Replied to your pm. There are no updates to the evaporator if it's the same size. You can "update or upgrade" the poa and expansion valve setup by using a poa delete kit which most guys don't like or using an accumulator/orifice tube setup. Either way you may want to consider upgrading the steel a6 compressor to either a Sanden type or aluminium a6 replacement as those compressors are designed to cycle and they don't have the oil slinging issue that comes with the majority of steel a6 compressors.
