Never used it. I ported it to prove that plastic could be polished. Took me all of a half hour to shave the ribs off and smooth the lip a bit.

^^that actually looks really good. I wonder if it makes any difference in power

^^Pretty much what mine looked liked, but holy cow that is polished lol. Mine wasn't no where near that finish. It helped with throttle response and was free though. But it's no where what a real tb gives, it's more like a medium in response. Quicker stock feeling but not a aftermarket tb feeling ether.

thanks for the pics. I was reading on another site and they said you could shave that oval to a circle and shaping it with epoxy?? not sure what they mean by that.

I like the way the stock ported throttle body feels. It costs 3 bucks and takes a half hour to do, and it feels better for a DD than my bbk 65mm tb felt. I hated that piece of shit.

When you open up the stock tb, you will actually tunnel through the plastic and there will be a hole. Epoxy (jbweld) is applied before grinding is started, and it adds more material so you don't bore through it. You'll understand when you hold it in your hand.

^so your putting the epoxy to fill that hole in the tb shown above? I just dont want to have to buy another tb if i screw up.

Epoxy is basically jb weld? If so you use the quick setting stuff I assume.

 

[sleepyboy]

No don't fill the hole on the inside. Your going to fill the hole your going to make by making it completely round. You'll understand once you get it in your hands.

I hope so, thanks guys

There is a valley in the plastic on the outside of the throttle body, you are filling that with jbweld. Its so hard to explain.

I recently did my zx2's TB it's aluminum though. The car seems to have droped by about 150ish RPM's on highway at 70mph. You can also remove the butterfly and cut the shaft down I have pics I have to upload still from my phone. The most naticable diffrence was just smothing it all out the butterfly part made little difference but some.

 

[sleepyboy]

You'll feel better tip in mainly.

Really the zx2's are metal, cool

Ya metal no plastic junk. Took a carbite bit, grinding stone then a flapper to it. You do make a hole in 1 spot and use JB weld. On your plastic ones you want 2 part plastic epoxy not jb weld.

Also my car was a dog with the AC on now it dosen't seem to notice that it's on. I used to have to turn the AC off to leave a stop light. Not now.

A friend of mine picked up some clay type mold epoxy to use for plastic parts like pvc pipes etc. I guess that will work. I'm doing it tomorrow so I'll let you guys know how it turned out.

 

[bradmra]

ported it today, there were no fins on my tb, but it was very easy to port it. I didnt even grind through the plastic and was able to still make a complete circle, I'm proud of myself lol.

for a little more cfm you can remove the tps sensor and butterfly. remove the shaft and cut the top of the shaft off. then grind the screws shorter.then reassemble centering the plate and using loctight on the screws. I did this to mine. but found most of the difference from the enlarging the bore very little from the butterfly mod but still some.
