B3 conversion 1.6 to 2.8

Hello, have an old B3 bj.91 on which I very much hang! the car has installed a 1.6er mono-jettronic (or electric carburetor as it is sometimes called). goes quite well for its meanwhile 75 HP (5 over ori power thanks to small audio VSD instead of cat modification) only the thing should be really brought in. just because I still do this for my old master (who left me the car. i.e. he would really be happy about it if he gets his second spring) because a little bit of juice is supposed to be and also from the balance should be partly good – would I be for the 2.8 V6 from the B4. to reduce circumstances the fronti version. the 5 cylinder is unfortunately a bit more front-loading… cabling in the engine room keeps itself within limits with the 1.6er. the question is how does this look like with ECU. otherwise would be another alternative motor ne matter (proposals please… vll of the 16V fourzyli?) someone has already missed a B3 of another motor? of the further I search for a used thread over winter then (the conversion should come also in winter… first have to finish my Nissan) – would also exchange greetings for Weitec kit + money from the B3 driver + at the end of the picture ^^
