there is only one upper intercooler pipe, there is also a lower intercooler pipe, so maybe thats what you mean by pipeS.
i think hes asking what he needs to have a soild 12 second car.
your going to need a new exhaust, i would look for a supra smic, an evo III 16g with some 650cc injectors and an afcII, a 190lph warblo or a 3000gt vr4 pump or an evo8 pump, some 7's (ngk plugs, one heat range colder, dont know the exact part number),
look here, this might not work for you, but it did for this guy.
