for a b16a1 swap which tranny is the best? let me know if i am wrong with my info!!!

the Y1 came in the jdm crx and has the option of the LSD.
the S1 came in the usdm 90-93 integra, no LSD.
the S1or J1 came in the jdm integra, no LSD.

when i run each tranny threw a drag simulator they all seem to have close 1320 times (within 0.04 sec). which tranny is the most reliable...what would you recommend? is the LSD worth the extra money?

 

Dont get the LS tranny. Yes LSD is worth the extra money.

 

if you can get the LSD go for it . dont get the LS unless you plan to go F/I . if your going all motor dont get LS tranny.

 

I like my jdm J1 trans...even though it doesn't have an LSD the gear ratios are closer than the Y1. It is great for accel. but it is a bit annoying for highway driving. If you want the best of both worlds try to locate a YS1 with an LSD. Hard to find because they are around in less quantities than the others but will be well worth the effort.
