I'll be utilizing power steering in my LSx FC drift chassis. I know a lot of you depower but this is a question for those who retain it. Did any of you swap the power steering unit on the motor? I see some people prefer the KRC drift power steering setup.

What do you guys use that has yielded good results?

a real nifty set up is a MR2 electric power steering pump.
There are some threads on it.(Australian section)

Using that on a LSx powered FC?

Well Ya..The engine makes no difference if the pump is Electric.
It is body mounted.Hook up the hoses to the rack and wire in the pump..Voila..good to go.

Look up MR2 Electric Pump for a Spyder.

The MR2 pumps are pretty cool. Not a lot of those cars around however. And new the pumps with ECU are over a grand. The fluid is like another 100 as well. They are cool and give you a lot of flexibility.

the on;y reason I said Spyder is because it has a built in reservoir.
The older version has a separate reservoir.
All in all they work the same and you do not need the ECU to operate it.
If someone is selling for a Grand then you are getting Ripped.
I purchased a Pump for 175 Canadian...shipped.

The only reason I asked with the V8 is not because the motor selection persay but the space available in the engine bay for all the added swag.

If you happen to have a link laying around, lemme know via PM.

I don't think the car was offered in North America, but the Holden Astra (small family sedan) has had electric-hydraulic power steering since 1999. It was also in the European Opel/Vauxhall Astra and Zafira in Europe. The early TS models (for Aus) or G series (for Europe) had a basic EHPS pump with inbuilt reservoir that only requires 12V and trigger from the alternator. This makes it a really simple conversion, as there is no electronic trickery required. The pump ramps up duty according to fluid pressure, so it is only drawing current when you turn the wheels. If you wanted to make it speed sensitive, you could either run a solenoid to reduce pressure to the rack (for 89> FC3S RX-7, keep the standard pressure solenoid and power steering computer) or run the pump off a solid state relay and control via PWM.

These pumps are plentiful in Australia and Europe. Way more common and cheaper than the MR2 Spyder pumps. I just got one delivered for AU$100 (US$70). Shipping to the US from here shouldn't be too much either. Look on eBay.
