Ta22 Diff Into Ke25

[brendan]

hey all

i have just purchased a ta22 diff would i be able to bolt it straight in my ke25 and still use the standard master cylinder for the brakes?

cheers brendan

For a start it won't bolt straight into your 25. You wll need to cut the TA spring mounts off, and weld leaf spring mounts on. The diff will be wider than your original one, so you'll at the very minimum required wheels with offsets the put the wheels inside the guards more. Don't know about tailshaft. Master should be fine, but any master other than the original would be better than the one you have.

ahhk cheers mate...thanks for the info

hmmm now the second thoughts are kicking in....lol

[oh what a nissan feeling!]

not a good idea, the appox widths are 1370mm vs 1295mm,

 

and to make it worse, the rear of ke25s are already more of a fwd offset.

yeah thats right,

 

ke20/25 wheels are 12x4 and +30p and tyres are 155/70?/12

ke20/25 = 1320mm wheel mounting face to wheel mounting face

ta22 = 1355mm wheel mounting face to wheel mounting face

ke30/55 = 1355mm wheel mounting face to wheel mounting face

 

the top of the ke25 rear arch to the top of the other rear arch on the other side

is approx 1500mm, including the thickness of the lip and a few mm clearance you will need,

so your combination has to fit inside that.

 

185's on a 5.5 or 6 inch rim at +30p with a ta22 diff would work and the wheels should clear

the front struts as well.

 

width of combination in mm =

width of diff wheel mounting face to wheel mounting face

+ width of tyre / 2 * 2 tyres (ends up being width of 1 tyre)

- offset * 2 (applies to positive offset)

 

so eg a ta22 diff with 14x6 +30p and 185's = 1355mm + 185 - (30x2)

= 1480mm

 

ke20/25 = 1500mm avaliable - 1480mm combination

= 20mm total clearance

= 10mm a side ( 20mm / 2 sides)

 

so if you fold the lip up and it takes up 5 mm and then you will have 5mm

clearance for when the diff goes straight up into the body with both wheels

eg like a speed bump.

 

replace rear bushes also to add stiffness and stop excess play.

good info, anybody able to tell me how strong a TA22 diff is?

Do we know the face to face width of a TE27 diff?

 

I might ask the question on 3TC forums

[styler]

yeah been meaning to find it out a te27 diff width, its a lot wider but the wheels are very positive offset and narrow from factory, they

just get under the body, apparently the body is flared outwards from factory and a flare fitted over it, same with the fronts.

you could work it out, te27 rear track at is very wide at 1295mm compared to the front at 1270mm and wheel offset is about +30p.

so diff width (wheel mounting face to wheel mounting face) = track + ( offset x 2 )

= 1295 + 30 + 30

= 1355mm.

 

so same width as a ta22 if not the same diff :) well apparently its a corona diff though but could be modified.

 

but you can't fit wider tyres or lower offset rims unless you modify the wheel arches

- rework the rear wheel arch (difficult) and cut out the fronts (easy).

 

not to say people don't do it, just google image te27 and look at some of those wheels!

but the suspension must be rock hard as travel could only be an inch on some of those cars,

i wouldnt recommend it personally but some people do hack up the arches or just have no

suspension travel which isnt as good for handling or comfort.

I'm using a TA diff with flares (and the required body work to suit) with RT142 snowflake mags. Fits very nicely, but would have issues without the flares.

[styler]

yeah those snowflake rims are 14x5.5 and 114.3x4 pcd redwarf? any idea on offset?

i think snowflakes come on coronas, taragos, import ae86's and maybe a few other cars?

[Redwarf]

They'd be the puppies. 4x114.3. Not sure of the offset.

 

*Edit*: going by the markings, I'd say they're +27.
