Just thought I'd give an update. SV8 has been unregistered for the last 3 months because of the lifters, bought a sh.tbox G202 Charade as a daily to get me by.
This is the way I've done the electric power steering pump conversion so far, mostly following a how to on this forum
Here is a picture of the pumps from the Holden Astra TS (left) and AH (right), you can see why people use the AH one.
The following fittings and hose are what I used:
Aeroflow AF573-06BLK
Aeroflow AF574-06BLK
Aeroflow AF712-06BLK
Aeroflow 200 series -06 hose.
Speedflow 741-06
Make a CAD (cardboard aided design) template.
Make sure you're happy with the placement and make some reference points on both the CAD template and pump, all I done was align one of the mounting points with the hole where the factory air box bolts to.
Make it out of aluminum, I used 3mm for the base and 2mm for the ring we rolled, 3 stitch welds and it is solid. The brackets were added after this picture was taken but I never took a picture.
This hose took me an hour or so to make as I had never used the fittings or anything like that, it was all new to me.
Buy the anodized spanners, I tried the masking tape trick and it didn't work, it went through the tape scratched all the fittings.
The factory low pressure return hose will reach, but it kinks a little bit so I made my own out of some spare, no picture for it though.
Mount nearly complete, painting it at the moment then will add neoprene foam to absorb any extra vibrations. It may look close to the wheel arch but it has plenty of clearance.
As for the wiring side of things, I bought some butt joiners to extend the factory 8 gauge power to the battery, use an 80A fuse for this, it is what they used in the Astra. The ground was run to another grounding point closer to the pump to save wire.
For the remote wires, I joined the brown and blue wires and run a single wire to the purple fuel pump wire inside the drivers kick panel, I was going to try and hide it in the engine bay at the fuse box but couldn't be bothered.
For the engine belt side of things, it's simple. Belt part number is 6PK1420, buy another LS1 ribbed idle pulley to replace the smooth one and use a 3mm thick washer to space it out, clearance to the alternator bolt is damn tight but I haven't had any issues with the belt rubbing on it. you can find a diagram online on how you should run the belt.
