Got a question..i've got a guy who wants to go with ITB's on a H23 non vtec...i dont know too much about ITB's but you dont need a intake for filter correct? Since each cylinder has it's own throttle body...and we're planning to space it so we can use the stock fuel rail and fuel injectors..but it should be a direct bolt on..plug and play? I've also heard that you should have built motors to run the ITB, but then again i also heard that it's fine if the motor is stock also..either way gotta get it tuned and they should be fine..correct? are there anything else i may need to get in order to run and install the ITB or just the ITB?
