    Yes, the lighter pulley without damping should introduce a little more NVH. I can't say that I've noticed it.

    I know all the pros and cons of fitting a lightweight crankshaft pulley, and I accepted the risk. I'm not concerned.


    Simplify and add lightness.

    I figured you were quite well aware of this. I brought it up for my own curiosity, and I'm sure there are others who may not know or otherwise thought of it themselves. Sometimes choices come with unintended consequences. For example, I understand some aftermarket replacement harmonic balancers have problems with fit, or the timing mark is either off or slips out of position. Not good. The owner starts facing a host of new problems that the bad part creates. Timing isn't a problem here, thankfully.

    Thanks for your replies.

    If Daox had previous experience with no issues then I would assume it's safe to use lightweight pulleys on the Mirage.

    NST has a nice explanation at their FAQ page

    I would guess it would also fit the 1.0, but that's just a guess.

    Try looking up the Mitsubishi part number for the pulley on your engine, and compare it to the part number for the 1.2. If it's the same, you're good to go!

    Part number is the same 1104A093, but still not sure. All parts from "ENGINE - PISTON & CRANKSHAFT" have the same numbers

    If Wikipedia can be trusted on this, the only difference between the 3A90 and the 3A92 engine should be that the 3A92 has a longer stroke. 75.4mm vs 90mm. That's a difference of 15mm, which is significant.

    To get that difference in stroke, they would have had to fit a different crankshaft, possibly different connecting rods, and maybe made the block slightly taller. Otherwise, every other part on the engine should be identical. (longer timing chain if the block is taller)

    If the part numbers are the same, I'd go ahead and order a Works pulley. Worst case it doesn't fit, you can always sell it to someone here who has a 3A92.
