maxima 88 timing belt replacement

i am reading that the timing belt is really difficult to replace on 88
maximas. But i would like to replace it myself anyway instead of
paying about 300-500 dollars. I have the manuals and know how to
install it for the most part. I just need to be sure on how to tension
the belt correctly when I am done. With this car, can i use the method
of turning the belt about 90 degrees? I do not have anything to
measure the tension with to match up with the book-specified force.
Also, is there anything thing else i should know before attempting
this (besides the obvious risks etc.) ?

I am posting a link to my question to the group. It is for a water
pump on a 96 but I think you will see the similarities. I still
haven't replaced it but I am leaning towards paying the $400 for it
within the next couple of months.
