WRC Engines

[Zeakiwi]

I would like to compare all the spec/dimension of the engine and its components but I was having trouble finding the information so I thought their would be some experts on here or some people who could put me in the right direction.

I am merely trying to gain some knowledge on these specific engines to help with my thesis that I might write on a aspect of World Rally Cars.

Going on past experience most people usually learn more about things they can get their own hands on or at least work with or be associated with people who are working on a particular item, they can put questions to.
Do you have local shops working on Subaru or Mitsubishi engines or Nissan engines? A Subaru ej20 can run 600hp in quite long distance events (more stage mileage than a wrc event) https://youtu.be/FubiykFyW3w (the competitors are supposed to keep below 220km/h, acceleration is ok too)
