Thoughts about the Polo GTI 1.6 16v conversion

So I'm thinking about putting a AVY/ARC From a polo GTI in my 1.3 MK1

The 125 standard bhp seems really appealing to me as i drove around with the miserable 1.3 with the 4 speed box for a while now

So, is this engine reliable and is there a guide on this conversion
What modifications need to be done

Plus i was wondering, does this engine use similar parts as the 1.6 8v AEE from the 99 polo, for example the throttle body, sensors, etc..

I'm asking because when it comes to parts for the AVY or ARC it's almost non existent over here in Egypt but the AEE Is everywhere with all it's stuff
