Engines for MX 6 were 1988–1992 GT 2.2 L I4 1993–1997 RS 2.0 L I4 1993–1997 LS 2.5 L (2497 cc) KL-DE V6 1993–1997 LS 2.5 L (2497 cc) KL-ZE(J-Spec) V6 Engines for Millenia 1996 to 2000 were Engine 2.0L V6 2.5L 170 hp V6 2.3L 210 hp (157 kW) Miller cycle V6 And I have no clue what "Miller Cycle" means, so with that information you decide...I am not sure if headers will just swap in to the car with the 2.3 in it now

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.
