I'm slowly starting to gather information and parts for my CA18DET swap. A while back, there was a discussion in the shoutbox about S13 PS pumps being "high pressure" and S12 ones being "low pressure" resulting in overassisted steering when using S13 PS pump with S12 steering rack. I want to keep my S12 steering rack so that means keeping the low pressure system. I thought about using the S12 PS pump that's currently on the CA18ET but it's Mk1 with the v-belt pulley and I read somewhere that you can't fit a Mk1 PS pump with a S13 pulley because the spline is different, so my questions are:
1. Can I fit a Mk2 PS pump pulley on a Mk1 pump and if yes, is it going to fit the S13 CA18DET properly and will the pulleys line up?
2. Does a Mk2 PS pump fit S13 CA18DET?
3. What's the powersteering setup in your CA18DET swapped S12?
