I think what Gabkicks means is that no engine is precisely 2000cc even though they are called "2 litre".
From memory the Evo engine capacity is 1997cc (at least in Gp N) and the Subaru is 1994cc.
The later model Gp N cars are generally around the 1350-1400 kg mark in rally trim.
EDIT: Correction: the homologated engine capacity is 1997.4cc
Check out http://www.ralliart.com and go to Group N Information to get the homologation papers for the Evo 7. It's not specific to Galli's car (and it doesn't provide hp or torque) but it's interesting.
i was just wondering because in RBR i'm about 10 seconds faster through a 3 minute japan stage with the wrc car than i am with the gr.n Evo and i was wondering what modifications to the wrc car were making the difference in performance. I hope gt5 has some gr.n cars in if just for the sake of showing how awsome wrc cars are even compared to a really good gr.n car.
Its an awsome feeling getting used to a good car and then jumping into something alot faster.
i know the general specs of group n and wrc but i was looking for specifics for the gr.n evo7 galli drives
