then a stock motor with a jackson racing super charger would be the way I'd go. I would use a motor that has good hp numbers stock, so that you have a good base to start with. the h22a as mentioned above may be a more compatible swap (less fabrication) than the b series motors, and it has awsome hp to start with ( hell after putting it in you may not want to add more) figure 220hp from a stock h22. I don't have alot of experience with the h series but I have been told they are extreemly reluctant to cooperate with forced induction.

the k-series also has the multiplexed system, basically more than one signal for the ecu on just one wire, so it is picky when it comes to tuning; however hondata ( and I am sure uberdata) have systems for the k-series so that should eliminate those problems.

my favorite is still the b-series, b16, b18 ( not a huge fan of the b20, to see if the shifter issue is a problem you'd have to look at the rod shifter ( on a stock honda) and then look at the tunnel in your car where the exhaust pipe runs. If I remember right when I put on my cat back the tunnel would be in almost the perfect spot, the only question would be bolting on the rod supports and then the hole needed for the shifter. also check hasport for motor mounts for the swap ( regardless of what engine you decide on).
