I, too, just stepped into this thread. I wish I would have seen this sooner. You are incorrect about the engines, though. The '96-'04 Acura RL motor is not sideways. Seeing as I had one sitting in my garage as well as a AR5 tranny, had I seen this, I would have been able to give some better feedback. I was motor swapping a 3.5 into my Acura Legend coupe, (which is becoming more commonplace nowadays), and was about 75% done w/a (anticiapted) 500hp Rotrex-s/c build until I purchased an M3 and parted the Legend.
