Re: Bored throttle body
There is some guy over on alt.jeep-l I think that has been trying to
unload one of those for a while now.
I have seen a few for sale, so many it implies the mod doesn't work for
---- so people try it then realize they have ruined a TB so they try to
find some other sucker to buy it when they go back to stock.

The thing about that mod is some folks with 4bangers try a bored over
4.0 throttle body. That only winds up causing a real touchy pedal
with a huge flatspot at the top.
Basically you can't flow any more air than the engine will use and
if you reduce restrictions in the intake you need to do the same to
the exhaust. It's valid but usually paired with engine mods that
require more air, like super/turbocharging or stroking.

Re: Bored throttle body
Hi Doug,
With carburetors when we increase the venturi area, we must
increase the jet size, I would be surprised if the computer could
compensate without being reprogramed. Your admission of a dead spot
tells me the stock injectors and computer can't handle less vacuum.
