I think your wrong there. They do run 2.0L engines so they can race.
He's not wrong.
The USDM STi, just as he pointed out, is not WRC eligible in the same class as the 2.0L JDM STi.
With that said, the 2.0L JDM STi with the closed deck setup, forged internals, and a 1-2k higher rev limitation, version 8 block is used. It produces about the same power, but through higher revs.
...and I'm saying that they're going to *NEED* a h6 to compete in the near future. The 2.5L WRX is brembos, 6spd tranny, turbo, injectors, intercooler, and a cheap suspension away from the STi.
Eliminate the 6speed tranny, if you don't care about the 6th gear. Write an Evo 16g turbo off as $800, injectors $500, intercooler $600 depending on what name brand, ebay is much cheaper and works as well since its huge, and suspension $1000. Basically you can buy a new WRX, and outperform the STi for ~$3000 in virtually all aspects.
There's really not that huge of gap anymore, and thats seen by the new Stage 2 WRX's destroying stock STi's. The cars are practically identical with the really expensive differences being the 6speed and brembos. (4pots/2pots work nearly as good for a street car though - upgraded pads, fluid, and lines and you're virtually the same).
This is why the S203 limited is coming out to America in 2007. Its a toned down version of the STi in terms of looks. A nice front lip, no huge shopping cart wing, and it has luxuries like leather and big ass rims. They're trying to differentiate the STi from the WRX some more.
Mark my words, eventually the difference will be a H4 in the WRX vs a H6 in the STi.
...oh and the next redesign was rumored to be as a hatchback.
