Would an HDi really be that unreliable with a sympathetic stage 2 tune? I'm not sure.
Clutch will need sorting certainly and it'll show up a weak LP or HP pump, but otherwise it shouldn't be that bad unless it's a particularly leggy or neglected example. After all, stage 1 (140/150hp) tunes on a HDi 110 aren't chronically unreliable that I'm aware of.
A 1.8 bottom end is lovely and it should have been the basis for a great engine, but sadly Peugeot chose to quite deliberately restrict it, presumably to keep a clear gap between it at the 2.0 engine, and removing those restrictions properly isn't a cheap process - head, cams, manifolds and management basically.
As an aside, since the whole reason for pondering a 1.8 was insurance, surely any tuning throws that argument out of the window as a modified 1.8 / HDi would probably cost more than a standard GTi-6 to insure?
