To get a reliable 230-260 you would have to go full out swap.
Maybe Ej22e(ej22t) from a first gen leggy or something more serious. You would still have to go full standalone, full exhaust, turbo, injectors and supporting mods on that motor....
i kinda like the 2.5 plus i dont realy wana do major swap. i mean we rebuilt the motor its almost got all the bugs out of it last one is bad injectors which is slowley getting worse but how much do u think it would be for a like a wrx/sti motor im gonna say not new
