Does anyone know these measurements or know where I can get them? It would save me a lot of hassle. Also, do our cars have a manual like a Chilton or Bently manual? I used to have a MkII Jetta and the Bently manuals were like the holy grail. Thanks.
2.5" is the TB's OD, and I'm 95% sure the turbo inlet's OD is 2.25". The other 5% of uncertainty is that it's 2.5 inches . The OD of both ends of the MAF sensor is 2.75"....just in case you needed to know it as well.
