Rebuilding a NT throttle body
 

Can anyone point me in a good direction?

Right now I have bad leaks around the shaft seals, but I'm finding any replacement seals, I think that I can use turbo ones but I have to have this TB shaft bored out or something.

I could of swore I did this a few years ago. :flamethrower:

Put in DSM turbo shaft seals backwards. They won't go in all the way, but I don't know of anyone who has the correct ones.

Ok, I think I had someone who used to be a member on here enlarge the bore where the TB shaft is last time so that they would seat better.

I'll try that though, they leak terribly bad on my car.

I found this post on tuners:

Tsunari:
"For future reference, you can have the body of the NT TB where the seal goes bored .040" deeper and the turbo TB shaft seals should fit. For some reason, that recess on the NT TB is only .100" deep as compared to .140" deep on the turbo TB.

Or perhaps dig around for a seal similar to the turbo shaft seal but something not as tall

****EDIT****
1G Turbo 10mm x 14mm x 3mm

1G NT 10mm x 14mm x 2mm --- If you can't find a seal like this, bore the recess 1mm deeper (a total of 3.5 - 3.6mm) and use the Turbo seals

So i guess next step is too find someone who can bore out the part where the seals sit for me, and I'm picking up some mil.spec turbo TB seals.

Just bore them out and use the seals, I did that on a 75mm Ford style TB a few years ago, worked great. It takes a goofy size drill bit, I have it laying around somewhere.

^any chance you can find that drill bit?

Re: Rebuilding a NT throttle body
 

Yep, I have it on my workbench, or just bring your TB over and we'll throw it on my drill press.
