so 2.0 L 320 hp vs 2.5 L 300 hp.. we got shafted
Where did you get the exact evidence that the 2.0l outputs 320hp? I have read magazine articles about the R34 Skyline where they were saying that the 280hp is not the true output of the engine. I have heard quotes of 300hp, 320hp, 295hp, 290hp, etc. So in other words, unless I see a dyno test with the hp and torque curves, I'm not gonna believe anything. But, you are correct about that part of Japanese automotive law.

Next, do you really think we got shafted? Think about this. We have more grunt in the low end because of the higher displacement. The 2.0 has less power than the 2.5 at lower RPMs until the turbo kicks in. The turbo lag is lower than the WRX obviously, but before it kicks in, it still has less power than the 2.5l. The motor also might have a the capability of handling higher chamber pressures. (ie it could handle bigger better, badder turbos) We also get past the emmissions regulations that the US and especially the CA govt requires with the 2.5l. If we get the 2.0l we also might have run into the hp situation of the EVO VIII with the lower octane fuel offered here. Would you like to have a 260hp Sti instead of a 300hp Sti? Note also that a 2.0l engine that has 280hp sqeezed out of it is much less efficient than a higher disp engine that outputs 280hp. It burns fuel more efficiently and this translates into improved fuel economy with literally no reduction in performance. You can't try to squeeze 300hp out of a 2.0l engine and have it efficiently burn fuel. Why do you think the twin-scroll turbo system was introduced in the 2.0l in Japan? To make the 2.0l engine as efficient as it can be without increasing the disp.. We don't need the twin scroll system with a higher disp engine. I don't know too much about twin scroll turbos, but on the Garett site, they have a pic of the twin scroll system and it looks more complicated than a regular turbo. This might mean that it is heavier and more expensive. Point is that there is much more to the debate over the engine types than the comparison of power output.

P.S. - I hope my college education came in handy .

Rich, I got this from your post. This is proof of what the 2.5l can do. Those who aren't sure of the 2.5l, take a look at this site. This car is running on 23psi of boost!!!!!!!! The output is 600PS and 494 lb-ft of torque.
