Upon installing my SLP Airlid that arrived after work today, I discovered that my "one owner, stock" 99 Z28 I bought last month isn't so "stock". The previous owner had done the free ram air mod and made a terrible attempt at porting the throttle body. The TB looks more or less scratched in a couple of areas, mainly the bottom center section. My question is, can I mess it up if I go back and try to "re-port" the TB, but take my time to do it evenly and cleaner? From what I see, as long as I don't take off too much it should be fine, but I want some confirmation before I take a chance. Thanks in advance.

 

Sure you can go in and touch it up. Keep in mind surface finish is NOT important at all. A polished finish is not necessary for good flow. Just knock down the lip close to the blade, but don't mess up the sealing surface where the blade rides.

Thanks for the response. It's one of those things that's not really hurting anything I guess, but I saw it, and now I gotta fix it lol. I hate when people half-@$$ things. I don't, and I don't want my car to make it look like I do. I'm not gonna be in a big hurry or anything, but I'd like to clean it up a bit. He just scarred the inside of the tb pretty much, and the MAF housing, and left little tiny nicks in the metal. Not the end of the world, but I don't like it.

 

Yeah, i did home porting on mine and put a buffer to it to smooth all of it out. Its very smooth to the touch, but its a bit uneven in places, so it doesnt have the prettest reflection:



Its kinda hte same thing with my car. I thought I was buying an unmolested car.. When I started to do all the free mods I found out that every one had been done, including !CAGS and cutting te egr tube. Then after getting in the trunk for the 30th time i found a fuel shutoff valve inderneath where the cd changer would be.
