Its a rule of thumb for me to not believe anything the dealer says. I was told way earlier on that the USDM STi would be a V6

 

I thought you couldn't use anything bigger than a 2.0? That's why all the other STI's with the exception of the US Spec are 2.0.

The 2.0 restriction is the correct one. They can do whatever they want with the USDM model, i believe the rule to have x amount of cars be in the market for it to be able to be in the WRC was eliminated a season or two ago.

We don't get taxed on huge engines in the US, except the gas guzzler tax and thats based on mpg not displacement, whereas they do get taxed like crazy in japan for anything over 2.0 With that said a 2.5 with twin turbos might not be likely in japan, but they can do it in the US if they wanted to. I doubt they would though, using a 2.5 has already gotten some people rilled up and screaming sacralige.

 

Subaru would probably keep something like this under wraps but I doubt they feel the necessity of going the twin turbo route. With 2.5 liters of displacement and AVCS, it isn't lacking compared with other production turbo engines. And then you have the logistics of routing a turbo on both sides of the flat four. This would require a lot more planning than just increasing displacement.

I hear the next STi is going to be a rotory........

 

what would be nice is a twin scroll setup. but the rumor is that both mitsu and subaru are dropping the twin scroll systems. Why i dunno. But I think an STi that hits full boost by 2700rpm would rock

 

The twinscroll on the JDM STi is too small for the 2.5l

 

I can't see Subaru going TT on an STi... It just doesn't make any sense... That kind of reminds me when a local Acura salesman told me the RSX-S was a 20 liter. I laughed and then offered him $20.
