You'll need a higher flowing fuel pump if you go for a map, keep it from leaning off under increased boost,
As for the cv & cambelt are you after info on how to chnaged them or where to buy ?
Personally I wouldn't bother with the water pump, but it's your car can do what you want 😀
It's best off to do the pullies/idlers too when changing the belt,
