T18's

[ae86 slide]

i know there is a difference in t18's between the ones with factory sway bars and the ones with out.
can any one tell me which has the 3.9 ratio and which has the 4.1?
cheers jase

someone please help!

mine had no sway bars an pulled a 3.7 out of it centre was factory, you can get a ra40 centre to bolt in with 4.1 for max. $100 from wreckers. Its hard enough finding t18s, let alone holding out for a 4.1

[darkon]

get the ra40 automatic centre its got a higher ratio then the manual one

[Bustin_86]

can some one please include a index of sorts of diff ratio's? as in, what kind of ratio will favour top speed and which one would favour acceleration... Beause i get very confused lol. Also, what ratio is a stock S series out of a ADM sprinter?

[riceburner]

Stock ADM s-series is 3.9

Lower the number higher the top speed.

So a 4.1 center would accel a little better and be more responsive then a 3.7

t18 - 3.7 and 3.9
ra40, ta22 - 4.1

check the build plate to confirm

cheers fella's!

no t18 ever came with a 4.1 from factory to my knowlege

so ra40 or ta22 ring and pinion gears hey, the hunt begins.
is this true about the auto having a higher ratio?
