you have a b-series motor, and most b-series motors should fit your tranny, HOWEVER, the 3rd gen lude is extremely limited in terms of swap availability. do some searching, this has been covered before. i posted a few questions about a year ago when wrecked my gsr and i wanted to drop the motor in a 3rd gen. what i came up with is that it's nowhere near worth the cost or trouble. your bet bet for a motor swap is an h22, but that's not worth it for that old a car either, IMO.

not trying to be a dick or burst your bubble, just trying to pass on what i've learned.
