I am looking at fitting the BEX turbo to my B5 1.8T. I have the Neuspeed Xtreme TIP (some pics here https://www.audi-sport.net/xf/threads/neuspeed-xtreme-turbo-intake-pipe.16965/) However the BEX compressor inlet (K03-73) looks to be a tiny but bigger than the K03-005 so the adaptor plate doesnt seem to fit. It was snug on the K03-005 and the K04-15 I had fitted years ago but went on. I measured the inlet and it 45mm on the BEX K03-73 and 44mm on the K03-005. The other thing is the adaptor retaining holes that bolt the adaptor are lightly further out on the BEX K03-73 than on the K04-15 and K03-005. I am thinking of getting either just a new silicone TIP or getting the adaptor machined slightly so I can fit it. Anyone else had any issues? I guess the BEX turbo is quite uncommon.
