Would have been so much better if you'd said all that in the first place.
So. Now once again I suggest you go to find the rules and look at limitations and limits...
Everybody will be at the limits..
Thing is though in the end, it is not the motor which is decisive...The whole package of the team the designers , the mechanics, co-driver,,,EVERYTHING..John Vanlandingham

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)

Well have you searched and found anything?
Aside from bore and stroke on VW, and Ford being all more or less the same 83 x 73.9 and and Citroen 82 x 75.5 which took 0,2 sek to find..
You don't seem very interested in discussion of this subject...which is odd cause you started the thread.. and it is usually hard to have discussion with one person only...John Vanlandingham

Yes I have found that information from the teams/WRC site, but I've just been really busy with some school things. Also I have found a site with pretty much all specs of the cars from -2010.

Why do you think Citroen have gone with a different bore/stroke configuration? Their torque specs seem different from the other cars as they top out at 350Nm but at a lower rpm (3250rpm), where as the other cars are in the range of 400-450Nm @ 4000-5000rpm.

A pdf from the Race Engine Technology magazine (Jan 2012) which has a 10 page article on the Fiesta WRC engine. I remember when I read it back then, it is quite technical

One thing for start. Never ever trust in official numbers in motorsport. Especially in rallying there is a long history of showing bullshit in PR materials.
350 Nm @ 3000 rpm is realistic for DS3 R3T which uses different engine than WRC and also smaller size of restrictor. R3T uses modified stock EP6CDT engine with long stroke configuration 77 x 85,8 mm.Stupid is as stupid does. Forrest Gump
