Italian Volvo 850 T-5 2.0 vs T-5 2.3

[Juhis]

Does anyone know the differences between 2.0L (B5204T) and 2.3L (B5234T)
Volvo 850 t-5 cars?

I know that the engine stroke is shorter in 2.0 version and it has less HP
and shorter MAX torque area than 2.3 version.

Performance?
Tuning?
Exhaust?
Suspension?

Any information is helpfull.
