Know-it-alls come! TB mod question..
 

How are you supposed to fill the holes that the throttle plate rod was? It says on the fc3spro site to use an NPT plug to plug the hole and to make the threads with an NPT tap.. 1/8". But 1/8" is way too small..and I went to home depot and nobody knew wtf an NPT plug was, or an NPT tap..
Any help?

just use like jb welb. i remeber someone saying that

Wow, your Home Depot is screwed.

Did you pop out the inner brass bushing?

The NPT fittings are tapered, so not all of them will fit.

JB Weld works fine.

I used a fitting bolt + jb weld

I tapped the bushings ( I dont recall the size right now), And installed 2 bolts with some Loctite Sleeve Lock on the threads and ground the ends of the bolts off

I read a story of someone who took apart a blown engine, to find bits of chewed up JB Weld. So I took mine to a shop and had them weld the holes shut.

If I'm not mistaken, I think NPT is "national plumber trade," or something like that. It's just another set of measurements, like SAE or metric, but for pipe fittings. I think.

i just used jbweld.. kinda worried about it breaking now though..

idea
 

Hm.....How about taking it to a body shop and ask them to weld it shut? They charged me $5 to weld some brackets together...

I used one of those 10mm bolts where the head has its own little flange. It keeps the bolt from going all the way through, and I JB Welded it from the outside only, so nothing will go into the intake.

National Pipe Thread - close :)

Pipe is dimensioned by the inside diameter so a 1/8" NPT plug will fill the bearing hole.

I used some brass 3/8" set screws I had laying around & sealed the thread gaps with RTV.

My rod was rusted in the rear bushing, so I used a 1/8 NPT tap and plug in front and drilled the rusty portion out for a 3/8 NPT tap and plug in the rear. :)

Thanks for the info!

the npt tape is that teflon tape that plumbers use to wrap around like metal pipes to seal them, go back to home depot and ask them for some teflon tape and you will get the right stuff

Are you serious? Tell the people at home depot they're idiots, cuz thats where I got my tap and plugs from!

I personally don't feel comfortable putting JB-Weld (or other epoxy) anywhere it can get sucked into the engine should it come lose. Just take the extra 5 minutes to tap and either install a plug, or just a bolt. It will look worlds better, and there's no chance of it getting sucked into the engine.

what are you suppose to do with the two lines going into here if you're suppose to remove this?

:confused:

bump.. kk thx0r

The simplest way is to connect them together.

Should I use something in particular or can I just be safely creative

I just had to "undo" a JB Weld'd TB by drilling in out.
I don't think it was going to budget.
Unlike NA 6-ports, these are not doused with fuel, and temps are not as high.

This is going to cause people to gasp, but I use plain copper RTV on my TB, and they are still there.  I've boosted up to 18psi, and they are still intact.
