Hi I am from Holland
And sorry about my english thats why i am posting more pics then words:icon_razz
I hope we will understand each other I have an RSP Mk3 with an 1.5 JZ 6 speed single Turbo etc etc didi the swap myself
And yes you can find an 3.25 Diff for an Mk3 the Turbo A came with an 3.25
I have more pics about the shifter where you have to bang the tunnel etc etc so iff some one need info let me know
Iff you swap the 6 speed you want to go as low as possible (diff)
Mk4 is like 3.2 and Mk3 is 3.73
With te 6 speed and diff 3,73 you have to shift to many times the 1 speed is very short
Butt cool for spinning wheels etc etc :icon_bigg

We (mk3) can go lower then 3.25 :sarcasm:
