Firstly, one has to extract the TB from the car. You'll need a Torx set or a Torx30 to undo the bolts.
Hardest part is removing the throttle cable
I used a big pair of pliers and prised it over the mushroom head holding it in place.
Unclip the throttle sensor cable.
Take the TB to your "workbench"
Tools required....2 part epoxy, sandpaper, Dremmel (mini-drill), suitable Dremmel tools. wet "n" dry, face-mask.
Firstly you need to rough up the outer wall of the TB where it is "indented" with a coarse sandpaper. This gives a good "key" for the epoxy to adhere to.
When satisfied, make up the epoxy and let it cure for a while until it is starting to go off.
Smear the epoxy over the TB, building it up to fill the indentation. Be aware that you working on a curved face and make sure none of the epoxy gets onto the TB butterfly return spring.
When happy that the epoxy is built up enough, more better than less, let it set hard.
With your Dremmel, or equivalent, start to strip away the plastic "lips" which protude in the TB. Do this slowly, a little at a time, taking care not to take too much off in one go. Stop occassionally to clear away shavings and debris, and to make sure all is ok so far.
The idea is to get a smooth inner surface. If you are happy, take a little wet and dry to smooth off the inner wall.
Voila, one ported TB.
