Skoda Octavia 1999 1.9 66kw 4x4 engine swap

[tann]

Hello, i have Skoda with broken engine 1.9 66kw(AGR) what have wastegate turbo and etc. So i want to put 1.9 81(ahf) engine on it what have vnt(geometrical turbo), also bigger injection pump and injectors, So how hard is it gonna be to control the turbo, plus have to change map sensor, n75 valve(because wastegate gate turbo uses pressure, but geometrical uses vacuum) and also something more that i cant remember right now. Also can i use old ecu, or is it easier to change ecu(with 81kw soft) (will 4x4 gonna keep working), and also can i get old key working with new ecu.
