Well, the EVO x you get about 499 bhp in, an a bit over 1200kg. It is very good to drive. But I have not tested it enough. The Evo IX you can put a race mod on and get about 515 bhp, with racing soft I got laptimes of 6.40 on the Nurburgring.
The R32 gets about 666bhp and weighs about 1250kg. Best laptop on the ring for me is 6.50.
I know you can get over 700 bhp in the R34, but I have not tried it yet.
