If you are talking about the F22a1, it has cast iron sleeves. If you are talking about the F22B, I'm not sure. I'm sure it packs whatever a USDM H23 does.

The only motors that use FRM are the H-series, C32, F20/22c.

What does the F22B sport, then?

If we want to nitpick the B21 was also FRM.

The rule of thumb is F-series = iron, H-series = FRM. This does not include the F20C/22C which are also 87mm bore, FRM.
