Hilux 4x4 Forum

Hi,
I have a 1992 Hilux 2.2, 4Y, 4x4
I would like to put in a 2001 2.7 (3RZ) Rear diff with diff lock into the 4 Y.
Is this doable?
Is the Ratio the same?
Are they the same Width?
The 4Y has the SA made Diff in.

I would not put 3RZ IN by all accounts it is fuel thief and the 4 liter V6 a better option.Would do WL Mazda or Beams Toyota motor.Run Kzte on standard diff(petrol) and speed long road 100km true speed and not bad.

He wants to fit the diff, not the engine

Do you have the diff already?

If you have a local gearmax diff on your SFA already, I would rather take it to a gearmax agent, and have a diff lock fitted to your current diff.

Ratio on the 2.2 is 4.88:1

I dont think the 3rx ratio is the same

Thanks .
I actually would like to use the other Diff, as the SA Diff is already the third I put in. The housing etc. does not last. I must have been one of the first unfortunate ones, not to get the imported one. They are indestructible. I will try and find out the 3RZ ratio.

3RZ diff ratio is 4.55:1.

Thanks guys for the info.
Appreciate it very much.
Unfortunately, the 2.7 Axle is wider than the on in the 2.2
Are the Import Diffs for the 4Y still available?

I Edited my post. the Sfa diff was 4.88

Dieter have a look on facebook under:

HILUX SFA LEGENDS and

HILUX SFA.CO.ZA

May be somebody will be able to assist you with an import diff.They become very scary now.

you can also try N1 4x4 or Barrie from Ultimate 4x4 spares they may have

Thanks to you all for the info.
