On the MY99/00 the standard restrictor was 1.2mm if IIRC....

Did the PPP for those model years change the size of the restrictors - or did many PPP cars require it changing?

 

No, it's the same exactly size but from what I know some cars need new restrictors (>1,2) due to overboosting problem even if they aren't further modified. I haven't yet problem with mine (MY00-PPP) but Mr Banks could help you as he had this problem with his car. On the other side our climate conditions are so differents!
Hope this helps you mate.

I had 1.3mm without the downpipe and 1.35mm with.

 

Cheers guys

 

Forgot to mention I haven't had overboost problem so far and except the PPP I added recently an PE exhaust manifold and Magnex downpipe.
As you can see from my Delta Dash log files I have 15,5-16psi (depends on ambient temp) steady boost pressure on 4th 5th gear and car is very smooth. Our temp this season is 30-40 Celsius degrees, will see the difference on winter temp.
