Some people have gotten flywheels machined to have the crank sensor holes. STS Machining does it with the earlier flat flywheels.

I had one on my '89 240. When combined with a better cam that thing rev'd very freely. It was a bit easier to stall though.

Since your car is an '89 I assume it has LH 2.4? In that case you shouldn't have to do anything to the engine block. Just modify the bell housing to have the correct notch for the sensor.
