The engine block is the same in the sti and wrx for the 2.5L varieties.

Engine differences would be manifold, intercooler and turbo mainly. Of which the STi items are the better.

Saying that they are better, does not mean that they are worth it though. Depends on what you use the car for really. I'd probably prefer a new WRX over a 2 year old STi.

What I'm getting at though is most people think an STi is just a big wing and maybe some more boost or something, which is not the case.
