First difference I noticed is that there are 2 pulleys for the S2000, and no pulleys at all for the NSX! in fact the cable is doing a complete U-turn of 180║ in the NSX with no pulley!
, and in the S2000 the cable is doing only 90 or 120║ turn but uses a pulley!
So I decided to start my work there, so I took the pulley out of the S2000 and fit it in the NSX regulator, here's how I did it!
The pulley is somehow fixed to the regulator by pressure, the only way I thought I could fit it back somewhere else was to drill a hole in it, and fixed it with a screw passing through and a nut in the other side, so this is exactly what I did.
Fist step: drill a hole in prior to remove it.
