the short answer is no. they can be made to fit, but the cost will far outweigh any benefits. besides, you will then have to "fool" the post cat sensors, or the car will go open loop. miller cycle has to do with the design of the engine. it is basically a small displacement, low revving, hi torque engine. it has high compression, and the compressor is needed to keep pressure in the intake, since the intake valves close late. if there was no compressor, the intake charge would be pushed back out.
