What Diff Ratio For A 20v

[chrisandliz[RL]]

hiya, boys and girls. I'm looking around for people with 20v rwd convert and what diff ratio you have.

 

I have got three "t series" diffs. one is 3.7, 3.9 and 4.1.

 

I could try each one. but I'm lazy.

 

so I would like your advice.

 

Cheers

 

Chris

 

p.s. my T18 has a 3.7 and I think it is too long. but I don't know how many of my "horses are running wild" as the motor has done 320000 km.

20V's are a high end power motor, 4.1 is ok, the others suit turbo appications. 4.3 and 4.667 are ideal for a 20V's.

go the 4.1

should give you around standard corolla feeling, with more revs.

biggo runs a 3.7 in his 20v ke70 and got 160 or 180 out of 3rd, something stupid anyway. so yes, 4.1 would be much more appreciable.

i enjoyed my 4.3 i was running with the 1ggte ke70, but alas, things must change and I'm running a 4.1 now and its a nice all round

I have the standard borgy with its 5 speed ratio, which i think is 3.89. Its ok, but its a little hard in traffic as 60 and 100 are gut less in the gears you would use at that speed, to just maintain momentum. Just a 500 rpm increase puts you into a useable area of the rev range, if you know what I mean. Its particularly evident due to the light flywheel. Anyhow, in my opinion, having not driven the 4.1 yet, the 4.1 would be a better daily driver diff. A little bonus accelleration, and ill sit a little higher rpm at the speedlimits, so ill have some ponys with less requirement for a downshift each time. Go the 4.1, trd sells 4.77s so 4.1 is quite tall for such a revvy motor, imo. How many atmo 1.6litre engines will pull 120 in second, my commodoore couldnt do that and it was 3+ litre!
