Convert the Audi B3 1.8 with KE to 2.0?

Hello Have again 4 rings on the car. I am more than only happy but he burns slightly oil (in and again blue smoke when warm) and oil pressure when Warm in the stand at under a bar loud indicator. 240t he has already run and I am sure that he should get a new heart. Since he is already equipped with a KE I just don’t know if I just make the same clean again or nen 2.0 he. Brakes in the back I want to convert anyway on discs so… well, someone already has Would only like to know what else I have to change everything and what I have to pay attention to. Quite simply I need a decision help! Engine and transmission (4+E) have to get out. New heart + normal 5 gear in! Please save yourself stupid answers!!! I’m not a small 18j Prolet anymore but I’m talking about stability and safety!!! Sitting children in it! MFG and thank you for helpful answers Benny
