If I come across anymore 3.7 ratios I will get in touch
I know that either Ratio makes a world of difference
Getting harder to find👍

let me know if you ever want to sell the 3.7:1
Cheers dp

What sort of leverage ($) would it take to get that 3.45? it'd go nicely with an L20B & a slippery diff in a Sunny sedan. Is it a ring & pinion or a complete centre. The slipper is wearing a 3.7 ratio at the moment.

I have a 3.45 in my stash in case I went ca20de
in my 1000 but ended going H190 lsd

I had 2 3.7 H165 diff centres
I had to hunt hi and low and got them
But the last 3 I have got were all 3.9
So I sold one 3.7 and have one left
for myself.
I think only the series 1&2 auto bluebirds
have them

No 3:7 ???

Hi All

There are no chipped teeth or hardening deformation
They are free from contaminants
They are a cheaper alternative to a 5 speed box
