I have a 2008 yaris and i am swapping my puny TB for a larger tc TB. one problem though the tc TB has 2 extra line openings than the yaris TB. i'm fairly certain that the ones circled in yellow are lubricant inlets and outlets, not positive though. are the other 2 vacuum line hookups that i can just cap off?

any input is greatly appreciated.

What are the two threaded holes on the left of your tb for?...

Are you sure the hole in your manifold is larger than the hole in your stock TB? If not, you are most likely going to get nothing out of the swap.

And just looking at the pic, I cant remember which two are the coolant lines that run through the TB.

it holds a braket for a sensor or something like that

no i'm not sure dont really care at the moment. theres a guy in vegas who is fabricating custom intake manifolds for the yaris. and one intake manifold will work with the tc TB. and a larger TB and sweet intake manifold will mate nicely with my planned turbo project.
