Gets the weight back, a PS pump and mount has to be added to a crate engine. less complication and space needed with no reservoir, custom lines or a cooler required, potential oil leaks avoided, dash control of steering effort, less power loss.. Overall weight I'm not sure but probably a bit less but the weight is a bit higher and it needs a fair bit of power to operate. And of course here the steering shafts have to be matched up and a support bearing installed although being custom the steering wheel has been able to be repositioned.
Besides I like to try new things although often that gets me into trouble
