Dimensions of OM60X turbo exhaust manifold

G'day Folks,

Does anyone have a spare OM601/2/3 manifold gathering dust somewhere? I'm after the centre distances - centre to centre exhaust port spacing for the first four / the complete four parts of a turbo exhaust manifold.

The reason is that my attention has been drawn to some chaps on youtube who have just bolted turbos to M102 petrol engines and left the stock injection system to cope with the extra air!

That sounds like fun to me

So if a four pot OM60X turbo exhaust fits on my M102 without too much arsing about then I can play Mercedes lego!

IIRC there's no factory turbo 601 and the turbo 602 has a single piece manifold. If the port spacing and shape work, you should be able to use the front section of a Euro/US 92-95 603 turbo exhaust manifold (upside-down in this picture) -



The aft section of a US 86-91 603 manifold might work but it has the goofy collector and top feed arrangement to allow a trap oxidizer -

I measure 290mm between corresponding #1 and #4 manifold bolt holes on the head so I'll say 96.67mm bore spacing.

According to wikepedia (in Dutch) there's a turbo version of the OM601 fitted to sprinters - but I'm guessing they are as common as rocking horse droppings.

Mercedes-Benz OM601 - Wikipedia

I don't know why the information hasn't been transferred to the English language page - there's a lot less information there...

...anyway thank you both very much.

This guy on BW is saying he just fitted an OM603 turbo to his 1.8 litre M102 and now he can go back in time =>

My 190 1.8 TURBO - Mercedes-Benz Forum

No pictures of the engine bay just yet. Two videos full of hissing and giggling - and there's another 1.8 M102 turbo conversion on youtube too - but again no engine pictures...

...mention of similar goings on on an English W201 site though.

I'll make some measurements of the M102 head tomorrow - thanks so far

Holes on a M102 head

Doesn't look like the OM603 manifold will fit.

The distance from the furthest holes on a M102 head is about 370mm



Spacing between the holes on the exhaust is about 103mm

I took a gamble and found a pretty rare OM601 turbo exhaust manifold but that doesn't fit either



No shock there really but I thought it was worth a punt

Anyone want to buy a rare OM601 turbo exhaust manifold?

Yep that's plan B

Now I have my TIG welder up and running I've just got to learn how not to get the filler rod stuck and then I'm golden...

...I was hoping for a quicker solution though

KKK turbo - So how big's your flange?



Does that look familiar to OM603 owners?

(And you would have thought that they would have renamed themselves from KKK wouldn't you?)

603 owners will be more familiar with its bigger brother -



Maybe they were inspired by another organization - Katipunan - Wikipedia, the free encyclopedia

Maybe a plan A.2 for a quicker solution.



A Mosselman turbo kit. But I am not sure they still make them...

Plan A.2 would be good but I'm on a budget and I can't find them any more - it is nice to see the parts they provided though so thanks for the pictures

That plan A.2 turbo hangs pretty low - I'm thinking how mach4 couldn't fit a federal 617 turbo in his 107. Does it clear the 201 frame?
