what cars or motors did these come off of which is better i traded a j1 for a y1

 

You skrewed your self. J1 is way better then Y1

check this site: http://www.ff-squad.com/Bgears.htm

 

JDM S1, J1, A1 and YS1 came on the Integra Xsi.
JDM Y1 came on the CRX SiR.

The S1, J1, A1, and YS1 all have a 4.4 FD and similar gears.
The Y1 has a 4.26 FD.

This means that the S1, J1, A1, YS1 have about 5% shorter gears than the Y1.

 

Y1/Y1 LSD trannies are crap...especially the Y1 LSD is a POS and the gears are garbage.

 

ya I've got a y1 in an 88dx and my friend has an s1 in a 91 si and he can leave me on the highway. But I plan on going turbo and the y1 will allow me to stay in the same gear longer.

 

the B16 Y1 is still better than the USDM LS tranny. I still want a JDM 4.40 FD with LSD trans.

 

J1 here Perfect. Great for cruisin, too

 

i got it for the LSD caus ei needed it is the y1 better than a hydro gsr's ratios

 

look at the post a couple of ones above yours it gives a website to look at to see every single gear ratio for the b series trannies.

Ok, now for my question, the y1 came from the crx SIr, but the j1 and s1 came from the integra's, now, the j1 and s1 have the same ratio's but what is the difference, i've heard it has to do with the year integra it came out of, but what year corresponds with the tranny code. Thanks a bunch.

y1 with lsd is working fine for me...although 5th gear cruisin sucksz

 

Yep I'm at 4k at 65mph with my S1. Highway cruising definitly sucks.

 

my s1 ownz , gas mileage sux

 

I got S1, i like it but at 50mph i'm already at 3000 rpms in 5th gear, the gas mileage sucks. But i can work anyone on the street haha!
