b18c1 swap

What would be the pros and cons of using a jdm ys1 or s1 tranny (both with lsd) with a b18c1 swap(did the b18c1 come with an optional lsd?)? Could these trannies even handle the extra horsepower and torque of the bigger engine? Also would I run into fewer problems using an obd1 engine as opposed to an obd2? TIA.
