I initially used the fluid designed for the e46 rack but it was not compatible with the pump and caused frothing/pressure build up. I am now using a Comma MVCHF fluid, which is compatible with the pump and also rated for BMW/Mini. I have been informed it should be ok to use with the E46 rack as well
I put the required fluid by BMW in forst but it f
called that because of the purple tag on it you can see in my picture. It was the quickest rack fitted to RHD E46's. I believe the US version also has a yellow tag rack

By far the cheapest variant is the steering rack...
Part number for the UK Vauxhall Zafira is: 1040085003094
Yes, I just routed the pipes to the pump at the back of the engine bay. I'd change to a better-spec high-pressure line hose, though, if doing it again, and I will change it soon, just in case.
Mine is from a Zafira A, which is rated to a maximum of 110bar. Part number is 1040085003094
The only thing I'd do differently if doing it again is the high-pressure hose. I'd buy a proper crimped one rated at 330 bar. The pump only runs at 110 bar for a moment at full lock, but the AN6 screw...
The goal with this build was to have a fun track car that could also do road miles in relative comfort, but above all, it was fun and gave close to the same feeling as my E92 M3 track car. 2 years into the build, I feel like I am finally approaching that point.
As it is almost exactly 2 years...
Crackin day at Croft recently! Don't hear much about the circuit on the track day scene, but I bloody loved it! Fast, challenging and a bit scary.
Car performed very well; it was still on the YSR coilovers with shot rear dampers, but the LSD ramp angle changes have really made the car...
NGL, I've had a bit of a nightmare with this.
I decided to replace them with ST XTA 3 Plus from an E46 M3. They are a 3-way adjustable damper based on the KW Clubsport V4's and a relative bargain at £2000. Unfortunately, after 9 weeks (I was told 10 days) and them still not being put into...
Some people fit this TRW pump to the stock rack on the E92 M3 to remove both the need for cooling and the stock engine-driven pump, which wears out. If the earlier cars had a hydraulic rack, then I'd say yes if the rack fits the E89. Someone asked something similar on my FB post about it.
Electric Hydraulic Steering upgrade.
Been meaning to do a video on this, but stuff keeps getting in the way, so here is a quick write-up.

Yellow are awful and worse on the road than blue. Blue are a good compromise track/road pad. I ran them with cooling and ATE Typ 200 fluid without any issues before upgrading
Don't know if it's common, but it's possibly the easier option. You use an E46 rack and an electric power steering pump. Just need to hook it up to power and connect it to the rack. I'm using a TRW pump from a Porsche Cup Car ( and Vauxhall Zafira!). The good thing is, it doesn't take engine...
You can adjust the ring on the steering column to change how the gears lash and interact. This can help to remove the dead zone but it can also make the car very nervous at speed if you go to far. It's a bit of trial and error. Adjust, drive/check and readjust as necessary. Dead easy to do with...
