I think GM developed 2.8 and 3.6 V6 based on Fiat's input. They used 1.9JTD but I am not sure current 2.0 diesels are based on JTD.
They just do not go as JTD's. I had Lancia Lybra 2.4 JTD. I called it "the killer."
The 1.9 engines were completely developped by Fiat, but the more powerful versions were reserved for use by Fiat owned brands only. still, it was a very good dal for GM/Opel/Vauxhall as they didn't have anything that came close in either reliability, durability or refinement when it comes to diesel engines.
The 2.0 is a development of the 1.9 and GM + Fiat are starting to go their seperate ways now but all parts so far are interchangeable between both, if not the same. Software and injection equipment is where the differences are mostly found. and there's no FPT logos on the cast parts...
The 1.6 used by GM shares the stroke and bore with the Fiat 1.6 engine, but uses an aluminium block. Here's where you see they're setting up their own development again.
The 1.3 is also a Fiat development.
The 1.7 cdti had a lot of Fiat input but the basic design is not by them. they added the common rail system, so to say.
The 2.4 was a terrific engine, had one myself. Heavy though and not many engine bays can take a 5 in line transverse engine even though the design is actually quite compact.
GM sells a Fiat Doblo as the Opel/Vauxhall Combo atm.
I am not sure about 1.7CDTI. It is development from old ISUZU engines but they definitely used some know-how gained from FIAT.
Are you talking about 1.6 gasoline engine or diesel engine? OPEL in my opinion always had better 1.6 gasoline engines if not the best in Europe. Old 1.6 OHC and the DOHC etc. I would say FIAT used there OPEL's know how. However, with diesels OPEL had serious issues. I am old enough to remember OPEL's 1.5d, 1.6d, then 1.7d. Best diesel engine that OPEL had ever in their cars was BMW's 2.5 inline 6 in Omega B.
As for 5cyl JTD, yeah, it was heavy and transverse, but it was FAST!
