I have a y1 cable tranny on my b16a (out of a 90-91 JDM Integra, non LSD). I'm running 10 inch rims and tires (no exception here) , I'm desperate to find a way to drop my final drive ratio to around 3.700 , my current ratio in the y1 is 4.266 , 6500 rpm at around 60 won't work for me.. I know everyone wants to go in the other direction so I'm wondering where to start. Will a a final drive gear set from a sohc civic work in a b16 block w/ a y1 tranny, the ex is near 3.700.. I would appreciate any help from you guys, this will be a sick swap when finished, this is only one of many hurdles to come...Thanks

 

quaife sells a 3.786, although i think you'll need to upgrade to a ys1 transmission

(92-93 jdm integra b16a cable / 92-93 us integra b17a cable)

be careful, 92-93 b18a trans are also ys1

 

A 4.266 fd is not gonna be 6500rpm at 60. I'm also pretty sure a civic ex tranny fd isn't going to fit into a y1 transmission. But hey you never know...

you're right on both parts.
