The new Mechanical LSD Differentials page is now up. I hope it is as informative and educational as the pages I produced ten years ago.
Most of the new brake parts have arrived. Just waiting on the 2nd hand R33 Gtst calipers and new pads all round.
I have a license for the Nistune software and a consult to USB cable on the way. Soon I can plug in my laptop and see what the ECU is doing in real time. Hopefully then the non working VTC can be diagnosed and rectified, giving the car some much needed low/mid range torque. Connecting the electronic boost controller after this will then add even more.
