how hard is it to change injectors?

[Hatzenbach]

So I am toying with the idea to install a Turbo kit in my car
It seems that by far the hardest part of the whole job is to replace the injectors
I looked into "101 projects" and it doesn't look so bad in the book, but then again this was for an engine which is not in the car.
Can someone tell me how much of a pain in the neck it is to do this job with the engine IN the car?

Access is pretty easy, although I believe you need to remove the air cleaner or at least loosen it up on the left side of the car. It's not too difficult at all...
