Si final=4.25
DX final=3.88
ZC final=3.88

Si & DX gears are identical except the final

this is why the ZC transmission with its closer gears than Si but lower final drive is the best choice when combined with Si final

It's the basic 4g tranny info

[mellowboy]

[Jos4DCivic]

Also the Si and the ZC have the bigger bearings. Than the DX

i got a new half shaft for my SI but will not go all the way in. ive tried banging the shit out of it and nuttin. but my SI has a L3 tranny. maybe this is why?

[mellowboy]

You can do it both ways.

I've never had a problem swapping input shafts from Si to DX and so forth, so i dont know the truth in this. possibly the STD and HF have smaller bearings, but Si & DX appear to be identical to me.
