I did my own TB work and got quite aggressive with it
which turned out very good. I used a hacksaw to remove the
wings over the bores, air grinder for finish work and breaking
the angle on the bores. For the throttle body blades and shaft
I used a bench top grinder and some new recessed screws (Stainless)
from hardware store. All in all took about 3 hours which having
never done it before went well. I then proceeded to polish the entire
TB top and bores with fine sand paper and then finishing off with metal
polish. Looks very hot- glossy polished aluminum.
You can probably get away without the air grinder but a dremel
is a bit weak and will add time needed to grind. But definitely
use a hacksaw to remove the wings on the bore. Takes about
5 minutes instead of trying to grind them off.

Subject: DML: Advice:Tools needed for TB Work....
I need to make a list of items I will need to do some work on my TB, and
think my fellow DMLers can help. I have researched all the websites, posts,
and write-ups on homebrew TB porting/polishing. I will not being doing at
all
any major changes in my throttle body, just some simple and hopefully
effective changes. Here is what I plan to do, along with some questions.
I have a multi-speed Dremel, and really any/all other tools needed to do
this. What bits will I need to do this. I noticed in Summit they sell a
"Porting and Polishing Kit" for $30, is this something I should invest in
for
this TB mod? It appears to have alot of bits and attachments, but once again
I am not sure on what I will really need. Here is what I plan on doing:
I first will remove the air filter hat bolt and hardware. I see where
this bracket ontop of the TB, between the two bores, could create some flow
problems. I will also create my own "S-Bolt" whick will completely eminate
this restrictive bracket. If I need to bend some rod to make this bolt, I
will of course cooling it down with oil and not water(thanks for the tip
Bernd!!!)
Next, I will remove those tall ridges on the top of each bore, and grind
them down flush with the top of the TB. I want to also create almost a
gradual entrance effect for the air coming into the bored, so the tops will
be rounded off. I will clean up the area around where the old bolt bracket
was, smoothing it out.
I am really not sure if I should touch the throttle plates/throttle
shaft, because I am not sure really how I would go about making them
thinner,
and doing a good job at it. I know countersunk allen head screws for the
thottle plates are popular, just dont know about messing around with them
yet. Also, I dont want to really touch the bores, other that just polishing
them up a bit, from the thottle plates up, nothing under them. I might even
splurge for 4 TB bolts that don't have as tall of heads on them, almost
countersunk bolts I guess. So, does is this ok for a fairly mild TB job?
Anything else I might want to consider? Thanks alot in advance.
