Kompressor long term reliability?
The M62 supercharger found on the 2.3L M111 engine is a non-rebuilable (debatable) sealed assembly that has no on-going maintenance requirements.
Similar Eaton units found in Ford and GM applications generally wear around the 125K-mile mark.
I do know of a few C230K owners that have had to replace the supercharger unit, and their mileages are in the 100K-mile neighbourhood.
you coul get a rebuild for roughly $500, i have seen prices for Ford or GM rebuilds for that amount. Additional port/polish or other options can inflate the price to 800-900. I would contact eaton or magnuson directly for prices/info. As far as I know all eaton superchargers are rebuidable.
