Title: 1997 mazda millenia "S" miller cycle motor
Post by: Thomas_Cronan on September 29, 2010, 03:55:59 PM
any one know about them? miller cycle motors are a five stroke motor. Miller cycle motors were made for plants and boats, in the late 90's mazda used them in the millenia. it was a v-6 2.3L supercharged 210hp motor. i just got one and it needs a bit of work but i hope the motor dont give me much trouble.  any one ever messed with one one these motors? so far only one company rebuilds the supercharger, pse superchargers.

not racing this one just a street car i picked up cheap but headgaskets are blown. (i hope) if the motor is junk as long as the supercharger is ok i can afford to fix. the supercharger is 1700 plus core!

I have a 2001 S bought new and the only problem has been under the intake manifold the vacuum plastic tees deteriorated causing a vacuum leak. Replaced them with metal tees and good as new.
