Rb25 oil gallery restrictor

[MartinS]

After several hours spent on the internet I found two topics about oil restrictors for the Rb25 head.:

The problem is, that I measured the galleries in an 33-RB25 94', and my results are completly off. According to the paper and the tomei website, it should be arround 2.0mm. My meassurements should something like 2mm for the VTT unit, and 1.2 for each of the other two oil feeds.

Can anyone elaborate on that topic? Did Nissan learn from the early mistakes and improved the oil feed?

Thanks!Martin
