Gear Ratios

Post by DragonCypher »

Can anyone give me the ratio's of a 4spd borg warner box off a 2L GE Sigma?
Didn't grab the speedo cable so I'm thinking I can judge speed by rpm instead :P

For anyone interested the jap 5spd from a GJ scorpion:
1st 3.369
2nd 2.035
3rd 1.360
4th 1.000
5th 0.856

Rev 3.635
'81 GJ Scorp: Donated to a mate for a 2JZ Turbo project.
'84 Honda VT250F Integra: Daily transport, mountain racer and track bitch all in one.. damn slow in a straight line though
Future Project (on hold until I move to Melbourne in July): 2.6L Wideblock Astron 2 - Eaton M90 supercharger, draw through 45DCOE Weber.

If your looking for some good drag racing calculators this site's good.

http://www.golenengineservice.com/html/calculators.html

For you cobwbs, just measure your tire height. If we say 26.5 inches (probably smaller than that) your doing about 124mph, which is good for about 10.9's going off the calculators.

Cheers
Simon
