I don't know much about the "Rev limiter" required but it looks expensive. Not sure if it is best choice or someone did a good selling job......

But when they introduced the DFV rev-limit someone reconfigured the engines to produce more power...
DFVs have come with various bore/stroke and valve size configurations over the years and someone came up with a new configuration that worked better at the new rev-limit, hence remaining "competitive" required a rather expensive "rebuild".
A normal DFV rebuild should be much less than 25 grand (7½ if you're lucky), 25 sounds more like the cost of modifying to the new spec.
But the rev-limit does increase the mileage between rebuilds and is closer to what would have been used in period.
