This is the electric power steering pump that goes with our bracket and is included in the complete kit. Made by TRW and is the same as what Porsche Motorsports use in their race cars. This pump costs $1,595 new from Porsche.
Luckily, this pump is also used in Opel and Vauxhall Astras from 2004 to 2008. We were able to source refurbished, used pumps for a fraction of the price. The part number for the pump is GM 93188236. Hard to find in the USA but common in Europe.
