Hello all I am looking for info on a final drive upgrade for my d16 hydro tranny. Who makes one and where can I get more info? I searched and found a lot of info on b series and some info on a srr that wouldn't fit onto a jdm lsd equipp tranny. Any and all info would be much appreicated.
I think my stock final drive is around 4.1 I would like somewhere around 4.7

 

SRR makes one. Check it out at http://www.exospeed.com It's available for all '92-2000 SOHC Civics and comes in 4.7 or 4.9:1.

 

ATS makes a final drive for 4th gens but I dunno if they are compatible with 5th and 6th gen hydro trannys.

yep. the bolt patterns on the ring gear are different between other D trannies and the lsd equipped one. why? i dunno why they did that.

your best option is to sell that diff (not sure what it goes for), pick up a quaife and the srr 4.9. also, apparently the oe diff explodes around 130whp sometimes. if you decide to do that, double check to see if you can actually use a quaife for a normal D tranny in the one you have; as i'm not sure if you can or can not.

you have the exact same gear ratios as the ex/si. your stock final is 4.25. play around with the final drive and see if it's worth it or not. i would do it
