need to get the vtr ecu, key, barrel, transponder, engine and loom
if u use the 1.1 gearbox it will have quicker 0-60 times and be quicker off the mark too as it has closer ratio's than the vtr box
the loom will need to be spliced in i think on a few wires but not alot, not sire if ud need the vtr fuel pump too and also the clock may help
also would be a good idea upgrading brakes and that if u get a vtr donor car to get the enigne from then u could use the rear axle too
probly missed summat but thats a start for u
