Australia ITR's final drive is 4.4 or 4.785??

[edw-R]

Can't believe. Too many ans. Hope can solve this problem soon!!

[blackdc2]

Just ask BlackDC2 I remember Jason buying a new 4.785 final drive only to find out he already had it in his car.

Regards Dyno Dave

yeah, mine was 4.7..

Heaps of people tole me that i had 4.4, then when i pulled my tranny apart, i counted up the teeth and found out they were the same, so i bought a ats 4.9

[pckit]

quick question, would an upgrade from 4.7 to 4.9 make much noticable differece?

[SKYNUTS]

Try going at 100km/h on 4th gear , wat does it read on rmp?? If it is 4.785 , it would show 4.7 at revs , i mean this is wat ppl tell me , i don know how accurate it is. Just try it , i tried it on my itr and it was 4.4 so yeah , just try it out.And yr rim size does matter.Sensors are for stock 15" rims. So if yr running 16 or a7 , it would be slightly higher.

what you were told is BS

Hmmm, I'll have to count the teeth of the one I've got sitting on the bench at work on Monday... Pretty sure it's 4.4...
I have to admit though, I've only ever swapped the final drive for a 4.9 or lower...
So, I'll double check & confirm if I'm wrong...
Cheers...

the point was how many type Rs did u have to change 1st gear to fit a 4.9?

[TODA AU]

No... Your actual words were...

but u can't fit a 4.9 FD on a 4.4 1st gear

To me says, you think it can't actually be done...

Hence, my answer saying it can be done...

You know... fact vs. fiction...



Now that's been pointed out...

You want to turn it around into a veiled point you were actually trying to make... Ok...



My first answer was simply based on looking in AUDM DC2 Type R workshop manual were it says 4.4... Further since there was doubt raise about this...

As I know I've got an AUDM DC2 Type R final drive on the bench at the workshop,

I offered to prove or disprove myself today....

See below...

Hmmm, I'll have to count the teeth of the one I've got sitting on the bench at work on Monday... Pretty sure it's 4.4...

I have to admit though; I've only ever swapped the final drive for a 4.9 or lower...

So, I'll double check & confirm if I'm wrong...

As for changing the 1st counter gear when changing a final drive,

To be honest, I think we've only done that 4, maybe 5 times...

Mind you, I've only ever changed 9 or 10 DC2 Type R final drives personally...

Of that amount, some of the gearboxes were from wreckers, both here & NZ...

Add that to final drives that have simply been sold / supplied to the customer without need or mention of the 1st counter gear...

I'd say there's more than a fair chance that you're right about the 4.7 being in the AUDM DC2R... In any case, as I said, I will confirm today...

i don't think you can use the method of 4th gear at 100km'hr method cos gear ratios in the different gearboxes are different.

counting the teeth cannot be wrong
