TA22 + rack and pinion

[Sam_Q]

yes and yes.

i have the full S13 front end disk to disk, strut to strut, however you are right about spring width on the front, but i'll just buy some coilovers (there are a LOT around for the S13) and then some silly car camber tops and i should be right as rain. my main concern is having reasonable camber for street driving with the full S13 front end. I guess i'll deal with that when i get to it.

The only way I can see you doing this is with a 100mm of track increase per side

[xa-mont]

i don't get what you're saying?

[Sam_Q]

to have the right geometry with an s13 crossmember you need to run their struts as well, however to do so you need to sit the struts at the same distance from the crossmember as they originally where on the s13 or else you will have positive camber. This means to do it by that method you need to make your car the same width as an s13

[xa-mont]

I'll be running and entire S13 front end. With the use of different offset rims i should be able to scrape back the track enough to make tyres fit, In a standard S13 setup i would end up with a ton of camber, but i will run camber tops and possibly coilovers with camber adjustment at the bottom as well to try and get that back to a usable point.

if you find a match for the ta22 please let me know as i want a rack an pinon setup with my ta22 3sge beems 6 speed

[Sam_Q]

Even with those camber adjustments the track would be massive using S13 gear. I can't see any way it could be made to fit nicely without serious work.

Yeah it would be a pity to lose or cut up that lovely standard set of extractors, just to accomodate the idler arm.

cheers Chuck.

I have changed my mind about something, I was going to stop offering this conversion however I will continue to do so but only the crossmember. I am thinking of showing a guide on how I combine a corolla and celica steering column into one.

So alexlegault if you want a converted crossmember without engine mounts then I can convert one for you.

Dropped my AE71 rack off to the engineers to get shortened yesterday Had a look at an AE82 rack at the wreckers to see if I could use it - rough measurement gave me 550-560mm inner tie-rod to inner tie-rod. Measurement on the AE71 rack was 580mm. Calculation I came up with for the rack length needed in the TA22 was ~510mm. Ideally, the AE82 rack would need shortening too so I stuck with the AE71 rack.

The mounts on the AE71 xmember will be easier to mount to the TA22 crossmember too, as the AE82 rack is mounted on the firewall... All this talk of a parallelogram with LCAs and tie-rods. AE82 has nothing of the sort in its geometry. Had a quick look into Camira racks, but they are over 4 L2L, so it's not much quicker than TA22 recirculating ball steering.

Hopefully I don't run into any issues with the pinion housing being too far inboard & fouling engine bits.. I have a spare xmember and 3T so I'm thinking about dummy fitting them to make sure there are no problemos.

Oh, and frankensteining a TA22 steering column with an AE71 is not as simple as it first seems. So far ideas involve a welding spigot on the end of the TA22 column housing to accommodate the AE71 bearing, with an extra thrust plate on the firewall side to locate it.

Once I get the rack back, I'll post some pics up of progress so far.

Cheers, Jess

adapting the two steering columns isn't hard. I should be doing this in a few weeks and I will show the steps on how to do it.

[stidnam]

yeah just remove the bearing from the ae71/ke70 lower shaft and make a bushing to support the shaft that presses into the ta22 column surround.

[jb_22]

Exactly my plan good Sir Only my plan is to keep that bearing, and make a spigot for it on the bottom of the TA22 column housing

[stidnam]

not sure what you are referring to by spigot as that is a tap?. The bearing is larger than the ta22 column housing so it wont fit unless you cut and weld. If you press in a bushing my hot tip is to make the centre hole slightly undersize and ream it out to size once pressed in as it distorts slightly and can bind in one spot and cause uneven wear in the bushing.

[stidnam]

May run into issues with rack housing hitting the block. Here is a ke70 rack & crossmember shortened to give no bumpsteer to give you an idea of where the pinion and housing sits.

[Sam_Q]

stidnam- your work so far looks good, I am curious though why you didn't fit a ke70 crossmember? would it of not been easier?
