Thanks! Can you elaborate more on how you prevented over pulling?

It does not seem that additionally pushing on the pedal imparts any additional stress on the shaft........
Nonetheless, I agree with your assessment.
I basically think that the circumfrence of the SR throttle pulley is smaller than that of the KA.....
Hence, less pedal action is required to fully open the throttle.
The interesting question here would be if someone owns a JDM 240sx could measure the distance between the pedal and the floor stopper in their car. My bet is that the stopper on a JDM 240 sits closer to the pedal.

Yeah, I would also love to know this. There has got to be a few Silvia's on here that can comment, although I'm not sure how easily measured that is. I see what you're saying about the shaft and I think that is the case on the stock setup; S13 SR20 with S13 pulley, since its offset more towards the throttle body. Surely the extra moment arm of the S14 pulley has to push it past its breaking point. Also don't forget the stop isn't located on the pulley its closer to the throttle body, so the cable is actually out past that leverage point (reference the first picture in this thread). After installing the piece I ran down a couple nice roads on the way home and noticed how hard I would contact the stop under throttle modulation; its apparent its there.

I originally tried what you are describing but that factory stop is only secured with the one self tapping screw and if you remove the stop you'll see that its not as easy as it looks to mount to. You can't drill into the piece, b/c you'll fu*k up how it mounts and since its so loosely mounted I didn't feel anything I mounted to it would be reliable.
