Hey guys!

Want to port my throttlebody, what has folks here done, did you dismantle the motor, tps and blade for this action and is it possible, see some special torx heads on the screws?!

Ok, i choosed the way to let everything on the tb while porting, scared a little bit, something can damaged while its turning on my lathe?!

Next step i did, close this ugly oil steam inlet in the front of the tb with liquid metal:

I don't know of anyone using a lathe to port a throttle body. I used my Dremel and some carbide bits to take the meat off, then a bunch of varying sand paper drums to smooth and clean it up. I kept a junk throttle body plate installed at all times so I didn't screw up the diameter and go to big or wonky.

The main objective in my eyes was to get rid of the hump in the airflow path and smooth the transition to the blade. Some people knife edge the blade.. I didn't really see how that would make flow any better and may actually hurt flow.

Edit: Some parts of my response have been deleted, I'm an idiot.. didn't realize it was an electronic throttle body.

Yes, you are right, i will also use a grinder, bec i´m scared about high rpm on lathe with Motor installed on my tb...

You have pics of your tb?

I'll have to dig around my files when I get home from work and find some. If I can't find any I'll go take some quick. It's pretty stuff, I did my 5.3 truck as well.

If you take the blade out make sure you get it in the right position when you reinstall it. The one in my truck needs adjusted, it gets hung up some times, it's annoying.

I tried porting mine with a Rotozip and bit. Seemed to work, no codes and pulled hard. I later upgraded to a 85mm TB.

What's the correct definition for the torx bit to get the blade out, tried mine, have all numbers, but there was no really matching, is it inch maybe or something special?

And did you all shortened the screws backside, there is a thin pin on it?!

Sent mine off to New Era.

I chopped the screws down to the size of the shaft on mine. Not sure how much it really helped, but I did it no less.

Now here is the result, not the perfect surface on every side, but still better then oem i believe:

Save yourself the time/hassle and send it out to get ported for $75

Choppy_Idle

$75 with filling the hole, shipping 2x from/to Germany and tax???

And where is the fun, giving all my parts to a shop, let them do the work which I can do also, sorry I'm not that type of guy, will build the parts by my own, if possible...

Sorry didn't notice your location. Porting/polishing isn't just going to Walmart/Loews and buying a Dremel or " lathe" and some sand paper and have at it. You can mess things up quick if your not careful and don't know what your doing. Plus the right bits can get costly. It just sounded like you didn't know what your doing so I suggested sending it out. $75( didn't know location) is cheaper them buying a new t.b. when your "lathe" burns a hole through it! I also sent mine to new era and it came back perfectly smooth! They also ground down the throttle stop!!
