    The Forge one is good...as are many of the ebay cores.

    you can fit a FMIC only...or you can run it along with the drivers side SMIC...probably depends on what you really want to achieve...if you are running very high boost on a K04, then it's possible that you *may* pop the standard ends off a standard SMIC, so perhaps doing away with it, or fitting an uprated alloy SMIC is a good idea.

    If you are running a K04 absolutely maxxed out, it's a heat pump...so you'll need as much intercooling as you can...it's easier to fit and pipe up a SMIC with a FMIC in series, than to fit a massive FMIC, and you get the same cooling.

    Or, standard are fine for standard cars at standard boost...

    Same as standards are fine for big turbo cars at sensible boost as the big turbos don't produce nearly as much heat for the same charge pressure.

    It all depends on what you want it for...

    that makes sense iv still got my ko4 and the boost is quite high. i may just get an ebay fmic the same size as the forge and keep the driver side smic then.
