The second engine was (is) not as good as the first and was mounted in
the CITROEN ZX/XANTIA and PEUGEOT 306/405 and is now replaced by the
XU10 8v turbo 150 HP in the XANTIA/406 (this motor was first mounted
in the XM/605 then in the EVASION/806).
Now the ZX/306 use the new 2.0L 167 HP (six speed in the 306).
I'm sure the diff in US/Euro spec was due to the cat converter.
(I think similar diffs will be found for the 505).
