1.4 S engine question

Recommended Posts

I'm looking at buying a Lupo that says it's a 16v 1.4 S with 75 hp.

Wikipedia says there is a 1.4 16v 100hp engine. What's the difference and what needs changed to make mine become the other?

Are there other differences like the gearbox or ratios, final drive etc?

The differences between the 75bhp and 100bhp engines are

Stronger pistons

Different cylinder head with larger intake and exhaust ducts

Different camshaft timing

Different throttle body

Different exhaust system

Aluminium sump

Different software including ability to advance ignition timing for 98ron fuel

Gearbox is also different.
