Rebuild is about 2600.00 locally here to bring it back to new factory spec conditions. Performance, sky is the limit really. You can also get a JDM motor for around 800.00 or so. But I still suggest, as do the people who sell them to you usually, redoing the headgasket, and while you got that off, resurface the head and reseat the valves. Not sure on the cost of resurfacing and reseating tho.

As for which you do, I can't really tell you which, but at least you have some info on it now.

If you do it yourself, You can rebuild it with arp bolts, a whole rebuild kit, and a new toyota headgasket for under 1000. That includes new timing belt, oil pump, bearings, and all gaskets, head and bottom end bolts. The the only parts I would say replace after that are plugs and wires, cap and rotor, check all your connectors and sensors via the tsrm with a voltmeter and replace if neccesary, And make sure your TPS is reading the correct throttle and your base timing is set, And you have a motor that will run beautiful. If you want ot go a step further, get the head rebuilt too. You can just test it by laying it upside down and filling each combustion chamber with rubbing alcohol or diesel fuel. If any is gone after a few days, Get the head rebuilt. But otherwise it should be OK, just not perfect. And then after you get it backtogether get new hoses and belts and a new water pump, and do an oil change immediatley after the rebuild. Its also a good idea to get an oil pump primer and run it after the engine is assembled to get oil on everything before startup. Or you can use assembly lube, But then you have to flush your oil (or change it 3 or 4 times).

thanks 4 the input

I forgot to mention with the head test....If you feel any moisture in the runners rebuild the head....of course some is going to evaporate after a few days, dumb self! And of course if you notice it going down right away thats not too good...
