SiR tranny vs LS tranny

How big of a difference would it make between 2 trannies on 1/4 ET?

well I believe the LS has taller gears. Most of my friends run this Tranny with there turbo set up. The SiR is the one everyone is running in the all motor setup.

I have a 91 integra All Motor. Would it make that big of a difference? Any testimonials?

SiR tranny is essential the ITR tranny w/o the LSD. The gear ratio is the same.
It will make a big difference for an LS, but if your '91 is stock or near stock, then you should ought for a GSR tranny because you will be revving very high and you won't be able to utilize the LS good mid-range fully.
