i know that is will bolt up, but there is this thing below the throttle body that has hoses coming from it, the z6 TB seems to have a bigger valve with the hose of some sort, while the b16 has a smaller one....just wondering will the TB from the b16 function correctly? thanks in advance.

 

here's a pic of the z6 TB:

and here's a pic of the b16 TB:

i know it will bolt up, but the valve with the two hoses on the z6 TB is different from the b16. Can anyone help me thanks.

 

fast idle thermovalve. Whether your car runs correctly or not will depend on what intake man. you are using. If it has provisions or the FITV then the car wont have a fast idle when the engine is cold. You might try using a fitv from a 90-93 teg.

 

ill be using the b16 TB on a z6 IM. thanks
