 RA23 steering upgrades, anyone got info? do RA28 or 40 items fit?

I want to get rid of the crusty old steering setup in my RA23, I have seen RA23's with the newer steering setup, but i'm not sure how to go about it.
Is the RA40 or 28 item the newer style and are they compatible with the ra23 (76 model)?
Whats the best way to go about it all?
Any advice/info would be greatly appreciated.
Thanks.

they're all the same old-style steering box (that gets flogged out and worn).
if you wanted a serious improvement in steering, then rack-and-pinion (custom mounted/fabbed to the cross member) is probably the way to go.
Joe (TurboRA28) has done this, but i can't find his thread on the topic.

from my experience i dont think there is any difference between ra23/ra28 and ra40 models steering setup. correct me if im wrong somebody?
rack and pinion wasnt in any celicas until after the ra40 model i thought?? ra60 onwards, maybe sa63 even?
if you want a whole new rack & pinion setup theres a few who have performed this to older celicas/corollas, by utilizing AE71 r&p and fabricating/re-positioning all the mounts etc. onto the ra23 x-member roughly?? but i am not an expert on this at all..
i just replaced or re-built all the components in the entire steering setup, including new steering box internals, and addition of Roll-Centre-Adjusters(bump-steer spacers), to help correct the steering geometry from having lowered the car.
for improved steering with standard-type setup check or replace with new:
tie rod ends,
ball joints,
idler arm & pitman arm,
steering box internals & bushes,
roll centre adjusters,
nolathane bushes everywhere.
shocks/springs,
tyres/alignment,
sway bars..
this is what i found i had to do with my old ra28 to improve steering response and performance..

RA28 and RA28 bits are the same, pretty sure of that.
Some are more worn than other, that's all.
RA40? I reckon that'd be about the same too. Struts are different (slightly), suspension arm length if different (longer by about 40mm I think, a search would clear that up)
Rack and pinion would the way to go, but not with power steering. Being able to feel the road is a good thing in my opinion.
Also have a look at increasing your struts' caster. The design of RA23 suspension is really shit. The tyres roll onto their outer edges when cornering. This is BAD!
Caster makes a huge difference.
We used the lower strut support rod (near ball joint to front of chassis) to pull the wheels about 10mm further forward, then had the wheel alignment redone. Improvement was very noticable.

I would hope so 
If you meant RA23, then yes they are 
BTW, im using a manual rack out of a AE92.

MX62 cressida power steering is practically a bolt in substitute for a RA40

ra40 and ra28/3 steering boxes are not interchangeable.

anyone thought about a xA6x r+p conversion for an early celica?

blackRA28,
How did you go about replacing the steering box internals and where did you buy the necessary parts ?
I don't suppose you were able to get a quicker ratio for that box, say something like 16 to 1 instead of the standard 22 to 1 ?
Thanks,
Mitch.

When I was searching for steering box reco, all I could come up with was new seals/bearings. Couldn't find any place to supply gears.
xA6x crossmembers are close, but the positioning of the control arms make the track way too wide, unless you want to run flares etc. I measured it all up once and ended up like 90mm or more wider, 45mm per side from memory.
The ke70/ae86 xmember/rack conversion really isn't hard. Do end up with a bit more track, but just enough to give you a nice 2 deg neg camber.
Cheers
Joel

For some strange reason my RA23 steering seems to have a closer ration than my brothers. Don't really know why or if it actually does have a different ratio (doubt it), but it feels slightly quicker.

Shit my bad there i wasnt able to track down any different gears etc, i would have to ld u about it, just got seals/bushes/bearings..
i meant re-coed with everything readily available... i think the seals or something in particular had to come from sydney in the end.
