is there any way that i could drill out the stock injectors to get more horseys in my 93 w250? and if i did what size bit should i do it with or how should i go about this? i remember hearing someone saying that you can do this, but it's expensive to play around with, so some opinions would be good. thanks, Gregg

sounds like a bad idea to me if i were you i'd send them out to get EDM'd or honed but dont do it with your drill and a bit

Sure, it can be done. But you run the risk of ruining the spray pattern, and the injector. N fer the price companies r charging for cores it really isnt worth it honestly.

Theres a ton of companies and options for injectors. U just need to figure out your ultimate goal.

The drill bit would be a little bigger than a human hair. Those holes are tiny.

Stock IC trucks have .009" holes.... that's a small bit. I don't think drilling them out is a good idea.

I'm sure there are smaller bits available but I don't know where. A number 80 drill is .0135 inch. That is the smallest that I have ever used and it took a milling machine with a special minature chuck with a finger feed and 4300 rpm too prevent breakage. I have read here that POD's are .0140 inch at the tip holes. At only $440 plus s&h I would go that route instead of risking tips that cost $85.00 each. Now if your tips were as bad as mine they probably need replacing anyway. The choice is yours. By the way, I thought of doing the same thing but I let the stock injectors get away from me in another deal. Oh, be ready to have them edm'd. To my limited knowledge, that is the only way that a drill of that size can be removed without further damage if it gets chip bound and breaks in the hole.
