ceaser, like i told, i never ever done this on a lupo but i know how to do it, u just need to find a junkyard with nice parts
U can use gearbox from a seat ibiza 1.4 tdi/audi a2 1.4tdi/seat arosa 1.4 tdi, transmissions from an arosa or lupo 1.4 tdi, gearbox shifter and cables from a 1.4 tdi, pedals and clutch pump from those cars again, and some bits, the bets way to do it its buying a full and wrecked 1.4tdi on a junkyard
