I am thinking of replacing the 16v in the Jetta at some point and want to use this as a way to list all the shit that is needed in one place for the conversion.

Please feel free to add to the list if I miss anything.

Needed parts,
  • Engine
    • Gasket kit at the very least
      New Oil pump
      New chains and water pump
      Any new Parts needed to replace old crusty shit
  • O2A or O2J gearbox
  • High pressure fuel lines
  • Exhaust Manifold (6branch?) or adapt the R32 exhaust mani to fit the current system with new downpipe section
  • Exhaust? Current 2.5inch with two box system enough?
Anything that I am missing?
