certain Renault and Volvo engines use a 148 tooth timing belt with a width of 23mm on the face of it that sounds like a good upgrade for the Beta (19mm) if the tooth pitch is the same, anyone know? and is 23mm ok I know that guy croft does or used to do a 1 inch belt but don't remember if it required any mods? dayco part number is 94600 as opposed to 94064 for the fiat/lancia 2 litre belt. the Renault Volvo belt is used on cars with up to 204hp so should be well up to the job of a beta
