Are you sure about the EJ204? I looked around on the internet, it seems like it was on the JDM Legacy, which isn't exactly a performance application, and some guy selling it on Alibaba claims 150hp. Seeing how the other EJ20s seem to be around that ballpark I think it's more likely. Only Wikipedia says 190hp, or so I have seen...
And over here I'm still hoping for Valvematic
With the shorter stroke they just might be able to fit in the intermediate rockers, and afterall, the FT is somewhat wide...if they throw it on this car, it would be the first US model Toyota to have it, which would make this car even more special. Due to the huge part load efficiency increase, they could probably give it more aggressive cams for even more power up top without fuel economy penalty. And then adding turbo wouldn't hurt fuel economy much either. It would be perfect
If that doesn't happen, well it'll have to come sooner or later since there's no way car companies can hit CAFE requirements without more advanced valve control tech.
