May be this a bit late reply, but do a compression test to see if you have a blown gasket ( check harborfreight), second it happened to me, the radiator was leaking around the corner on top of the tank, of course it was steam coming out when the engine was at the operating temp, and you could not see any leak when the engine had cooled down. you also can get radiator pressure tested. check the hoses and flush the radiator and flush by garden hose from the bottom., then add new fresh coolant, notice most leaks occur when the pressure built up inside the cooling system, look for steam from pin holes, you should remove the belt to prevent the fan from turn, of course for a short while to see where the leak is. Mine has 157K on it still going strong, don't give up on the engine yet, at 90K it has not even broken in. If you decide to go with JZ engine get 2JZ, made for US not JDMs . supraforums,com is where the guys with turbo and engine swapping are, get advice there is alot to it then engine swap. good luck
