Retrofitting Power Steering - what is the best option?
Discussion
Great information.
So if you were doing this again, knowing what you know now and the information you now have available, would you say it is straightforward?
From what I see, apart from sourceing the components, the fabrication part looks like:
1. Joining the top end of TVR column (with half ring) to Corsa column.
2. Welding the top part of the TVR tilting bracket to Corsa 'Christmas tree'.
3. Cutting the TVR bottom inside shaft, and welding it to the Corsa one.
4. Fabricating a new 'collapsable'lower outer shaft.
5. Working out and fabricating the pedal box bracket.
6. Fabricating a new bracket to fit second speed sensor to crownwheel.
I am tempted to start this, but the Impreza / Saxo route seems a lot less complicated, cheaper and only needs a splined shaft made hexagonal to work.
And, apparently, it is also very similar in feel to the TVR PAS
Am I missing something?

No, it’s not straight forward, especially judging from your fabrication summary list, I’m very sorry if I’ve lead you to believe it is straight forward but I have previously said it took me a whole winter. You could spend loads of evenings just trying to perfect the main column bracket on the pedal box, well I did as I enjoy my projects.So if you were doing this again, knowing what you know now and the information you now have available, would you say it is straightforward?

Yes, a decent E-PAS ECU which isn’t cheap.I called David today at DC Electronics and he confirmed my EPAS Lite ECU is no longer available but he may consider letting you have one of his spare Lite ECUs. Their Pro Street ECU is primarily designed to work with the Pro Street column but David is going to investigate if its configuration parameters would suit our requirements.
The Impreza rack conversion wasn’t around when I installed my E-PAS and maybe that’s why I put so much effect into E-PAS plus I enjoy a good challenge. I'm pleased I did as the end result is the best of both worlds, light for parking and manual above 40mph, its brilliant and 100% reliable.

I used a controler from http://www.easysteer.co.uk/, £ 125, very easy to install and works really well. It was easy to program the different speed levels. I use it on a Corsa C EPAS, have not had any problems after one year
I drove a converted Chimaera just completed by Racing Green. I had a manual and thought that the extra effort at walking pace was a worthwhile trade off for the extra feel. The RG conversion was most powerful at low speed and once under way was all but unnoticeable. In fact I couldn't tell the difference, but I'm not a subtle driver.
I was tempted.

2 years ago, they quoted me for fitting an LS in my SD1. £19,000+vat http://www.lloydspecialistdevelopments.co.uk/vehic...
I bought the Chim instead

^^^This! Latest was £1500 + VAT, supply and fit. Phttp://www.lloydspecialistdevelopments.co.uk/vehic...
retty good value when you shop around. Full assistance at parking speed, tapering out to nowt above 30 moh. Lovely!
ETA. Racing Green didn't do it anymore when I called them 2 years ago. Haven't opened the link but they admitted they needed to update their website at the time.
ETA - Again. Have opened the link now for RG. Website entry was 2008. Doh!!!

Im in the process of fitting a Corsa B electric power steering to my car. Its a job I am going to myself or at least the majority of it anyway, the welding of the shafts will be done by an expert welder.
A big thank you to all who have taken the time to post pictures and details of there work it is very helpful indeed.
one question I have is about the controller, it seems some are happy with the adjustable dial to increase or reduce the amount of assistance others say its to much and loses its feel.
There is now advertised on eBay and a company here in the UK called Easysteer a control unit that measures the amount or torque you put into the steering wheel, below is what they claim.
"""Our new system will constantly analyse the force applied at the steering wheel by the driver and automatically adjust the steering assistance level. So, if the driver is applying some force at the steering wheel (for example when parking) the steering will automatically give the maximum assistance. If the driver is on the highway, he will apply a small force at the steering wheel and the steering will automatically turn OFF, allowing the driver to have a very precise steering at higher speeds."""
It goes on to say that there are 5 levels of assistance all dependent on the amount of force you put on the wheel. in theory if this is correct it sounds the perfect solution, just wondered if anyone had any feedback on it I have ordered one to try so will post up the results when I have it fitted and working which wont be for a few weeks at least.

That's a very realistic price to complete a properly engineered LS conversion, Top Cats racing would have done the conversion for you too.. but I believe their prices are higher.
There's a lot more to fitting an LS engine than you think.

Should you require any further measurements, pictures or assistance please do not hesitate to send me a pm and I'll reply with my telephone number.
Good Luck with the ECU & controller.

I'm in the Scoby hydrolic PAS camp, question is how much should I expect to pay for someone to do this conversion ( from standard TVR manual) ???
If TVR engineer on here (John) is still doing them, might be worth a call?I'm in the Scoby hydrolic PAS camp, question is how much should I expect to pay for someone to do this conversion ( from standard TVR manual) ???

Many thanks Stevesprint thats very helpful. I have had a good friend get the top part welded he also then had the weld tested with a ton of force so thats not going anywhere. The diagram printed out perfectly thanks.www.stevesprint.com/TVR-Griffith-Docs/EPASBrackets...

What Gauge/ thickness steel did you use for the bracket I see you strengthened it by adding support at the back. also when you had the lower section welded did you just weld one piece to another or did you sleeve over the top of it? and weld again. I know your set up works as youve had it installed now for 4 years so I am confidant that your way is the best way forward.
