technically, an ls tranny should make the turbo spool quicker. he may have a little more lag or a harder time getting into the power band with a b16 tranny as you spend less time in each gear. i have never heard of a .80 a/r exhaust side. unless you mean an .82 a/r....which means you probably have a 60-1. if this is true, it will be a little laggy, but its hard to tell based on just the size of the housings and not knowing what turbine wheel you are running.
