Gear Ratios again
Shandylegs - 17/8/04 at 10:12 PM

Hi All

Recently purchased a part completed BEC (CBR1000). Having looked at the speed calc program looks like I'm in for some fun with what I think is a 3.92 diff ratio.

Can anyone give me a definitive answer if sierra diffs (Rear disk - Bolt on shafts) are available in 3.14 or 3.38 ratios.

If available what model etc.. or does anyone have one they are willing to part with?

Thanks

neither come as LSD as standard, but the vehicles you are looking for include:

2.3 diesels 3.14

2 litre petrol autos 3.38

there may be others

nearly all LSDs are 3.64. the gubbins can be swapped around between diffs though.

Not too worried about LSD at this point, just that I can get a diff without having to change the output shafts over to the push in type and I am more than willing to stand corrected but didn't think the diesels came with the rear disks.

Thanks

i wouldnt be suprised - i never saw the bit about discs! the ratios exist though.

anyone care to clarify the disks issue because i too am looking for a 3.14 / 3.38 for my CBR1000 car running disks.

Cheers

Nope, as standard you could only get 3.64 and 3.92 with lobro type output flanges.
