I hear ya though on these new gearboxes they are brilliant, the one in my rs6 is a tough old thing, not as quick but still quick and very tough keeps taking over 700 lbft up it's arse lol

But it's the having an os giken 88 sequential in it that draws me to the car, like rods car I used to lust for that spec, and with skylines I wanted a sequential and to flatshift drag racing, and I've never had a twin top mount set up either, so much easier to work on than the low mounts
The entire shift time will not be 50ms though. Same with a mates sequential....yes the actual movement of the drum might take 50ms, the movement of the shift fork. But in order to achieve that, power must be cut first, and then re-applied. The entire time IS longer.

So saying that "50ms", isnt really telling the true picture. I could easily say my mates Samsonas only takes 40ms in some cases....but the reality is an actual shift takes longer.

With the GTR, it really wouldnt matter if the physical shift time took 50, or even 200ms....because that isnt what's happening when you feel it change gear. The actual gear selection has already taken place much earlier, when it comes to the driver requesting a "shift"....it just transfers clutch from one set of gears to the other. And as soon as that's done, the next physical gear is selected in readiness for your next request some time later.

And as I said to my mate with the R33. Having experienced both dog boxes and sequentials. Not a chance would I ever want one for a road driven car. Some aspects have appeal....many more dont though.
