porting doenst give you much hp, it just gets your air flow better with less friction. i dont know how much they would cost cause i did it myself with a friend, but it shouldnt be anywhere above $20 for a 20 min job. (if its the same 'porting' im talking about)

Most shops don't want to fool with porting a TB. But if you already know how to port, then you already know to buy a porting kit. Summit racing is a good place to get a nice porting kit for 1/4" shanks. You can use a drill if it's a nice high speed. I used an electric rotary grinder. Air die grinders are very nice too. 1/4" shanks are the ONLY way to go. Don't ask me anything about Dremel tools.

I did port my upper and lower intake manifold myself and IMO, it's a WASTE OF TIME. For the VE that is. But people don't listen. They want to be able to tell their friends that they've done port work to their motor.

Now on the other hand VG30E motors have gotten some nice gains from port work. Be careful when porting your throttle body b/c it has a coolant jacket that you can easily pierce through if you don't know what you are doing. I've personally seen some nice dyno sheet comparison with VG30E motor's with cams and headwork. And the headwork is a very nice thing for the VGs. It's proven. But it's not yet been proven for VEs. In all my inspections, I don't see how it's possible to gain more than 5hp with a nice headwork port job on the VE30DE.

You can check out my porting pics on my webpage.

heh, im always wrong on pricing. this time i was way off, my apologies. porting does help a bit, but only when done right. if not done right, you can ruin your engine by having those tiny bits of aluminum get in it.

LOL! Dude, please don't ever attempt any port work ever. There's more to porting than just keeping metal shavings from going in your motor. Are you telling me that you will port your runners and heads while they are ON the car?

And no, porting isn't as easy as keeping metal from going in your motor.

Haha yeah. Dremel tool won't correctly do the job. And if someway you do find a way to get a dremel tool to do a perfect job, then tell me how many years of labor it took you to finish the job.

dood! if my Dremel is good enough to cut a engine block then its good enough to port a IM

really though, its cheaper to not use a dremel, the bits and crap wear out wayyyyy too quickly. Plus it boggs down too easily

You said yourself that it bogs down too easily and bits break and wear down too fast. Like I said, it will take years to do the SAME exact quality work as if you had a professional porting kit with the right tools.

I'll say it again, a dremel tool won't correctly do the job. Is it possible? Yes. Is surviving after jumping out of an airplane without a parachute possible? Yes, but I wouldn't recommend it.

I did use a Dremel on my TB, and the sandpaper things did wear out fairly quickly. Afterward I smoothed it out by hand.

bah, you need a tungsten carbide swirly bit thing ($8) and some polishing puff ***** ($2 for a pair).
the polishing wheels wear out, i used 4 on my throttle body (p+p front and back). i have 6 for my upper intake and manifold inlet..
also if you're looking to polish stuff just to make it look nice, the carbon steel brush wheel works excellent and doesnt wear out very quickly

polishing puff *****.......

These would have made it alot easier, but i didnt have any polishing compund handy..... I just wet sanded with 2000 grit, it came out pretty good.

Aaron, yours looks a bit thinner. Was the bit you used actual sandpaper, or was it like a grinding stone?

With grinding stones, the aluminum would melt and clog the pores on the stone. So yes, it's a Standard Abrasives porting kit from Summit Racing. It comes with little cone shaped sand paper cartridge rolls. Looks like a cone shaped roll of toilet paper.

Here is a little write up I spent many hours getting together:

Here is the bit I am talking about:

theres no reason to use compound with these things, at leastin my opinion.
