Hi guys just wondering if the EA's had different diff ratio to the EF's?
and do the EA gear box's have different ratio's to the EF 5 speed box's? I have an EA T5 and am thinking of using it in my EF when I convert it to manual, but I'm not sure what the ratio's are going to be like... I think I have read that the EA had a diff ratio of about 2.92:1? while the EF's had something like 3.7:1? so putting a EA 5 speed into an EF will only see ~40kmph in 1st gear or something? The EA gear box I have now is 270,000km's old but its never had any problems and is still a good box, which is another reason I want to use it because I know its in good condition and hasnt been floged. Any help/opinions would be good

Any help/opinions would be good hi the ea box has a lower 1st,2nd and a slightly lower 5th.. and the ea diff ratio was 2.92. and a std ef should be 3.08 or 3.23. only xr and ghia model had 3.45 none came out with 3.7 im running a ea box with 3.27 diff ratio and it gets 55km out of first@5500 rpm.. it will only get 40km out of first if you have 3.9 or 4.11 |

well you mean shorter..lol (the higher the number the shorter the ratio) yes. if you have a ea box fitted and you have 3.27 diff your 1st and 2nd will be aprox the same as a ef 5 speed with 3.45. same as ea box with 3.45 1st and 2nd will be like ef box with 3.77. |
