Plans for the immediate future (I'm off sick till Xmas) include oil change (fully synthetic) and genuine Renault 5 GT Turbo filter (said to offer better filtration than non turbo ones), Toad, and a look at water cooling the TB (well, they're supposed to be water heated, but you don't strictly need that for a Turbo, however, I recon it may be suffering a little on re-starts due to fuel vapourisation).
