Cruising through the local Benz eBay ads and came across this one...

Any ideas on what the HP increase would be with this kit?

The safe limit is about 20% power gain because the stock pistons are not oil cooled, etc like the true factory turbo setups. I think their price is steep at $500 when most of these cars aren't worth more than ~$2500... just my $0.02! Interesting kit though.

The description says they have the original receipt from 1976, so I would expect it to be for a W115 240D. And by the way, I bought my whole car for $500. But the head gasket blew this morning, so I won't be attempting a turbo kit any time soon.

Sure would make a nice addon for a manual tranny 240D

How do they increase fuel in the kit? Do they just turn up the max. fuel delivery and leave it at that?

That would be my guess. I don't see an ALDA in that assortment of parts. And I don't think you can swap on an ALDA anyway. This is one of several reasons why adding a turbo to a non-turbo engine has rather poor results. When MB did it "right" from the factory, they got a 50% power gain with no loss in MPG or engine life. Much better to just get a junkyard 617.952 engine and swap it into a 240D if you need more power... or sell the 240 and buy the 300 outright, it's often muuuuch cheaper in the long run....

That's a lot of money to pay for its result. The result will be DRASTICALLY shortened engine life. The 616 was in no way designed for turbo use. If you want a faster car, my advice would be to find a faster car.

Putting this thing on a 240D would be like putting a racing saddle on a pig. If you want a race horse get a race horse don't try to make one out of a pig. Pigs make great bacon though. Everything has its purpose and compromise.

Have a great day,

Larry and I have disagreed on this before. There have been a few high mileage 240d's show up on Ebay with aftermarket turbos. There is also a company in the UK that specializes in aftermarket Turbos. They've put a lot of them on MB's, particularly motorhomes and trucks with the 616 engine. There are tons of them in Europe and the company has been in business for many years. If the process seriously shortened the life of the engine I don't think they could have stayed in business this long, particuarly since they do the work for commercial vehicles. I've talked to people who had it done who were very happy.

I believe there was a factory 616 turbo available in other parts of the world, and this motor should last as long as any other MB diesel, because it has the oil-cooled pistons, etc. However a non-turbo 616 with an aftermarket turbo bolted on is a different story. While I personally think it will last almost as long as stock with up to about a 20% power boost, much beyond that WILL shorten the life of the engine significantly... just IMO of course.

The turbo 616 is now produced in India with the oil cooled pistons but I'm under the impression it was not in production when MB was making the 123 240d.

If MB did a factory turbo on this engine I would be totally shocked if it was not changed to the oil cooled pistons and any other beefing up necessary.

That said, puttin an aftermarket turbo on a non turbo 616 will reduce engine life. There's no way this could not happen unless you were to drive it mildly. It's hard for me to imagine someone who bothered to do this modification would drive it mildly.

I still say if you want a race horse, go get a race horse. Don't try to make a pig into a race horse.

I hope no one thinks that since I am calling the 240D a pig that I am not a fan. I am a HUGE fan of the 240D. But it was designed to be comfortable, economical transportation with long term durability. It was NOT designed to be a race car.

Have a great day,

Here in Colorado, people might want the turbo, not to drive it like a race car, but simply to overcome the problem of altitude.

When I worked for Chrysler back in 1980, we had a 225 slant six in a pickup truck onto which we adapted a turbocharger. It ran excellent and kept within 1/2 length of an identical pickup equipped with a 360 4V. Above 70 mph, the 360 did walk away, however.

We all were amazed by the driveability and fuel economy of the 225 when compared with the 360. It would do everything the 360 would do on less fuel. What we failed to realize, however, that people buy pickup trucks to do serious work. If you loaded up the pickup and took it out on a 90 degree day, uphill, the turbocharged 225 would get into some serious trouble in a big hurry. Chrysler did not want people showing up with cooked engines and the electronics were not sophisticated enough to deal with the heat and the increased power at that time, so they declined to produce it.

The point here is that both Larry and Kerry Edwards are both right. If you put a turbo on an engine that was not originally designed for it, you can get still achieve the same longevity, PROVIDED, that you only use maximum power very intermittently. If you merge onto a freeway and use maximum power for 15 seconds, the engine will not be harmed in any way.

HOWEVER, if you think you can run a 240 with a turbo at 100 mph, using maximum continuous power for an extended period of time, then you WILL seriously shorten the life of the engine, as Larry has suggested.

It all depends on what you do with your right foot.

I strongly agree. My TD is a total DOG without boost. But once the the 12psi boost kicks in, it's a completely different engine.

man...colorado...hahaha i really hate climbing that C470 everyday to go to work...i really want a turbo in my 300D '78
