A completely different kind of project.
I bought a TBSS intake from a member here and was looking at my options for a TB. I decided that because my truck will only see warm weather and a perfect idle in all conditions doesn't really matter to a summer/track toy I am going to try to build my own TB. Omitting a IAC makes a TB extremely simple. Well.......
Holly ****!!!!!!!!!!!!!!!! It almost looks like a TB.
The butterfly is being cut at a machine shop and if they charge me it will possibly be the only cost.(I don't think they will but a $10 dollar tip if they don't). I know the tube is a bit heavy material but it is free and works perfectly. 3.5"(almost exactly 90mm) and that is virtually the same size as the intake opening(intake is slightly larger) and the outside is 4" so it matches all the other parts of the intake.
I used the end of a 20mm socket to help support the spring and a small part of a 23mm socket will be the pedestal for the TPS. I need to trim it to proper length and weld ears on it to drill and tap them to fasten the TPS. I still need to make a 0 and 100% throttle stop and like I said I will incorporate an idle screw into the 0% stop just like the factory has. Lastly I need to cut and drill a plate to mount and seal it to the intake. I have around 30 minutes or less into it and maybe another 30-60 min to finish. Obviously I need to clean up the ends of the tube and maybe shorten it just to save some weight, I think I can take .5 inches off of each end. I just wanted to make sure the butterfly didn't stick out past the TB.

Hope it doesnt turn out like your bedcover, your crooked bed, your side pipes, or your back up camera install(all those were HACK JOBs) Sorry, just my opinion. One other thing, it looks like steel to me, have you thought about heat soak at all, the aluminum TBs dissipate heat at a much higher rate than steel, and then there is the safety issue as well. Wouldnt take much to bind up the throttle blade.

I have made a lot of stuff, but I would never think about making this. It just seems like too many problems. I run a 1700 cfm tbody on my Chevelle, and that is enough for any street power I can think of. I wouldn't want the risk of something sticking. I wish you the best of luck with it though.
