G'day Tony, thanks for the feed back. More information can be found on this forum under the heading power steering kits, I started it as an update for members to save them time reading through so many pages on this thread, and contains all my direct contact details. Firstly I would like to thank GMH-torana forum members for their support. To date I have now build and supplied to customers 130 power steering kits. I originally thought somewhere around 50-60 kits would be it, but the request for the kits have been slowly increasing over the past few years.
To answer you questions"
1) Power steering kits start at $2,695 and the most popular variable ratio power steering rack kits are priced at $2,995
2) I generally keep 3-4 rack kits on the shelf so we can supply a kit as soon as you are ready.
3) Yes we have had a few customers fit electric power steering pumps to supply the hydraulic pressure, Electric pumps from Mercedes c180, Holden Astra and Toyota MR2 have been used, Pressure around 900-1250 psi is recommended, just check on the current draw as I believe they can draw a fair amount of amps on initial start up and a decent alternator of around 85 amp would be required as a minimum.
