The main reason that ''BIG'' engines make more HP is not because they are big but because they have bigger heads, camshafts, compression, carbs, etc.
The 2332cc we have in the Maluch would have made more HP as a 1914, but at higher rpm.
Also, the standard VW parts are often of better quality than the tuning parts, so a 1600, with so many standard parts, is not a bad choice.
I would concentrate on the intake side of the engine. The intake port and the manifolds. Most manifolds are universal for carbs from 36mm to 48mm and so the top part is huge (48mm) and far too big for a set of 36 Dellortos. This needs to be reduced to 36mm and then taper down to 32mm, which should be the size of the port, also. There is much more, but it would become an article rather than a reply.
