The Import Racer article how to is sooo vague and is chock full of inaccuracies. use heavy Throttle webste as a guide and call them for any questions. They are a great help, even for me with a Kouki 180sx blacktop (slightly different wiring, sensors, ecu, etc..).
Anyway, use the HICAS rack. It has a higher ratio (quicker turning) than the non-hicas. So consider yourself lucky to have stumbled upon such a thing in your clip.
