power steering

The cheap kits available atm will prob mean you'll fit and forget as speed sensing isnt available
Saying that its always handy to adjust feel with a twiddle of your knob :thumbs:

Mine got a speed sensing system .:thumbs: that take a pick up from the front wheels.
 
Hi from N.Z. Three of us in my area have fitted PS to our 240zs all using the rack from Subaru Legacy,which needs 15mm cutting from each end of the inner shaft and re threading .After removing the crossmember from the car,and placing the rack on the rack mounts it becomes obvious that the engine mounts need to be altered, as one of the oil fittings on the rack pinion housing points straight down into the engine mount.To overcome this I cut this fitting off and brazed on in a new position facing up,being carefull not to over heat the casting and distort it.Also had to dimple the engine mount for clearance.Some filing of the alloy body of the rack was neededto make it a snug fit on the rack mount Also the short shaft on each end of the rack needs altering and new tie rod ends.I got these from a toyota from memory .One of the other cars has a rebuilt engine mount to give clearance for the oil fittings from the rack .I am using a pump from a Hyundai lantra the reason being the pulley has the correct V and it is a very small pump with a remote resovoir,which I placed on the inner guard under the right side inspection lid.I mounted the pump in the position of the fuel pump,which i was able to do as im using an electric fuel pump.For this i used a 20mm piece of alloy and then bolted the ps pump bracket to that carefully lining up the pulleys. The steering column shaft I cut and welded to the subaru universal joint which i had partly imersed in water to stop heat transfer to the bearings of the universal.Two years trouble free and drives like new.!:driving:Cost of about 200 nz dollars,with all the parts taken from low mileage wrecks at my local Pick a Part.
 
the reason i did this conversion was because of an injury in both shoulders,and was unable to turn the steering on the 240 :unsure:
 
My car was on track yesterday at Le Mans and twice, pro. drivers took her out. Both preferred the PS.
 
Has anyone fitted EPAS to a Z that is progressive (reduce assistance with increased speed), or do you have to manually adjust it? Most of the kit I've seen has a dial that you set for a fixed amount of assist. Am I right in saying that all OEM equipment is speed dependent, in addition to voltage and revs?

I'm trying to make my mind up as to whether EPAS would be help or hinder if not utilizing speed sensing technology.

Mine is manual adjust but what do you need the car to do ?
imo if you could make it speed/load sensing then yes it would be a much nicer system to have.
Once on the road and set you shouldn't find the need to fiddle?
And if you do its no hardship to adjust your knob !

But if you are trying to keep the costs down and have a simple plug n play the manual adjustment is/ would be just as good ... £ for £ :)
 
Thanks for the reply. Thats the feadback I needed to hear. I had it in my head that if you set it high for parking it would then take away the feadback for higher speed driving and you would then have to turn it down.

I've just found someone who sells a"kit" for £300 that includes the rack, ECU, and speed sensing equipment to make it fully automated. The only trouble is, its for a T3 VW. I'll make some further enquires.

Sorry, yes that is right. As said its down to £ for £ and what you want to spend
What I meant on mine is once set l leave it be. i.e half way between light and heavy steering. But if I need to lighten it up its just a case of dialling it in
btw, some control units come with preset rates, but imo they cant be as good

What is on offer for £300 ? Is that a rack or column, from what ?
Be interested to see pics of what parts they use
 
I've found a fully fitted kit for the Z that is speed sensitive for a rather large £1700 lol......

But it is a nice bit of kit with CNC machined brackets and brand new machined column.

The kit I have read about is for the corsa B rack, ECU, speed sensor pickup and toothed wheel that you rap around a driveshaft. The person selling it was quoting £300 for the parts or £400 fitted. This was on a VW camper forum and was for a Type 3 bus. The thread was a few months old and I was not looking to actuallly buy from this guy, just looking at how easy it was to implement a system with progressive assist that is speed dependent. There was also a lot of info on this thread about the other variable the corsa ECU looks at to deside on the amount of assist.
 
Don't get me wrong, I'm in no way knocking your system. I admire the fact that you just get on and do what the rest of us just talk about for several years.
 
It's been so long since I've actually driven the Z, I can't remember what the steering is actually like. I gather it's pretty heavy at low speeds so PAS would be a welcome addition for this but what's it like at speeds above 10mph?. Would you benefit from a little assistance or would it be better with none. Also, on loss of power to the rack, does it make the steering heavier than standard?

Is that power column or rack ?
The early Corsa B used a std hydraulic power rack

As far as I know most (not all) later 99 on cars had elecy p/s, apart from diesel cars

tbh its got to be down to driver preference or ability
For me or others - if you have a disability or need then p/s is a welcome option :thumbs:
As a fast road or track car it would also be a great option

For a minter car it might not be so good ?
Saying that it depends how well you can hide it :D

As for loss of elecy power, the steering still works but becomes heavy

Not so obvious, apart from that little blue knob below the stereo

Still not perfect, but works well :)

A 240 is light enough without p/s, it's the 260 that's the "pig".
