moin! have been following the theme lpg for almost a year now and in about 4-6 months I would like to buy another car. am audi fan and since the new models are almost all FSI, only older models come into question. my selection: 1. A6 4.2 4B 2. RS& 4.2 4B 3. A8 4.2 current model (at first my info was installed after still without FSI) that the normal 4.2 V8 can be easily converted, I have already read from several users here. however, you rarely find something about the RS 6. does someone have info about this? is it true that it only works up to max 50ps per cylinder? does someone know up to which year of construction the A8 (current model) were built without FSI? and when is there finally the possibility to upgrade FSI? that would be so fat! well, a dream. many thanks for your feedback LG bbc
