I used the subframe off the Ibiza and welded it Upto the polo as the Ibiza Cupra uses same subframe as the mk3 golf, also the gearbox mount was just made up from a 6n mount and Cupra mount, I did start a thread on here building it then got it running 212bhp drove it for a while and stripped it for another project also instead of cutting the wiring up I put the Cupra dash in the polo and the full loom and just wired it into the light switches etc so much easier then bodging a loom
