Well Dave as far as I can tell the restrictor is already built into the turbo CHRA, when I get my SD card reader for my new computer I will upload a picture to show you what I mean.
Edit: Right, interesting development. Apparently Pirtek outsource to another company so the Pirtek guy have me their phone number to speak to that other company directly. Said other company is near Silverstone so not exactly local and therefore I can't bring the turbo to them to show them which fitting goes into the end of it. So I will have to guess that part. Why is everything so damn complicated
Edit 3:
I can confirm, that on my GT2052 at least, the oil inlet to the turbo CHRA is the same size as the Lucas pump fuel inlet fitting (the bit that the banjo bolt screws into), which I believe is M14x1.5 but can anybody confirm that? Thanks.
