Oh. It _looks_ the same as the old one (externally).
Are you sure you're not referring to the 1108cc FIRE engine? The 899cc (that he has) is a _slight_ modification of the Italian 903cc, which is descended from the old 903cc 45bhp engine they fitted in everything (Uno,
127, Yugo etc).
I'm _sure_ it's still an overhead valve though, but they've modified the rocker gear with basic hydraulic tappets to shut the engine up.
I'm also pretty sure it says it's a FIRE engine, but most places only mention the 1.1 as being FIRE.
I've done a bit of rooting around, and found the page below. I actually googled, and found someone with a maxxed out Cinq. He'd fitted silicon hoses to a 1.3 Fiat engine, put a Seat ???? Cupra turbo front splitter, and half the car was primer grey.
I then found this one.

That is some _seriously_ illegal tint on the front side and front windscreen there.
