You'll need the mount kit. You'll need an accord/prelude shifter. You'll have to cut the floorboard to run the cable shift linkage. You'll have to remove the upper tranny mount from the passenger side frame rail. You'll need a prelude intermediate shaft. You'll need 90-93 integra axles, or custom axles...I'd recommend custom...HASport sells some for the swap.

Here's a list from HASport.
