Batman,
Keep the plates the stock size! Once you port your TB it will flow upwards
of 725-750cfm, which should be fine! Just dont get into the area around the
plates with your boring bar or your idle wont be in range anymore!(with the
stock plates)... remove the ridge or reduce it above the plates, add as
much radius as you can on the inlets and do all of this with the plates and
shaft removed! Youll need to grind the part of the screws that stick
through the shaft off since the threads have been "upset". Then you can
unscrew them and slip the plates out of the shaft. The shaft will then slip
out of the TB if it isnt burred up! I dont reccomend doing much with the
stock shaft unless you re-coat it. Its got an Ecoat on it that prevents
rust and "lubricates" the shaft in the center journal. You can loctite the
screws on re-assembly and remove the upset length to reduce their profile.

Subject: DML: Boring Throttle bodies
> I'm not wanting to step on anyone's toes here, but I've been thinkin'
about actually boring out my own throttle body. I'm wanting to pick one up
at a salvage yard or somethin, I have access to a mill and whatnot. The
problem is the butterflys, I have no idea where I might be able to pick up
plates made for larger throttle bodies, and I'm pretty sure it's a pain to
make new butterflys. I know there's no way I can do better than Quick-D or
any of the other guys out there making bored out throttle bodies, I'm just
one of those guys that likes dinking around with my own stuff and saving a
little money on the side. Anyone else tried doing this kind of thing?
Anyone know where I might be able to get the larger throttle plates?
