hi-capacity Monark fuel injectors installed
e. Black Smoke Racing injection pump with 7mm lines installed
f. Current generation Garrett T3 turbo with 2.75" - 3" straight pipe exhaust installed

Otherwise inspired by early 1970s Mercedes wunder 617 turbo-diesel C-111 IID with 230+ horsepower ... http://www.eurocarblog.com/post/5533/mercedes-slk-250-cdi-vs-mercedes-c111-ii-d

back in the early 1970s, a Garrett T3 turbo-diesel 617-powered Benz broke too many gasoline & diesel records to mention ... with power (63.33 bhp per liter, bhp/weight 153.23 bhp per ton) & speed (top speed: 186.4 mph and 0 - 60 mph: 4.7 seconds) ...

How many modern, 40 years-newer diesel-powered match that?

Today, with a little lottery money (less than $4k) & elbow grease, eg is there no one who's remade a road-rally version of this iconic 1976 supercar:

$1,000+- the Finns like BlackSmokeRacing.com & Myna Pump can help out on the injection pump

$1,500+- Garrett has the updated turbo

$200 - $300+- Bosch, Walpro, Denso etc have the fuel pump

$500+- Monark has the >1900cc fuel injectors

$500+- for the high performance lines & fittings

... add $1,000 for high performance cyro-brake rotors and ceramic pads and lines
... add $1,000 for heavy duty performance springs and shocks
... add $1,000 for 8x16 wheels and ultra-high performance michelin tires

missing anything?

would be a lot more interesting than the subaru sti i used to own that also struggled to break the 5-second 0-60 mph time ... and never got past 160 mph ... at least that I'll admit to in court ;-)
