ornas,
I am using some Triumph Daytona 675 throttle bodies (about 2005 model) for a non-turbo 3.6 engine I am working on.
They are 44mm ID at the throttle plate and come in sets of three. They can be separated and spaced further apart, but I decided to keep them together to keep the linkages simple and to suit the same size filter that is used for triple Webers.
The throttle bodies have ports for fuel injectors but I am going to plug these ports and fit my injectors lower down in the intake runners I fabricated.
For a turbo application, obviously you would have to make up some intake plenums, but the rest of the setup could be similar.
I bought these on eBay for $125 each.
