Happy to hear that. I just got a S3 intercooler (later one with plastic ends, same as 6R I beleive, off a 27k motor). Only because it was silly cheap really. I wasn't planning on going stage 2+, was only planning a DP / decat. But I think I'll only be HPFP internals + rs4 valve away from 2+ now, so is probably worth the extra £350 or so.
OP. Keep an eye on the likes of Audi-Sport.net and other Audi forums for S3 intercoolers. I picked mine up for £100 delivered, probably because no-one wants such a thing on the Audi forum as it's not an upgrade to them. It is to us though.
