I'm replacing my 2G Throttle Body with a 1G one and I need to port-match my stock intake manifold to the new throttle body.

Can someone link me to the head attachment for my dremel that I will be using? I'd prefer to be able to go to a store to buy the head rather than order it online... I'm kind of in a rush. Pictures would be great too. I have the dremel arleady.

Thanks

Even though its not that much material and aluminum, you may want to invest in a air die grinder. It saves time, works better, and is cheap. Harbor Freight sells them for about $5-10.
And they usually come with a bunch of bits, etc. Look into it.

With a dremel, you would really only be using stone grinding bits, which are crap.
Or something like this:

And the above bit is the price of that kit from HF.

More serious porting without a large air compressor would be best done with something like this:

But for this little bit of porting a little wait with the dremel should be fine. Any of their harder grinding stones should do.
Aluminum oxide grinding stone:A high-quality industrial abrasive made for extended general-purpose grinding on metals, castings, welded joints, rivets and rust.

It's the only self-port job I'll ever have to do. I'm okay with the $8 tool but if its up in the 30's 40's I don't think its worth it. Anyone know of a STORE where I can pick up the grinder tool? Again, around the same price range. Thanks!

Sears, Homedepot, Lowes, Walmart, sometimes places like Pep Boys. That should give you enough places to find them.

Go to Home Depot and ask for the carbide bit made specifically for the Dremel. It looks like a small drill attachment and it's made for the Dremel and Dremel XPR. I just did this a month ago and it worked out very well. I recommend some shaping stones to smooth everything out when you're done or some drum sander attachments with 120 grit.

I used a dremel-type tool and the high speed cutter (I think that's the name of the bit). Worked fine and cut through the aluminum rather quickly.

I used a Dremel and carbide bit and sanding drum to open up my intake mani too. It was fairly effortless....minus cleaning up the mess.
30k rpm Dremel's are kickass

Hmmmm... on that note my crafstman goes up to 35k. Maybe I can use that then.

just wear saftey glasses , and an idea is to put a shop vacuum on the other end of the mani to suck ebverything up,or if the vacs not strong,tape its nozzle to the side of you dremel and itll suck up the shavings while you work.

To add on to that, I would wear one of those cheap masks from walmart or something because of the aluminum dust. I would also suggest shoving rags down the mani to stop any shavings from falling or being thrown down the runners. I did that and the tape trick...that's where you covered the opening with rags and put tape, rolled onto itself, so that one side sticks to the rags and the other catches a good portion of the shavings/dust.
That trick caught a good portion of it alright, but the rest dropped in front of it due to being covered with shavings and dust. That wasn't bad either because my shop vac took care of them

Note on the carbide bit, it will "bite" into the aluminum so don't hold it lightly or it will dig into mani and be prepared to get cramps on your hand(s) because of clamping down on the rotary tool of your choice (again, noted for carbide bits).
