Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

  • Q: 16v throttle bodies

    hey guys quick question

    are all 16v throttle bodies the same diamater??

    it has confused me slightly due to the fact that some mani's are 50mm runners and some are 42mm?

    also would the audi throttle mod fit this and will it be bigger??

    The throttle body on KR motors is the same regardless of the diameter of the inlet manifold's runners.

    The 50mm manifold flows significantly better at the top end over the 42mm one.

    The 42mm is fitted to Corrados and Passats due to the better torque it produces, which helps with the extra weight of both cars.

      PM peedman about what he has. He was thinking of doing a ITB setup using 4AGE throttle bodies and (I think) has an adapter plate for it to go on a KR that he didn't end up getting (which I think is in your hands now!).

            Some guys in the US have converted and documented their 9a to digi2 by using 8v parts so that might be an option for u.

              He already has kjet, so would be a full conversion to change it....
