Today I was trying to drill a hole in my engine firewall to run some wiring, and I broke two drill bits!!! Let me just add the the result was just a bunch of scratched paint. The best place I can find to drill is at an angle, and the drill bit will not bite into the metal, it just breaks. Where has everyone else drilled there's? Looking for any comments or opinions, it was a BIG setback today. Thanks in advance.

Just in case you didn't know, there's already a hole in the firewall you can use... it's near the middle top... look for a rubber grommet and take it out. Then you can drill a small hole in the grommet and run the wire through it making it waterproof. Saves you from cutting up your car.

I drilled a hole in my firewall to run
1/0 gauge cable. I learned.... first make a good
dent in it with a punch tool. Then use a smaller sized
bit and run it at high speeds. Make sure you're drilling
straight, and not at an angle. After you have the
hole, use a dremel tool or something similar to make it
bigger until it works. That's how I did it.

the NOS electrical wires.. yes i will run those through that same hole to the ECU..
the NOS stainless steel line is run under the car.. next to the fuel rail..
The hole is right above the fuel filter.. as shown in that pick.. on the driver side right behind the intake

Thanks for the input everyone. Sprintmax, did you run your amp cable through the same hole Ants is talking about? Where are you running your NOS wires? Thanks in advance.

Which side did you mount your bottle on? Did you have to drill a hole for the NOS line, or is there one I haven't found yet in the trunk? Thanks

Which one Sprint? I have a couple rubber grommets, does it matter which one? I don't see anything I can damage, but you never know... Thanks.

Use a unibit -->
It's best drill bit for large hole through sheet metal. The bit doesn't jump around. It sort of grinds as it drills to give you a smooth round circle.
Here are some pictures of the large holes I drilled.

I drilled through on my third gen by using a small drill bit to make a small indentation in the metal, then switched to a full size and just pushed really hard. It eventually broke through. The indentation made with the small bit helped keep it from sliding since it was at an angle.
Had to shape it a bit, but once I got that done and popped a grommet in, it's real clean and snug.
Used it for my amp power cables.
