Diff Gears What ratio

[the_duke]

Hey All.

I have a Vs V6 ute Getrag Manual.
CIA,
69mm T/B,
1.97 roller rockers,
18inch "02 Monaro wheels


Looking for some Diff gears for this guy on ebay.

Pretty good price i was thinking.
Commodore / Ford 3.45 (3.5) Borg-Warner Diff Gears V8 - eBay Axle Parts, Transmission, Car Parts, Accessories, Cars, Bikes, Boats. (end time 12-Mar-09 13:02:40 AEDST)

My questions are?

How can i tell what gears are in it?
What would you recomend? please comment and choose on the poll?
What RPM would i get when traveling at 100? With gearing 3.45, 3.5, 3.7 (is there a calculator on the net somewhere?)

What good places in Easturn Suburb of Melbourne are there to install them?
What price am i looking at to get installed?

Thanks guys

Ive heard 3.7s are probably the best compromise and if you have a 5 speed you wont notice it as much of course compared to a 4spd auto.

Cost should be a few hundred bucks. Ive read about 6 speed owners of new commodores having 4.11 and not really noticing it

Remember your speedo will be out and will need to recaliberate it if you change

i have 3.7s in my VR 5 speed.. increase in torque is very noticable... i installed an lsd as well at the same time and its great..
i havent driven at 100km/h since i calibrated my speedo but i'd say its aroun 2400rpm

Yeah yeah definatly 3.7's. I have run 3.08 to 3.45 and then a set of 3.7 gears and have never been happier. I mate has 3.9's in his Vs and it makes
1st and 2nd gears not real user freindly (too short) 3.45's are good if you have power.
