5 speeds have overdrive 5th. The ratios aren't any closer.

 

Get a lower diff ratio. ie. if you already have say a 4.11, fit a 4.3.

ahk kool cheers buddy

Felix beat me to it. Yeah consider a K50 just to have an overdrive.

The ratios are different, but only slightly. So much so you'd hardly notice the difference.

Actual ratios can be found here...

;)

put a sticker on the back window that says "this car has a rotary in it" and just stare blankly at people when they ask you about it

if you put a cam in it and get it all built and tuned right you will need a shorter (higher number) diff, eg a 4.3, or maybe even higher ratio again (but that gets complicated finding the bits and fitting them).

 

if you have a 4.3 or shorter and a loud exhaust then highway speeds get somewhat deafening. A five speed will improve this slightly by about 500rpm, but the best solution is for a quieter exhaust or a larger engine and taller diff.

 

Thats your choices there :)

i don't c the reason for a 5spd now not if it only 500rpm difference will just fill my exhaust with hotdogs with a 286 bdure cam should still get a fer lumpy idle
