Its a moderate job... Depends on your abilities... But usually, no matter how good u are machanically, its gonna take some time if this is your first time doing it, so allot atleast 4-5hrs for the whole job... You dont have to pull the whole motor, only the driver's side mount (while placing a jack with a peice of wood to support the engine, under the oil pan)... Heres a how-to on a Del Sol, but since ur car is SOHC, its essentially the same... U might want to pick up a Helms manual, or atleast a Haynes from Autozone or Advance, if u dont have one of those handy, it will explain the specifics for your car... Like the torque specs and all that...

Dont forget to check, and recheck the timing marks before starting the car!
