not too sure, but i think the major issue with the 20v s2 motor as opposed to the 10v ur-quattro is the intake manifold, as there is less room under the hood of an s2 as opposed to the ur-q.  the head is higher and wider of course than the wr, but i don't think that makes much difference with the ur-q.  pretty sure the cooling system was changed too, so it'd pay to take that from the s2 as well.  

i'll take some measurements from my s2 and compare it to my 20v ur-q if you'd like, although obviously the 10v wr motor would be different again i'd expect.  actually, why don't you tell me what you need by way of measurements etc, and i'll get them...

I know that there are differences with the manifolds.  In any case I intend to try and get just about everything from the S2 and if I don't need bits I can always sell them.  What things are obviously different between the 20v ur-q and the S2?  When photographed they look remarkably similar.  I can't tell you what I need by way of measurements, but as there is more room under the bonnet of an ur-q (some people would find that hard to believe) I suppose that there is scope for adapting brackets and mountings.

In any case I hope to try and sell my WR engine and its gear before I stick the 20v in.
