You can.... But why?

The FIAV depends on the coolant flowing through the TB ports.

if you only loop the TB lines, youll probably have issues with idle if the temp fluctuates enough. a full FIAV delete is best in this case.

you can loop the turbo coolant lines, but a full delete with proper fittings/plugs would be more sensible if you are eliminating the coolant flow.

why are you deleting them anyway? coolant flow for the turbo is a nice thing to have for a street car, and if it not broken, why change it? in warmer climates the FIAV delete i common without detriment, and eliminates a frustration point, though i still have mine cuz it gets cold up here and my car wont cold idle for beans below 50*.

Like said, if you loop the lines on the throttle body your car will idle around 2000 rpm or more and idle surge from there, you need to to a fiav delete if your going to get rid of them.
