Switching from vtto double barrel to helix overdrive

[aaliyan_f]

So I currently am running the vtto double barrel hpfp and was looking to switch to the helix overdrive since the double barrel hpfp has failed the bearing inside the pump is gone. Is it an easy switch over or are other modification required for the switch over. Please help me out.

I think there is a better solution coming from @Hydra Performance

Rather than overdriving the pump using a gearset he's changed the main input gearing to the pump.
