What he said is true. Cams, intake, and exhaust make a stable, powerful NA engine from an FJ20E. And you can always go either two ways... turbocharge it, or carburetors like mine has, and make tons of power.
FJ is epic. CA18ET has potential, but it's no FJ.
BTW, where are you located? FJ20E isn't found everywhere, only certain countries got them.
