The complete electric power steering pump conversion only saves 4lbs because the electric pump is actually heavier. The electric pump used is from a Mercedes A class (W168) which was impossible to find new. I settled on a refurbished one I found on eBay.

The total savings ended up being 30lbs off the nose because the A/C compressor was finally able to be removed since it shares a pulley with the stock power steering.

I'm going to willow springs on Friday, but from the quick drive around the block, the steering feels heavier. Added bonus-the fan and pump are routed to some new switches on the dash! #race

Pics- new pump with custom bracket, old fan plus weight, new fan's box
Good info - thanks for sharing the weights.
I will note though, you can remove the AC compressor while using the stock power steering pump, you just need to get a shorter belt.
