Gearbox issues

[2LV8ETR]

Greetz guys, I have a couple of issues with a manual conversion I just performed. The vehicle is an R32 GTS-t.

I replaced the auto box with an R33 Nismo 5-speed close ratio box with a 2-ton clutch and ceramic 9 puck plate. The three main problems are as follows:

1: Whenever I change into any gear above 2500-3000 rpm it crunches into gear, below these revs and she swaps smoothly.

2: If I'm stationary or moving, in or out of gear, and punch the clutch with approx 4000+ rpm, the box starts grinding continuously until I pump the clutch a few times and then it ceases.

3: The speed sensor in the box is an electronic pulse type, the R32 is a cable driven sensor. What are my options available so I can have my speedometer back?

Any help would be greatly appreciated.

Get an R32 gtr box speedo drive take the gear of the bottonof the shaft and replace it with the drive gear of the bottom of the electronic unit from the R33 box there is a more detailed description done by clint32 in these forums i myself have the r33 box in my 32 but u just used the vl turbo speedo drive then had it recalabratied but both of these work
