I was just comparing the KKK K03 that is on my A3 1.9tdi engine vs a KKK K03 that came off of a passat 1.8T and I noticed that the compressor side of the passat K03 is noticeably bigger. Is it worth swapping out the tdi compressor for the gas compressor/housing? The turbine side looks the same to the naked eye. I haven't disassembled them yet. Also is it a could idea to swap out bearing housings. The gas version is also water cooled for extra protection. I would just swap out the turbine housing sections if the turbines are the same and bam more boost.
