differences between the S2 and RS2 rad?

[archiboy24]

Are there any major differences between the S2 and RS2 main radiators? The part numbers are the same except for the last letter.

There are some differences in the coolant pipework, wasnt aware of any difference in the radiator.

Have a search for S2Centrals Samco hose groups buys, i think the answer might be in there.

The radiators are indeed the same... Real oddball on RS2 setup involves different pipework as Mark mentions... Audi figured the pipe routes were fine on many thousand S2 machine, but Porsche somehow convinced them to change it for a few hundred RS2.

On the RS2 one of the lower ports on radiator is blanked off - by an external bung - the radiator itself is same as S2.
