Having a 3 speed, your options aren't too great. My car's a 4 speed with a 3.08 and when I had it in limp mode (stuck in third) even then it was starting to sh!t me up the wall at 100km/h. 3:27's will still be revin pretty high, but would be the ABSOLUTE max i'd go. Anything above that would just be stupid! (no offence to anyone who's done it )
knowing sfa about diffs all i can say is that the EF one is good for everything from cruising around to flogging ricers, well it does the job for me anyway, and it will take a shift kit. Im 98% sure mine is 3.45 but I could be wrong - whatever the standard EF Futura diff is, thats what ive got and it does the job fine.
The 3 speed doesn't really give you much to play with. From memory most of the 3 speeders had 2.77 to 3.08 (My EA 3 speed fairmont Ghia had 3.08). You could probably go to 3.23, 3.45's would be a bit steep I would think but you may get away with it.
If you were thinking 5 spd, wait till after that.
I personally would get a manny over the 3spd anyday.
1st gear is way too tall, and coz it has 3 gears u get shitfull economy. (i had 1) Even put a 4spd in, as i think its not worth spending any mulla on modding the 3spd box.
The when u get the manny done, and still want more go, get 3.7s :)
