No I quoted the maximum listed for each engine, not knowing what generation D5 you have. Looks like the 163hp had either 340nm or 420nm depending on year. Still a huge difference and, what's more, coming on 1000rpm earlier and continuing for a long plateau across the rev range, unlike the single (higher) peak of the old engine.
We sadly never saw any D5 engine Volvos or any later diesels at all past 1986 here on these shores, so can only speculate on what one of them must feel like.
But we did get many generations of VW/Audi TDI which are of much the same technology, DI, VNT, etc, to guess the probable difference in power delivery.
Your D24TIC should feel reasonably stout though, all that said, and easily driveable in traffic. Serious lack of power is not usually a complaint, except when compared against something with unfair advantages.
Let us know what your check of turbo boost output and injection pump timing reveals.
