i have my intake off my car, and i'd like to port the whole behind the throttle body to match up to a 58mm throttle body while i have it off the car, but i won't be getting a 58mm throttle body for another few weeks, will it hurt my car to port those holes larger until i actually get a 58mm on there?
also, what should i use to port it, just like a dremel?
and what exact size do i need to make them,
thanks in advance

Won't hurt. Usually use the TB gasket for the template.

Dremel would work. JMHO.

If you beleive it is important, have them make a print of the gasket and have them fax it.

Maybe if you sweet talk them they will do it.

 

nobody wanted to do that for me, jackasses, i would have done it for anyone. Even then, i dont know how good that would have been compared to using the actual gasket.

When i got the gasket on there, i realized it doesnt line up with the stock holes. You can port them now, but you will have to report them again anyway.

so there's no getting around the gasket.

I used a drill with a grinding bit. I would not do it that way again.
