The IP will not tolerate water. Under high pressure/heat the water will explode violently. These mico bursts are powerful enough to cause pitting in the barrels of the IP. The IP will be ruined in short order.

By "DI" do you mean direct injection ? The glow plugs are in the pre-chamber not the combustion chamber, so, not DI.

The best method of getting water into the cylinder is via the intake manifold after the turbo. You can set up a single injector into the intake manifold or an injector for each cylinder runner.
