I doubt it as the 2.8 is a Fiat Sofim engine and the 2 litre is a Peugeot PSA engine I think you will find. From memory the 2.8 Sofim has two large bolts at the top and two lower down as opposed to a few more smaller ones on the Peugeot engine. But I stand to be corrected .
See if you can find photos on eBay of the two bare engines for sale to compare.
