Turbo a Non turbo 617.912
 

I know, This has been asked Many times before......

BUT-

Here in the U.K, the Turbo 617 appears to be a VERY rare beast indeed....I would grab one if I could find one, Not sure if there were any imported, or what vehicles they may have been used in....

Anyway, Has anyone just added a pump and turbo to an otherwise Standard N/A 617 engine? Obviously, the Oil-pump would need changing to cope with the extra need of the turbo, I should be able to get a .952 pump. I could even source Turbo pistons, But the rods are different too--After that, It just gets TOO expensive!....

So, Anyone done it to a Standard engine?--What happened, Is it still going?:)

The non turbo engines do not have oil cooled pistons. On the turbo ones there are oil sprayers that spray oil on the underside of the pistons to keep them cool when under the load of the turbo. Turbo models also have a hardened crankshaft to cope with the extra power/stress of the increased output.

In short, a non turbo engine needs to stay that way. Turbo'ing it would only destroy it after a little while. Probably would be a lot easier to just import or locate a turbo engine.

It is so impracticle to do. While all E class cars brought into North America for the US and Canadian market were turbodiesel from 1981 to 1985 save the 240D, the only turbodiesel model in Europe was the 300TD turbo. I think you would be better off finding an engine here and paying the freight via sea, or take a trip across the channel to Germany because I think there will be more there than in the UK.

Good Luck:D

Differences...
 

I know only too well the differences, BUT just like most MB things, they are pretty 'over-engineered' I would like to know IF its been done, AND what happened....

The cost of buying and Importing an engine would be at least 6 times what I paid yesterday for my 280TE wagon!:eek: --Would be cheaper to buy the parts from MB Stealer and build one in my current block after modding for oil jets!

There is a company in the UK that specializes in aftermarket turbos and turbo the 616 and 617, often times in trucks and motorhomes. They also sell autoclutches. I've posted the link here in the past, but if you google turbo and autoclutch their website should come up. They would be the best source of info. I think they've turbo'd a number of GD's. I once met a man in France who had had it done to the 616 in his motorhome and was happy with the results.

Here's their 617 turbo set up with a picture. Only 1200 pounds:

WELL--

Aint THAT enlightening! (TB Turbos that is!)

There is NO way on earth, that they can be doing all the alterations AND supplying headers (Manifolds to us Brits) plus a Turbo, Oil pump, IP, for ONLY 1200 quid!!

Guess they just add an ALDA, adjust the IP, and bolt on a turbo with new headers!

Ill have to contact them just to find out EXACTLY what they DO change!

interesting, i wonder what kind of IC they are using

Where are you in S. Wales? I spent the first decade of my life in Pontypridd.

I forgot about that too, the Naturally aspriated engines don't have the same kind of ALDA for fuel enrichment that the turbo's do, so that'd be an issue as well. They are indeed over engineered, but if you added a turbo to it I'd not run more than 4-5psi of boost. That'd probably give you an extra 10-15hp maybe.

I've got a CAT 3208 in my motorhome which was originally an NA. It has an aftermarket turbo. It is advantageous at altitude but probably not worth the $$. It cost 5k when the original owner installed it in 1983.

Many if not all right hand drive cars were all non turbo because the steering system will not fit with the turbo on the engine. Sorry to break the bad news. But you all have tons of diesel cars that we can only dream about....:(

my dad has an 88 Ford F350 Diesel... the last year before the "Powerstroke" the only diffrence is the power sroke is turboed... well his truck came from the previous owner with a Banks Turbo kit. very nice truck... well after only 130,000 miles it was having engine problems, we took it apart and found stress cracks in the heads, pistons, connectiong rods, and valves. we had to buy all those parts new. its amazing the stress a turbo can put on an engine not ment for a turbo.

its also amazing my dads ening didn't hand granade. :bomb:

That company hasnt yet replied to any of my Emails, but during discussions with various others, it seems that no internal major engine modifications are done by the companies that have responded. Some companies advise an Intercooler to reduce thermal stresses though.... HP increases of around 20-30 BHP have been quoted to me...
