Well I have an Auto bonnet and a spare few heads if that helps? that way you could just fix the little un which is allreaday in! I also have a spare intercooler somewhere too, the little 1.7 goes very nicelly in a 205 - Vannys right the xantia TDs can be very stodgy! seems to depend on the fuel sytem fitted with the earlier non electronic ones being rather better.
