"LANCIA DELTA FWD"
Advertised as 'FWD' thus it doesn't seem to be an Integrale, though it has an Integrale body kit on it. Also note that it is 'B' registered, which I'm fairly sure is before the Integrale was released (need someone like J333 EVO to confirm).
If this is the case then it is well overpriced at £2K, unless it really has had some good modifications done to it. I suspect it's actually a 1.6 Delta HF Turbo (as per the heading) with a 2.0 litre conversion. And a crank is not going to be cheap to sort out...
Edit: From Wiki (I know, not the most reliable of sources but it came up!)
"The Delta range was first introduced to the United Kingdom in 1980 and remained virtually unchanged until 1986, when small changes were made to the cars' body shape, the engines updated and the four-wheel drive model introduced."

Looks like the Integrale wasn't released until 1986, therefore a 'B' plate (1984 - 1985) cannot be an Integrale unless it's had a plate change.
