Here are pictures of various 617 exhaust manifolds I've collected and thought it would be useful for some to see the differences. If there are any more variations please post them.

"Hi tuned" T04 manifold, OM617
       

That HI tuned one's pretty! Is that aftermarket?

Where did that Hi Tuned manifold come from?

eBay several years ago. I haven't been able to find any information on it and the seller didn't know anything about its source either.

Thats an awesome find forced!
Seems like your always coming across the cool shit.

Found this in
Google Books

It referres to a Dutch company, Van Zijverden Turbo B. V.

I'll add one

Thats fucking gorgeous!
Exactly what i want for my 616

Any pics of it installed?

Wow, welded straight to the cast manifold .... That's interesting! Don't think I've seen that done before...

I've heard that steel to cast requires a low hydrogen welder for proper bonding. But if anyone knows of where to find another 617 turbo hi tuned manifold is pm me, I will buy one.

OK.Which manifold and turbo is best for a stock 84' OM617 with only IP tweeks and a free flowing exhaust?I'm looking for direct bolt on from another common Mercedes engine.Maybe the original is best?

Intake and exhaust manifolds from a 78-79 300SD. They eliminate the EGR completely and the exhaust manifold flows more freely due to larger passages.

Thanks.That's good info.

om603 euro on ebay now http://cgi.ebay.co.uk/Mercedes-exhaust-m..._500wt_922

looks to me like a 606 manifold, hence the triangular k turbo flange.

That's clearly OM606 manifold. Triangular turbo flange and wide exhaust valve ports.

Interesting maybe I need to look at a om606 turbo to replace my Rajay turbo on my 240d turbo???

Are you sure that the later manifolds didn't narrow up the passages to keep the velocity up on the exhaust gasses to spool the turbo at lower rpms?

Thats exactly what they did because the EGR steals exhaust.

So would you agree a 79 manifold gives better topend power due to better flow while an 82+ manifold with the EGR capped would give better lowend power due to better spooling?

No. With the EGR capped you still have the volume of the tube to fill and the turbulence created by the port.

I'm new here today.

I have an original 240d TURBO KIT new, still in the box..

It is the last one the Wolf Fengler built. What's it worth, anybody interested?

Too bad this will not fit on the 617.




.

Would heat transfer cause issues and gasket failures using a one piece flange on a OM617?By one piece, I mean all exhaust ports and intake ports on one single flange.

I can definitely see gasket issues with that.

Thanks.That was my thoughts but wasn't 100% sure.

Thats why Mercedes designed the larger 4-part gasket to replace the original flat metal gasket.

What are the factory OM617 gaskets made of?Do copper or aluminum ones work well on a turbo diesel?I've only used aluminum and copper on gassers.Great success there.

I don't know much about these, just from Merlot's post.

I did however see on the STT's website they sell a 300D/300GD turbo system that one can get more info on.
