you can buy Mazda 12A engines online- use the carbureted one- the NSU is front drive, however, and uses that bizarre semi-auto tranny- so, you see, your problems with the NSU are gonna be more than the unreliable and dubious engineering of the engine- since you can't use the Mazda tranny, (RWD) only you will know if the engine will mate to the NSU bell housing- somebody must have tried this, so before you go tearing your NSU apart- find a NSU/Audi forum and see if you can find info on this- my thoughts: probably won't work- why would you want to, to daily drive your NSU?! just buy an old Mazda rotary coupe- the Japanese are the only ones who ever got this engine right

Yes you can. You need an adapter plate between the engine and Tranny, and you need to make a new motor mount across the front (combo of NSU and Mazda). Need adapter for power steering pump. Different wiring. Oil cooler, and you need a reducer to run the torque converter off of the engine oil. There are other things, But it can be done. And it works very ell.
