Has anyone ever put a TDI in their NBC?
Actually this may work better than you think. I'm pretty sure the 98 TDI does not have an immobilizer, so you don't have to worry with that. The wiring will be slightly different and you will want the TDI cluster as it is different. Also, the TDI transmission has different ratios, so plan on swapping it along with the engine. Keep the shifter & linkage from the 03 as it is way better than the 98. I would recommend an Audi TT short shifter while you are doing everything else.I have a 1998 NB TDI with the ALH motor and I have a 2003 NBC with the 2.Slow, (both manual trans). The NBC motor is getting tired and blowing a little smoke So I'm thinking of swapping the ALH from my "winter beater" over to the NBC. Since I have 2 complete driving vehicles technically I have everything needed for the swap.
