I have a gascket in the garage but i'm heading for bed now so will look later, but from my CAD drawings i did of it the bore centers are 103mm.
If it was possible to change parts from one to the other then i wouldn't have had to build my own turbo exhaust manifolds i could have used one from the 2.3 turbo. They are to long.
I know the 2.0 head will not fit the 2.3. But if you want to keep your hopes up until someone else say the same then its up to you.
