Manual R34 Gtt Diff Into R34 Gtv

[Bayside Blue R34 GTV]

im thinking of fitting a gtt diff 4.11 ratio into my gtv which is 4.36 at the moment. will it be bolt on or?

It should do. although you need to make sure that all the flanges match. The GTT driveshafts are 5 bolt. I don't know about the GTV ones, but there are also 6 bolt (GTR) flanges and 6 bolt (which is really 3 pairs, as used on S chassis cars) and it is remotely possible that Nissan were licking cane toads when making the GTVs and used one of the other flange types. More likely that they just used the normal 5 bolt though.

Tailshaft flange should be the same. They'd need serious toad usage to change that.

The diff housing should just bolt up - they're all just R200 housings bolting to the same sort of subframe.

Should bolt straight up. GTt and GTv are the same.

Essentially a GTv is a non-turbo GTt.

On a side note:

If you change your diff ratio you might need to reconfigure your speedo.

The ABS (3 channel) system "might" need tweaking too as the ABS sensor monitors the speed of the each front wheel and the rear drive shaft, the system "could" potentially crap itself when ABS is kicks in, due to mismatch in sensor readings.

ABS does not need tweaking,

as long as the diff has the ABS sensor on the front side of the diff then you are sweet should bolt in straight up and off you go provided the halfshafts match the driveshafts on the car.

i went from a 4.11 diff to a 4.36, did not notice any change in speed however when in 5th gear, doing 100km it would sit higher revs (3200rpm or so compared to around 3000rpm or under with the old diff)

Um, I have an R34 diff in the shed that has the ABS sensors on the half shaft stubs. Just like this Are you guys sure that your R34 diffs have just one channel for the rear?

I was refering to actual road speed. ie. if your your speedo reads 100km/h, is your car's speed relative to the ground 100km/h.
