I was wondering if the a4 b7 may suffer an engine swap to a 4.2 fsi , eather the rs4 one eather the s5 4.2 fsi engine, id the engine bay is large enougbt and so on and so forth. My car has arround 270k km on it and it kinda asks for a replace , i dont want any other engine just the 4.2 fsi one. (Because the bentley continental w12 is kinda expensive )
I'd rather have the s5 4.2 fsi engine if it fits in because its cheaper as engine buy.

I forgot to mention that the taxes on a 4.2 engine are too big in my country so it would be cheaper for me to build one on my beloved a4
