Chopper,

So far this is all I have had to chop out of the subframe. And I will need to weld something back in there. I want to run the PS lines throught the subframe so I will leave a hole there for them to go through but I am going to see how it fits with the PS lines running externally too.

I didn't need to get stuck into the drivers side engine mount the way I did, I just did that to get it out of the way whilst I was playing around with rack position.




Enders, You can come around and have a look if you want, let me know when you want to comeover and I will PM you my address - or ring me if you still have my mobile no - it's still the same.

I haven't updated for a while as I have been very busy with work almost every night for the last 2 weeks and will be for about 2 or 3 more weeks but I have finally spent the afternoon doing my first set of measurements for how the WRX rack performs on an otherwise stock UC Torana front end.

The Rack is mounted at the same vertical height as the Torana one originally was and is approx 6mm further forwards. To my pleasant surprise the bump steer curve has come out almost identical to the bumpsteer you get with the A9X arms on the HQ stubs in bump travel and pretty much a vertical line in rebound travel so I would go as far as to say it looks to have a nicer bumpsteer curve than the A9X setup.

I currently run the A9X setup on my LX and it feels good for lack of bumpsteer and this is supported by the measurements I have plotted for that setup so I am pretty happy that the WRX rack looks to be better again.

The Ackerman angles of the front wheels are ever so slightly different to the a9X and UC setups (I expected this since the rack is 6mm forwards.) I can do a little grinding on the alloy bit of the wrx rack and move it at least 3mm further back so it will be so close to std UC that I won't even be able to measure the difference with my instruments.

Interestingly the WRX rack has an additional 5 to 6mm per side you can turn before it runs out of travel as the UC steering arms hit the bumpstops on the lower control arms first.
I reckon I will modify the steering arms slightly to improve the steering lock. I did a bit of a measurement and I can get about another 3 degrees steering lock if I do this.

At the moment it is 2.6 turns lock to lock - nice but will be about 2.75 turns lock to lock when I mod the steering stops to turn a little further.

The std WRX tie rods are about 10 to 15mm too long so I had to go with no lock nuts to do the test fit and I could just line the front wheels up straight but the earlier subaru tie rods are about 10mm shorter and are threaded for an extra 20mm or so, so they will be perfect for the job without even being trimmed.
The Magna tie rod ends are spot on and do not go close to binding so all looks good to me.

If I had a Holden V8 in my LX , I would be going with this exact setup but unfortunately it doesn't clear the sump on my engine so I am now going to have to ream out the A9X steering arms I have and mount the rack about 10 to 12mm lower to look for another suitable setup to go with my engine.

I'll post some of my measurements and pics when I get some free time.

Imagine trying to steer this one

Mat,
did you need a car to dummy fit it to?

[hatchssv8]

same topic but different means.

Has anybody tried/investigated fitting these types of electric power assited steering.

http://www.motorspor...steering_system

Just a thought at this stage. I have no idea of cost to buy nor to fit and make it work in a LX. I wonder if there is enough real estate in an LX to accomodate this kind of unit. Not sure if these coloumns have a collapsble shaft either. Too many questions.....brain freeze..

yer, whats the go with that electric power steering?
anyone herd of it or used it ?

heya guys
i e mailed motors sport electrics about their electronic power steering unit and this is the response i got.

"SORRY EVAN THIS IS A RACE CAR ONLY UNIT AND IS NOT ADR APPROVED , COST IS AROUND , $7000.00 AS I SAID IT IS REALLY AIMED AT HIGH END RACING CARS.
CHEERS."

doesnt look like it is a option. dam

I noticed on e-bay last night there was a slr for sale stating it had power steering fitted, but had no photo's of it the add stated that photo's of the car could be view on the n.s.w torana web site, only one pic showed the top of the p/steer resivoir I wii try and e-mail him for more details.

Cristian_O - I have been on holidays so I have only just seen your question.

I have done heaps more on my power steering setup but it is a fair way from being fitted to the car because I am not just doing steering, I am also doing tubular control arms, improving the suspension geometry and a big brake upgrade on this front end before it goes in the car.

To mount the WRX rack where the original Torana one goes needs a bit cut out of the front subframe to clear the servo valve but that is all. I have actually worked out a way to mount the rack another 18mm forward and still get all the same bumpsteer and ackerman angles it does reduce the directness of the steering from 15.5:1 to 17:1 which is still pretty good - I don't know if this will stop you having to notch the subframe though but it would make the notch smaller.

You need to use a pair of short HZ power steering arms and then get some Pinto bumpsteer adjusters and machine the steering arms to suit and then use a sperical rod end rather than a normal tie rod end.
This is how I am doing my setup now but I am still mounting the rack back as far as I can and 20mm lower and using LH steering arms for a super quick steer.
I'll post some pics a bit later of how I am doing things.

Axistr,

If thet's the yellow one, there were quite a number of pics of this car shown on the Toranafest galleries a few weeks back including plenty from underneath.

I had a pretty good look at the pics but they were not taken from an angle which you could tell how far back the rack was mounted or how much the subframe was modified to make it fit.

It was definately a Cortina rack and pinion though.

Hi Matt, I have got hold of a 2002 subaru outback p/s rack and I'am going to try and do some testing my self, how are you obtaining the rack ratios I don't now if they are any differance to the wrx racks.

check his car domain page chopper... good reading there

chopper I have a full set of flairs off an LX Hatch and the rear bobtail and front spoiler.

[ozyozyozy]

hello mat. those bushes your using in the front end. can you tell me what there from and where you got them please? im very keen to look into them. have you sourced the lower arm bushes yet?

[Toranamat69]

G'day Chopper - still heaps to go with my whole front suspension.

I have tons of parts here so I am the hold up - just seems every weekend I have family visiting or places to go and I have not been getting time to get stuck into it very much - just a few hours here and there. That and starting a new job just before x-mas has left me pretty stuffed after work during the week.
Very frustrating really because I have most of it worked out in my head - in theory anyway if it all works.

Saying all that, if I put in a few weeks of hard yakka I would probably be at the point fairly soon where I need my new brakes and coilover shocks to go any further and I don't have the cash lying around for either of those at the moment.


OzyOzyOzy,

Do you mean the Del-a-lum bushes? If so the top ones are from these guys.

http://www.globalwes.....d shafts..htm

The kit number is 1012 and they suit the 64 to 72 Chevelles.
You will need to make custom cross shafts to make them work on the Torana - they are so close to fitting the sock cross shafts but unfortunately there is just not quite enough thread on them. They will suit the stock upper control arms still though.

I never managed to track down any del-a-lum bushes which will press straight into the stock lower control arms although I didn't look as hard as I could have. Since I am making custom lower arms anyway I just got some lowers to suit the Chevelles and will make my custom arms to suit. They would not actually be that hard to make up a set if you are any good at machining - I just don't have access to a good enough lathe so I bought some which I can easily make do with.

great thanks for the info. i was going to look into making some but as you know time is always an issue.
