Alfa 147 should be quick what’s enough? 120 ps or 150 ps?

Hello guys I want to lay down the 147 sometime this year but the new one looks so bad 😉 now I wanted to ask you if the 1,8 already is enough or if it should be the 2,0 I just want to fly forward driving mostly city actually.. but on the track he should make his 180,190 loose enough for me already. which engine would you recommend me so? Greetings
