Does anybody have pics on where to Port and Polish the throttle body at. I tore it all down and cleaned it now I want to P&P it. Any pics or how to will help greatly. I searched and did not really find anything on the subject, so if I missed it then my bad.
Well if you look closely at the TB you will notice butterfly's are the smallest passage in the throttle body and you cant port them out, the rest is all larger then the butterfly's so there is no point porting it.
um thanks. ok im going to just polish it. I figured I could at least knife edge the butterflys and cut the center shaft in half that holds them and shorten screws that hold them. Any and all small mods add up. LOL. I really like your blue and orange mx6 that you had built that I see on here.

The butterfly's edge (lip) is cut to sit flush against the TB, knife edging the flaps would crate sealing and idle problems.
You can take down the center shafts some, just mark the parts of the shafts that face the front (mouth) of the TB when the flaps are opened and shape them like the edge of an airplane wing, just make sure not to take any of the rod down passed the outside edge of the flaps or air will get passed the flaps when shut and mess the idle up.
Page 1 on the cardomain link below has pics of intake and throttle body port work (also page 5 or 6).
Honestly the time required for the process and the mere 1-3 hp increase is hardly worth the effort. If you want more performance try making an adapter place for the tb and incorporate some larger tb. Of course you need to figure some way to keep the pwm and idol valves operational. Just my two cents. Look at a single 65-75 mm mustang tb.
Nitrous is like a hot chick with a STD..... you know you wanna hit it, but you are afraid of the consequences.....

Bullshlt. You're talking out of your ass. There is plenty of room. You can knife edge it just fine without gettign anywhere near the edge where the butterflies meet the housing.

WOW. You go from one extreme to the next. You tell a n00b not to do something that can be done, to telling him something that you did, that he can do, that could easily ruin his throttle body in the process.
I have done both - porting and polishing the throttle body along with grinding the rods. I would never suggest that someone grind the rods over a simple porting and polishing. Thats so backwards man.
If I could post pics then I would point out areas where I believe i could see small improvements with a little porting and polishing on the throttle body. ANy and all mods add up eventually. Hmmm sixsick6 you got me thinking now. I checked out the web where people have done mustang and other cars TB and did the knife edging. One must just be very careful and not get to close to where the edges are and where they seal the TB shut when its closed,yet when open like an airplane wing I blew smoke through it and could see the flow and after knifing it there would be less resistance I believe by grinding top bar off, knifing plates and removing rough edges in the entrance and a lil around the edges on backside. The 2 area where the sensors are could be ground back some too.

I know what my newest video will be about now.
Alright another insightful, informative and well phrased youtube video, will it be about how you cant read?
Berserker "I figured I could at least knife edge the butterflys and cut the center shaft in half that holds them..."
"Knife edge the butterfly's"
Please Six explain how you can knife edge the edge of the brass (or copper) butterfly's (flaps) without getting close to the seating area when the edge is the seating area?
I have never ground down the shafts on any TB in my life, my first advice is that it's not worth it and when he suggested cutting off the shaft on one side I suggested transitioning it's shape to be more aerodynamic.
What I did was port the TB's and install the large flaps from auto TB's in 5speed TB's giving them two large flaps, I never suggested that Beserker do that.
Glad to see you jumped in the thread with valuable advice and constructive criticism.
Berserker maybe you meant knife edging the throttle body between the butterfly's but if you didn't you can take my word for it or Six's, he has lots of posts.
you guy need to stop, its irrellivant, too much effort to no gain. invest those time in something that will make a different like porting the exhaust side of your stock turbo, now this will make it flow better and give you up to 20hp

Quit adding irrelevant shlt like they're my thoughts, they aren't. I never said anything about "knife edging butterflies" he did, and you suggested that he "take the shafts down" which is a horrible suggestion compared to porting and polishing the throttle body - which you said can't be done - or shouldn't be done/meaning it's pointless - you're completely wrong and I invite you to take another look at a throttle body and see just how much can be removed safely - if you do it right.

It's pretty obvious what he meant - not to you though. I know exactly where he's talking about. Maybe if you didnt spend so much time hollowing out cats and huffing the spray paint in your engine bay.....just sayin.
Carnage - take a look at your throttle body again. If all you did is install another larger throttle plate, you missed a lot of porting and polishing that can safely be done.
ppl on here have went and got a auto throttle body. the top port on the auto is bigger and the stanard one had the bigger hole on the bottom.
I was wondering about that.... anyone have input or experience as to gains from this?

Well sure, I can give my own observations since my current car was an auto originally, and I kept the auto TB when I swapped my engine in. I prefer the auto TB to the manual for a few reasons. First, it feels like it gives smoother spool up/throttle response. There's less of a 'step' between feathering it and full open. I can't say for sure if it decreases spool time (I doubt it does) or how different it is on the stock turbo, but I think if you upgraded your turbo, then the auto TB is a nice partner to the upgrade. It feels like I have more direct control over how much throttle I'm using, and it made autocross a bit nicer (less step = less sudden torque spike). These are just my opinions though

Cool, that tells me what i was looking for.
I'm annoyed by the throttle feel on my car. It's like the first 1/3rd of the pedal is about as far as you can get without hitting positive pressure. Then the feel of the pedal changes, almost like there's a second spring or something, and then if you go any farther than that, you have boost. ALL OF IT.
Autox = useless.
