3.6 v6 - Superb/Passat/Porsche

[RacingGreen]

I see that this was discussed many years ago about why the Superb only had 260ps and the R36 and CC had 300ps.

 

The comments suggested it was purely remapping but a look about now and the Skoda only gets mapped to something approaching the VW figures but not to the 320 that can be had on the Passat.

 

This suggests some other differences - I've trawled t'Internet but can only find a passing reference to a different intake manifold on (posdibly) earlier Passat's. 

 

Anyone got any thoughts / suggestions on this?

 

Also, is the more recent Porsche 3.6 remotely similar to the Superb / Passat engine?

Afaik there's no similarity between this engine and the much more recent 3.6 used by Porsche, Audi, etc..

This one is a "VR6", meaning it is a very narrow-angle V6 - 15 degrees, I think - with a common cylinder head for the two banks: It's more of a wiggly staright 6!

The current 3.6 is a normal V6.

Thanks Mike - I was thinking about the earlier Toureag / Q7 / Cayenne and R36 circa. 2005-2010ish.

 

I've found a few bits on the web now - I'll rip them off and post them up but there seems to be lots of minor differences in crank, pistons (not rods though), cams and valves meaning many different part numbers but they take the same head gasket. On one model Porsche made their own inlet manifold but otherwise the engine was the same as the other VW - the Skoda with 260ps seems to be the low power model but nowhere can I see what makes the difference. Some versions are higher compression (but not the R36) and there are some subtle differences with bore size between the various engine code versions.

 

An admin on another vw owners forum went to the trouble of getting ETKA codes for the R23 vs R36 and the 

 

There's been much discussion about cam swaps etc but mainly with the though of making 3.2 top ends fit on the 3.6 because Schrick only do R32 cams!

 

The 3.6 is actually 10.6 degrees, the 3.2 was a bit wider splay.

 

The tricky thing is that the main discussion for this engine seems to be in North America and there are various engine codes for vehicles released in Europe, N. American and the Middle East so it all takes some unpicking.

Just bumping this - wondering if anybody has stumbled across anything on the net about this?

 

I've going to be getting a V6 Superb soon and interested if there is anything beyond a full engine swap that would get the bulk of the R36 unmapped power ...
