Seemed like a nice setup but heard a few mixed reviews so I went the #5 route and had them rebuilt and painted with epoxy for less than 20k. Just my .02

Also...the hp rating goes down if you only do the half conversion because they have to use a smaller u-joint to fit in the trs helmet. Food for thought.
