1.9 TDI Head on 2.0 TDI Engine Conversion

Hello, I would like to know if the cylinder head from a 1.9 TDI ATD engine will fit on the block of a 2.0 TDI BMM engine, including all related components such as mounting brackets and engine mounts, etc.

Best regards, Winnie.

The BMM is a 16V engine.
The ATD has a voltage of 8V.
Nothing fits! / Nothing makes sense! / It doesn't fit at all!

It's been a long time!
Hmm, I'm surprised. The BMM engine with a DPF has 8 valves, while the BMN engine with a DPF has 16 valves.



Okay, now it should be correct!

Winnie.

Please read your answer again because it contradicts itself.

And even if you replace an "without" with "with DPF" somewhere, I bet that a BMP file will result when using a DPF .

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hi, that's how I understand it too.
"8-valve engines with DPF (Diesel Particulate Filter) tend to have worse performance."
16 valves are already better from the factory.

It's just a guess, but perhaps the 8V configuration was chosen for the DPF because one exhaust port heats up faster than two, which would bring the DPF to operating temperature more quickly.
This was at least practiced in this way by Deutsche Bahn (DB).

And with the BMR (16V PPD DPF), they then disregarded thermodynamics .

My guess is that it would be better to experiment with separating the 16V system from the DPF.

Hmm, my guess is that when the 8-valve engine was due for a DPF (Diesel Particulate Filter), the 16-valve engine hadn't yet been developed with a DPF, so adapting it to the 8-valve engine was available more quickly.
Back then (I remember a G4), it was only available with an 8V engine and a DPF, while the 16V version was only offered without a DPF. I no longer remember the model codes.

That was the case with the 140 series until they were replaced by CR models.

Only the 170 hp engine was always equipped with a 16-valve DPF system.

That was all there is to it.
Meanwhile, Mercedes has also managed to produce low-emission engines with four valves.
