I strongly disagree with putting grease on the bit. The idea of that is to get the shavings to stick to the bit which to me is flawed. Drill bits are designed to draw chips up and out. If you use grease theres a good chance a grease laden chip will end up inside and make it difficult to vacuum out. Start with a smal drill and work your way up one size at a time. That will produce very small sized chips making problems much less likely.

Besides, it size bit you have to use has wide channels and you're not going to draw everything out.

I drill and tap all of my own and cust installs with the engine running, gets a little warm but have never had a comeback, IMO, If you want true safe reaings you need to put the probe pre turbo.

I did mine by drilling a very small hole, then increasing a few thousandths of an inch at a time until I got to the right size, then sucked around real good with a shop vac, then tapped the hole and sucked'er out again...worked fine for me.
