I don't know about changing engine, currently as I understand V360Cup has been interesting because cars are very much the same, it has been very restricted what can be done so it is almost same which car driver takes result would be more or less the same, which I think is great, but if engines are being changed, can same still apply or would there possible be someone with more power than other?
It would change nature of motorsport, but maybe it could work if equality is kept the same.
At least 2.3 would help a bit of that 2nd to 3rd shifting, as rev drop is quite big and more torque of 2.3 might give big helping hand there, also wet races might become lot more interesting, when torque is really giving issues with corner acceleration
With 2.0 it is still not an issue, but when I had bit tuned 2.0 it required some throttle control on track when it was wet, power was bit higher than 2.3 and torque around the same, however I had standard suspension and 14" not so good tyres, with your setup things are probably bit different, it turns better and inner rear tire lifting is less of issue if I read V360Cup car specs correctly.
So I'm two minds about it, it will make more interesting, but there is risk of escaping costs and wins to those that have lot of money, unless great caution with rules is being made.
Btw, I did try to outrun 325i once with stock motor and 200 000km driven suspension, it was impossible with my abilities, I felt that I would need lot more grip, also brakes faded out so I was left behind running wide of corners while brakes smoking, servicing of brakes would of helped at least a bit there, my lame excuses
