i sold a turbo for an s1 on ebay the other week,the buyer seen the pic and description and bought it,then when he received it he says its no use,he has an s2 and since this turbo is watercooled its no use.can you take the turbo apart and swap the cores easily to make it watercooled?also,it has a little play,nothing excessive,since i wouldnt refund him cos it was his mistake hes now saying it has far too much play and is useless,it does have play but the impeller isnt near touching the housing.a bit of play is normal isnt it and is usually taken up by the oil when there is oil pressure?
