Good that you have it working. 

The only timing I do on these engines is the IP timing.  I have heard you can advance the crank and increase the IP timing but I don't know it that works or not on the 1.6. 

Maybe some of these folks that build their engines for insane boost and HP can tell you.

 I had the timing set with the flywheel mark off by about 1/4".
 Lost power in the midrange.
Not sure which way it was off.

My mark went about the same but to the front of the car. I will try the opposite side a bit and do some tests.

I overtightened the cam sprocket and now it won't come off, any advice?

To remove the nut on the cam you can hold the cam itself with a wrench on the lobe and apply pressure to another wrench on the cam nut.

Are you pinning the IP with some kind of socket or bolt or the actual pin needed to keep it from rotating while you put the belt on from the bottom up?

The Crank should be set on TDC first then bring the belt up to the IP, then between the tensioner and the cam.  I put the belt on the cam last as a loose pulley can turn a bit to get it to find a proper spot between the grooves on the belt and pulley. 

Once I have the belt on I bring the tensioner up tight and check to be sure I have not moved the crank position in doing so. 

It is an art more than a science as there are a few moving parts that can all move at the same time making it difficult to keep it all in line. 

Maybe you can have someone hold a wrench on the crank nut to keep it from moving as you do the tensioner?

No no i remove the bolt but the sprocket wont come off the camshaft, hitting it with hammer from the little hole but no luck.

Soak it down with penetrating oil.  If you had it able to move before it can't be on there that tight.  Try you punch on both sides of the shaft to get it to come free.  Wiggle it a bit by tapping lightly, very lightly on the edges of the pulley itself.

Or use a gear puller.
They make special pullers for that sprocket.
