It is look like ruler with 0, 10, 20 number XXXXXXXXXXXXXXXXXXXXXXXXXXXXX The timing scale will have an "A" at the top and a "B" on the bottom. In the center is a "0". The "A" is for after top dead center. The "B" is for before top dead center. Each mark on the scale is 2 degrees. Timing is always set on before top dead center.

I have a 1999 Oldsmobile Intrigue 3.5 liter, I will like to know were the Timing chain marks.

on the harmonic balancer the big pully in front of the motor it will be a line the timing marks are visible from the front of the engine looks like a saw
That is the round thing on the top rear of the TBI. The thing that looks like a carburetor.
I could be wrong, but I have a Vortec 350 in a GMC truck and I think the computer handles the ignition timing. If your talking about valve timing I would assume there are marks on the timing gears like the days of old, but I haven't torn the timing cover off of mine yet.
There are 3 timing marks to consider on timing the Mazda r2 just like any engine. crank timing, fuel injection timing and the valve timing. these 3 have markers to align. The crankshaft have timing marks on the pulley pointed by a pointing rod. 4 lines marks the timing. the crankshaft is dead center on the first cylinder whene the pointer is pointed on the center of the foul lines. The injection pump is marked by a line on the pulley and the notch on the plate of the front cover. The camshaft is marked the same way. Be sure that you rotate the pulley clockwise to align these marks to ensure tightness of the timing belt.
make sure the camshaft sprocket timing mark is aligned with the upper back cover and cranksaft sprocket timing marks align the crank mark with the cast-in mark on the front seal retainer.
air intake system like k/n better exhaust , muffler like flowmaster would be a great starting point
