I.e TOTALLY different in style, shape, etc? Just thinking of "other" uses for my now spare PD100 engine, etc?

For example is the octy TDI pd100 engine basically the same block exactly? Or are there subtle differences to overcome? Like maybe I'd need to transfer inlet manifolds, transfer the turbo, etc... Things like that.

Just wondering.

There isnt an Octy PD100.

The superb has a 1.9 PD100 option.

Isn't that mounted longitudinally instead of transverse though

Yeah, different manifolds and turbo etc.

Oh right.... :( How about through the rest of VAG, like Ibiza, Golf, Polo, etc?

Think I may need to consult my "database" to compare the various ATD base engines and see if they differ much.
