Well, that depends on how much your time is worth, and how many seized rusted bolts you'll encounter that need drilling out
I started mine about 2 weeks ago, made good progress for a couple of days, and then things started getting real slow on account of the fan not wanting to come off, nor the crankshaft pulley. Then again, if you've already excavated down to the timing belt idler pulley, that's most of the way there, and none of those bolts should be seized since you've recently had them off. In which case an inspired weekend or two should do 'er.
