I just wondered,other than the colour,what the differences are between a WR1 and a normal STI with the PPP.

The main difference i am interested in is how the WR1 is supposedly 320bhp (if i am right),and yet the STI PPP is 305bhp,and would it be cheap and easy to upgrade the STI PPP to the same engine spec??

Cheers guys .

 

Main differences would be as you said, the power increase (which I'm not sure whether it is achieved through a different up/down pipe or maybe just different mapping), DCCD (when compared to an STI of the same year), the 18" alloys, the WR1 had Prodrive springs as standard, not sure if it had different shocks though.
