I found this on the net, going on about the mk1's having a better engine than the mk2 what do you think.
The 1301cc Turbo was replaced by the 1372cc unit in 1989 with the introduction of the Mk2 Uno Turbo. For some markets the 1301cc turbo was retained in the new shell until a catalysed version was available.
In the UK the Mk2 Uno T never achieved the same popularity as the Mk1. Its heavier, with a bigger engine capacity and turbo, but lacks the raw tuning potential in the high revving Mk1. All this changes when the mods start anyhow.

The Mk1 turbo is smaller and spins up faster with less lag. The Mk2 turbo can flow more air and is cheaper to have re built. The Mk1 delivers its turbo boost higher up the rev range while the Mk2 is more progressive - Mk2 turbo boost is present across more of the rev range. The Mk2 has 11bhp at max power over the Mk1 but the Mk 2 is also 80kg heavier. The Mk 1 torque curve also has a better mid range to it. Don't believe the top speed figures too much - especially if the car is slightly modified - as then a good one will pull to its red line in fifth (something the standard cars are reluctant to do). Orange-lining in fifth is more like 132mph and red lining 140mph! If you are modifying the engine but retaining many standard parts, the Mk1 has proved to be more reliable and can benefit from the Mk2s camshaft and higher valve lift. Best of the standard camshafts for the road is probably the Punto GT. While the standard X1/9 1498cc cam has the highest valve lift at 9.85(in) and 9.9(ex) its timing - 24/68 68/24 is different to the turbo cams and can deliver power advantages higher up the rev range. Reports from members (typically in motorsport applications) suggest the X1/9 camshaft may also be limiting valve/ engine life. Why does the 1.0 bar mod do more for the Mk1? Well the Mk2 is already nearer this point as it runs slightly higher boost as standard.
