2.0 8v conversion

I’ve been watching this series of videos on a 2.0l 8v conversion with twin dellorto carbs

It really appeals to me, because I’m old school. I don’t do computers but I’ve built plenty of carbs, and many tuned air cooled engines. This would be a cool conversion on my sons Driver in the future.
Hardest part would be collecting the parts. I like the intake and exhaust set up. Might be a bit more clearance for the radiator on a mk2. Looks like he used a 02 gearbox, driveshafts etc, so looks straightforward in that respect. Looks like it takes a gti clutch too. Only bit I don’t like is the alternator belt set up. Very little of the belt runs on the water pump pulley. Will require a very tight belt which will strain the bearing. Should really have 90 degrees of interference on the belt. What alternatives are there? I’m not much of an expert on the water cooled parts and what mix and match parts can be used. TIA

If you take a 2.0 8v from a mk3 (or mk3.5 cab <-- cheapest option) would you not keep the mk3 alternator and pulleys, giving you a serpentine belt set up. Would that help?
