235km/h sounds awesome! Erstens, did the owner post the final horse power figure and possibly the final weight? Very nice and great effort of the owner, I suppose he did the transplant himself?
I've been think adding a compact rotrex supercharger to the 1.4 petrol, but i don't have the fund as a piggy back ECU + rotrex + mounting + intercooler would run into £3k... (for ~130bhp)
But I'm still interested to see an A2 with 1.4TSI, would be ideal for power, economy and emission.
