Impreza steering rack mod

[phazed]

There is plenty of information on this thread although a dedicated total modification would be good I suppose.

This really is not a difficult job and can be undertaken by most people.

Happy to point anyone in the right direction if necessary.

My conversion was carried out nearly 4 years ago, has been absolutely perfect and I have not touched the installation since.

Am I right in saying the only bit of fabrication is getting the uj to fit the Impreza rack? And some custom pipes being made up

I read the thread last night and pretty much yes, you will obviously need to mount the pump somewhere and wire it.
Im going to machine the shaft instead of trying to do it by hand.
Rack mount spacers can be bought or made too.

As the above, really simple.

Forming the hexagonal shaft is perfectly acceptable. I did a really good job by hand and let’s face it, you are only clamping the Ford KA universal joint to it.

I'm thinking of using the alternator circuit posted earlier in the thread to trigger a relay but is it suitable to tap off the alternator too as the main feed to the new pump?
Would simplify the wiring a lot, all fused of course.

I think I took a feed from the starter motor, used an in line fuse. Also used the alternator to trigger.

I’m thinking of doing a Scooby PAS conversion, does anyone have a step by step guide for doing this?

[Belle427]

The info is all here but it is a little disjointed as some use the original rover ps pump and some the electric pump.
Im just starting mine using a vauxhall electric pump so will happily provide a step by step when done.
Biggest headache and expense of it all is sourcing the hoses and fittings but im hoping my local pirtek will help.
Its looking like all the parts will come in around £250.

[phazed]

Pirtek isn’t the cheapest way but the easiest.

I took in the items that I needed connecting having measured the length required and left the rest to them.

Half an hour later I left with necessary pipework and all was good.

You will need a proper pressure hose for the delivery of the fluid but a standard jubilee clamped hose is sufficient for the return as it is running at low pressure.

[Belle427]

Theses look like the same adapters mentioned earlier in the thread needed for the rack and pump (random size shown)

Yes a little disjointed as you say, that’s why I thought I would ask. Thanks for the offer but I’d prefer to use a hydraulic rack system.

[Belle427]

It is a hydraulic rack its just the pump thats electric.

Ah ok, I understand, so what are the advantages of an electric pump versus a belt driven one?

I assume ease of positioning

[phazed]

It keeps the front end nice and tidy.

More efficient as not driven by the engine, extra bhp and torques!

and where does the power come from to turn the alternator (now working much harder) that produces the electric to run the pump......

Fair point.

From the electric fairy

I fitted the electric pump in the nose, not in the engine bay. Advantage is cleaner look and away from the heat generated by the exhaust and radiator. Dis advantage is I have to adopt a praying position to check the level, but its never moved as its a jap rack.
