u will need a donor turbo car, 220 or 620 etc or atleast the complete engine, box, loom.......... then u will need a donor 96 onwards rover 420 bubble for the engine mounts, pas pipes and coolant pipes etc also u may need to sent the ecu away to get decoded depending on what one it is? then the loom. i had my 1.6 out and the t16 in in a morrning but the wiring was not so simple! not sure bout the climate but if you want to keep a/c u will need to make sure the doner 420 has it so u can use the pipe work and compressor if the turbo lump dont!
