Silver03SI

I have a new si and I would like to get the same performance specs as the DC5 type Rs motor. Would it be more practical to do the full engine swap or just to do the internal work to upgrade the existing k20? What would be the likely difference in the price of the RSX type R motor and what I could get for my SI motor with 3000 miles on it? And one last qhestion, does anyone know exactly what internal upgrades would have to be made to match the Type R's engine performance?
Any help would be a great help
