91 lude SI b20a5

ok ive got a 91 prelude SI b20a5 and i want to turbo it i cant seem to find a specific turbo manifold for but its a b series and with all the other b series the manifold is interchangable just wanted someone elses opinion before i buy a manifold and it doesnt fit also i want to know if the b20a5s transmission is a limited slip i dont have it on the road yet because im swaping the motor because the old one threw a rod through the block otherwise i would be able to figure it out.
