Im looking 4 sugggestions on a new Cams

I have a 2000 celica vin#jtddr32txy0063151 and am wanting to upgade my cams but having issues finding any?? I am looking for something to bring it up as much as I can without other upgrades, As this is my sons car and must keep it real due to lack of loads of $$$. Also need exuast timing gear & new actuator gear for Intake side. 1 other question as stupid as it may sound is this a 1zz or 2zz model. And maybe any other affordable suggestions. Thanks for the help
