View Full Version : Ported a little too much of my throttlebody!

11-16-2006, 06:14 PM
So I thought I'd give porting a shot and apparently I took off too much material :bang: I now have a very small hole in the TB as shown in the pics. I had to shine a light on the other side of it to get it to show up in the pics. I'm done porting it (no need to sand it smooth and polish the inside as it's only going to marginally help air flow) but can I still use this thing? I was thinking maybe a little glob of JBWeld in the hole on the outside of the TB and then sanding it smooth. Do you guys think that would be ok? I really don't want to buy another one on ebay. Oh and it looks like there's still a ridge where the metal goes from smooth to rough (where the TB blade usually sits) but that's not's actually a smooth transition with no obstructions :)

I have one that is almost done if you need it. It has shaft cut, the bump stop mod, the throttle blade knife edged, its ported and polished very nicely, and has the throttle blade drilled out. I am just waiting/deciding whether to fill the idle bypass or not.

thanks for the offer but I already cut the shaft now I just need to grind it down for the bump stop. I want to salvage this one if at all possible.

jb-weld it?

11-16-2006, 07:14 PM
IT IS GARBAGE.. so you might as well send it to me.. :)

i think JBWELD should work just fine.. i would apply it from the outside of the TB and then sand it smooth on the inside (very carefully).. make sure the outside of the TB is really clean befor u put the JBWELD on

I dont see why some jb weld wont take care of that. Give it a shot, what have you got to lose....

11-16-2006, 07:29 PM
I will send you some 2 part epoxy. PM me. I've done it before. It will be fine.

11-16-2006, 07:40 PM
That happened on my throttle body. You can just use some epoxy to cover the hole. No reason to get rid of the throttle body.

11-16-2006, 09:05 PM
epoxy it on both sides and then sand it smooth. that's what i did when i got to crazy with the grinder

11-16-2006, 10:21 PM
Jbweld is your best friend, apparently you missed the go easy cause some parts of the throttle body are thin warning, lol

jb-weld it?

+1. Another vote for JB Weld... GREAT stuff.. ROCK hard and bonds to almost ANYTHING!

JB weld will work just fine.

I did that to one of the TB's I ported. I used JB Weld or metal filler and it worked great. Nice thing about the TB is that it doesn't get super hot and there is not a lot of stress put on it.

i did the same thing on mine, my dad had some high strength metal adhesive (similar to JB Weld) that he uses on some of his models, it worked great. i've driven the car alot and checked it several time, and shows no signs of letting up.

11-17-2006, 12:53 PM
Put some gum.LOL, JB weld will do the Job. Good Luck!

man i love jb weld my car would not be running if it werent for ol' jb

11-17-2006, 06:03 PM
JB weld time :) Just make sure the surface is clean (perhaps use brake cleaner on it first).

11-17-2006, 06:07 PM
i did this also and used epoxy to fill it....

I work with epoxies. We fix concrete with the 2 part mixes it would be great for a throttle body. My uncle uses epoxies when he makes golf clubs.. soooo many wonderful uses for this new "super glue". Check with Home Depot, Menards, etc, they should carry something similar. JB should be ok too if they don't and most people have some of that just lying around.
