Okay I think I see what happened, a bit of an understanding error on my part. The VW EA113 HPFP internals being mentioned are the APR internals that are available for the MazdaSpeed because they were produced by Hitachi for both our platforms with minor exterior differences but the same internal specs. There is not a retrofit of an actual HPFP from a different vehicle (also this VW one was more expensive than a new one from Mazda, so not even worth it to save some $$$).
As for the roller bearing tappets that’s interesting to know that it can be retrofit, but I don’t know if there is anything to gain from that other than maybe some reliability and less wear and noise.
If I’m still mistaken let me know, but that’s what I gathered from some research based on the link provided.
