QUIKXR · 09-09-2005, 12:41 AM

Does anyone know what diff gears an au2 xr8 200kw has because i always hear different ratios< ive heard 3.08, 3.22 so can someone tell me?

All AU XR8's (185/200/220kw) got 3.45 diff gears.

Thanks for that. For 3.45's they are still pretty sluggish of the line so what diff ratio would you rocomend to put in?

I would go 3.7's on the manuals and 3.9's on the autos, that gives you enough gearing for decent acceleration while still being ok on the highway.

I have an auto so if i go the 3.9's would i get a quiker 1/4mile time?

Yes you should see quicker 1/4 mile times with the 3.9's.

whats a estimated cost getting this done ? Getting 3.9's fitted that is.

Roughly $1000 mate. Looking at it myself.

Does the EECV on a automatic AU halt any gains to be made by changing to 3.9 gears? If remember correctly, Sylox said that there was not mach gained by changing to 3.9 in his automatic AU XR8 ute, as the EECV torque tags kicked in earlier or something.

In V8's it has been clearly documented so yes, your correct.... no such misfortune for the I6's

:... we'll see. Slowly but surely I'll hunt you car down on the track.... and do it on less fuel too

fuel is not the issue

: it's if you can catch me come the end of the 1/4 :eclipsee_
remind me to wear ear plugs as you'll be ringing its neck to keep up

but to be honest the 1/4 doesn't interest me at all.
