In the 93.5 supplement book, it says that a modification has been made.

The valve timing and the valve lift have been altered (For A/T models)

So i'm assuming that this is the change of intake cams that the 91 had?

Whats wierd is that it is ONLY for A/T models...

And also that might make sense as redline for A/T models is 7250 and M/T it is 7500.

What does everyone make of this?

Infiniti tells me that book isn't always right... some 93.5's have the new tranny, while other's do not.... It may even be possible that some 94's don't have the new tranny but I doubt it... I think 93.5 is the only 'ha;f' year for the g20.. with questionable as to what mods it really had.

That answer a lot of questions as to why there's such a vast difference in performance between the AT and MT. Now I NEED to get me that intake '91 intake cam.

Don't know about all of that but the redline bit is true.
