EVO IX would be my pick...
can get ~260rwkw with basically e85, an exhaust, boost controller + tune which in an AWD car that weighs only 1400kg is pretty damn fast
beyond this the car loses response and starts to suck up dollars so they are easier not to mod than a GTR
a 34R will just end up being a 350+ rwkw moneypit if anyone in vic WL buys one. I know mine would
