02R gearbox fits you just have to shave the mounting lugs as there is webbing between them to fit the gearbox mount. Some ratios here: https://workshop-manuals.com/seat/leon-mk1/02r_5-speed/technical_data/gearbox_identification/code_letters_assembly_allocation_ratios_capacities/ VNT needs suitable n75 and mapping. He needs bigger injectors right off the bat if he wants to do this. Also the 4 pot flywheel wont be offset balanced to the 3 pot piston / crank assembly so either get that done somehow, or get the 3 pot flywheel machined and re pinned for 4 pot clutches or else just live with the vibration.

Have you hooked the end of the column into item 9?
