yea the k20a is the new honda integra type r engine. the good thing about the new k series engines is they are mounted like your d16y8, backwards with the intake manifold on the front. They also come with a 6speed, and 220hp. very very nice motors.
HAsport sells a kit to put k20's in cars originally equipped with d16's, so I'm sure it wouldn't be too hard to put it in there instead of your d16y8.
