I agree with just_ace's post on parts cost, depending on where you get them.
But if scourcing parts yourself, be aware there are some diferences depending on the model.
 
I got my timing belt stuff  from Road and Track.
Much better prices than the local Toyota dealer, and they helped me get the right parts for my motor. (There are different types of rollers, tensioners, belts etc.)

^wow that sounds really cheap!
NA or turbo? 

MRTurbo is was for a '89 turbo. Drew like i said I had to wait for the parts to arrive and had it done in a week and a half. If you could find all those parts yourself you may be able to save alot of time.

Yeah mine was done without removing the engine. I think the higher quotes are for removing the engine maybe?. At the time i thought if it was gonna cost more than 1.5k and they were gonna remove the engine, i may as well buy all the upgrades i wanted intercooler turbo and may as well rebuild and strengthen the engine.
