What is this? ive heard about them but i thought someone was b/s ing me.

 

ITB's are well....individual throttle bodies. One throttle body for each cylinder instead of the stock1 body. This pic shows itb's for the H22A. They cost lots, can only run for N/A and have good throttle response and a f***ing sweeeet sound.

I.T.B.'s

yeah it would be fun to fab some though for a b16, lol.

 

not necessarily.. you can use them on a boosted set up. i saw gary gardella's older race car with a sheetmetal intake manifold with ITB's on it.

it can be done but it wouldnt be easy.

i personally have read that ITB's are hard to tune, but i dont know from personal experience

 

ya iv seen that too, but their more of an N/A thing

 

using ITB's is kinda pointless on turbo set ups....becuase your closeing them off from the outside air...if you know what i mean...and i have also heard that they are pretty hard to tune...i think thats because you have to tune the Air/Fuel ratio for each body not just one.
