So, let me get this right, you have a 1Z head, that is fitting on you 1.9l AAZ, and a AAZ head can fit on a 1.6l, so, this means I may have to buy a new head?
If so, what do I do with my pistons? DI pistons are far from the same as my lowly 1.6l pistions.
Please let me know as my motor is sitting in pieces right now, and have pump just about ready to head to Giles, and a 1.9l idi head to send to Dave...

So far, there aren't any 1.6 TDI pistons available, though Mr Prothe says he's working on it. Doing a little looking, the 1.2 TDI PD engine has the same bore and stroke, but I don't know if the pins are the same size and in the same place as on a 1.6.

i bet they are... or pretty damn close to it. they really seem to beef up PD engines to withstand much more abuse than they actually receive... which make them great for tuning :wink:
i wonder... 1.6PD? :twisted:

But does a PD head fit on a 1.6 block? Looks like some one elses turn to create a new franken motor.

I am not sure how 1.2l can have the same bore and stroke, as this would make it a 1.6l, unless head volume is way, way less.
If indeed the head volume is .4l smaller then I can't see why it wouldn't be the same engine, VW is very smart, why build a different block (R&D, manufacturing) when you already have one that will work, $$ and all.
If the head volume isn't .4l smaller then either the bore or the stroke has to be different, one hopes it is the stroke!
Though this does give me some hope as to a top secret project I am working on!
And on that note, does Mr Prothe have any expected finish date, and a cost?
I will have to PM him to see…
So very promising!!

Because a 1.2 is a 3 cylinder.

A tdi engine that uses a small cam driven injection pump with one pump per cylinder. They mount in the head under the valve cover, but are electronically controlled.

PD = Pump Duse - German for Pump Injector / Unit Injector.

there were many diesel models produced.
there was a 1.9L SDi non turbo direct injection engine. also a 1.9 IDI N/A. then theres the mechanical injection 1.9LTDi using the Bosche VE injector pump. there are few differences between the first TDi's and the AAZ - injectors, camplate, pistons.... no precups... not much more.
lots of stuff is interchangeable.... great aint it?
so the 1.6 is 76.5mm bore right? surely theres a TDI piston with that diameter.

The 1.2 mentioned above. Elsewhere, someone found they cost $250 each.
