errr, thanks Guys... I think
the exhaust - well it lasted about 2 weeks then I sold it - it was just insanely loud
despite the fact I hate loud exhausts, I was somehow persuaded that I would need to fit a " performance " exhaust to get the best out of the conversion
yes. the supercharger had it's own oil supply / cooler / filter, and once the standard exhaust system was back on, you could hear the really addictive whining sound it made after 3000rpm
the Xsara VTS is near enough mechanically identical tho the 306 gti6 guys - same engine, chassis, suspension, brakes etc etc etc
