when i was building my 02 WV Golf TDI, i found a junkyard in The Netherlands (yes, in Europe) that was really good. it was cheaper for me to buy a complete 5spd transmission swap kit from him and ship it over-seas than buy anything local. i also ended up buying a complete custom tuned ECU shipped cheaper than anyone in the US would tune mine. had him send me the bigger AFN injectors with it. just his tune and injectors made that car super fun.
