Hz running gear

Hi everyone. I've got a hz ute with a 202 in it. If I put a Aussie 4 speed in it should I put a 3.08 ratio salisbury diff in it or keep the original diff? Cheers brad

WHAT? no gravy?

At the moment the 3 speed manual. I'm just sick on the column stick hitting me knee all the time. And a banjo diff or something like that? I've heard that the aussie 4 speed will be good with a 3.08 Salisbury. Obviously with a 202.

Well I'm not sure about the old banjo diff but its just the regular one that all the 202s had behind them. But the bigger diff is defiantly a 3.08 Salisbury. Do u think if I put the salisbury in it and the 4 speed will it go better?

std 202 with a 3.08 will struggle a bit. while the 4 speed will help get it moving, you will be left with poor top gear performance.

a blue 202 might cope.

i ran a 202 in a hg ute with warm cam, ported head and better valve springs and a 2 barrel strommy and it was ok with the 3.08 diff.
fuel econ was good. 2250 rpm at 100k's

the 4 speed was a 1 tonner box with 3 low gears and then top. (m23?) cant remember the nos.

is your salibury a 6 cyl or v8?? as the tail shaft yokes are different (you cant just swap em over either!) it would be easier to change out the banjo you have to test the ratio change before c/o the diff housing.

A 3.36 banjo would be the smartest move and will give you 2450 rpm at 100k and some respectable acceleration in top gear.

After 4 years ... it runs..Yeah!

Providing it's in good condition, the Salisbury will be perfect for your ute. The original Banjo would be 3.55 or 3.36. Providing you're not towing huge loads up steep hills regularly, the 3.08 ratio will give better mileage, less engine wear, and still be quick off the mark. You will need a V8 tailshaft to suit, but it will all bolt in, and will be there waiting if you do decide to fit a V8 later on!

That's true, what's the part Called which goes into the gearbox on the tail shaft?and can you change it? Ive got a fairly large V8 tail shaft but the part that goes into to gearbox is larger, so it wont fit into the aussie 4 speed.otherwise I guess I just need to find a regular V8 shaft?

Holdenpaedia, they're the brakes Mate.

My Salisbury is one for a V8, and I realized that where the uni's sit it was about 5mm wider.

To the 4 speed? Or can I change where the tailshaft bolts onto the diff?if not where do I go ?

The output shafts on all the Aussie 4-speeds (6 and V8) are the same, so if your tailshaft yolk is too big for the gearbox, it may be from a Saginaw or Muncie, or possibly a Chev auto box. If that's the case, your V8 tailshaft may be the wrong length. I'd hang onto it, and get a shaft, with yolk, that came from a HQ-HZ with an Aussie 4-speed and Salisbury diff - then you will still have the other shaft and yolk if you change to a Chev later on!

If you want to connect a V8 tailshaft to a 1-tonner diff, you can get a "crossover" uni-joint, from "Hardy-Spicer" that will do so. Another (more expensive) option is to have a 1-tonner tailshaft shortened (and balanced) to suit.

Did this exact conversion last year. No one could give me any info on the above mentioned uni though. Ended up just changing the diff yolk and fitted a V8 Tailshaft. All good now. Also mine is a 3.08 ratio behind a little 2.8 litre blue 6 pot. Also had it behind a red 202 and it was great.
Fair enough it is slightly slugish off the mark but by the time ya pull 2nd its doin like 50-ish and passing those tools that try to beat ya off the lights.

I find it better than the celica 5 speeds as the old aussie box has a better ratio spread. I also get up to 600kms to 1 tank of juice highway driving so its not bogging the motor down in any way.
