could you put ITB's on a car with supercharger...and could such car be made street legal...and reliable for daily drive

it can be done and yes it can be made legal as long as it gets engineered and passes emissions tests. there is someone on club roadster who is going itb on an nb8a which i intend on copying and adding a manifold. there is a guy on the big forum i think who has turbo and itb.

Look at Nissan Pulsar GTi-Rs and GTRs for ITBs and turbos. Once the power level goes up, they ditch the ITBs as they cause too much restriction.

if you where running 50's total area would be 628sqmm. stock throttle body has an area of about 173sqmm. i spose the restrictive part would be the inlet to the manifold then. so if you have an 80mm inlet its then 251sqmm. do the gtirs have a small inlet to the manifold or something? that would be the main restriction i would have thought.
