First, you'll want to get the belt on if you haven't already. THese directions might help you out:

Then, adjust the tension:

Timing is easy. When you put the belt on, make sure the timing marks on the cam gears and flywheel align:

When you've got everything all lined up and put back together, put a jumper wire on the ecu jumper (left side of the engine bar, on the firewall, usually with a yellow dust cover). Put a timing light on the engine, start the engine and shine the timing light through the check hole on the transmission bell housing. You want the timing marks to line up. Directions:

A few other thoughts:
-Make sure you use a torque wrench. The torques listed in the documentation that I sent you are very important and should be followed. The tensioner adjustment bolt is especially important to get the torque right.

-Have you checked to see if there is any engine damage to this motor. 3rd generation prelude engines are interference engines, so when the timing belt breaks there is a possibility that bent valves, ratched cylinder heads, damaged pistons/rods can result.

I really thank you for your reply you dont know how much you have helped me. When I tore down the car both cam marks were up None of the valve springs seem to be hung open and they all seem to open and close fine. I knew about how the cams time the crank gear has a dot on it but nothing to line it up with. Im sure with all the Info you gave me I should have it up and going in no time at all
And Thanks Very Much!!!

Don't you get bent valves when the belt breaks. Run a valve adjustment before you try to start it. If you have some with really loose settings, the valve are most likely bent. Jr NSX
