Got bored the other day and ported out the throttle body. Didnt take that long. Bout 45-1hr for each one. then spend another hour with sandpaper smoothing it out.

You ought to get one of those injector spacers. They lift up the injectors a little which helps get more air into the bores. Pretty cheap and might be worth 1 or 2 hp.

should talk to tim about that ****...i knew he had a bunch of tbi TB's machined rather then "home ported" which im sure he would let of his hands real cheap...ive seen them and they look real good..not sure if he sold them all or not.

easiest way to space the injector tower is to just put an extra gasket under it. the hold down screws are long enough to reach through 2 gaskets.

looks like you did a good job. one time i had teh top of a tb shaved flat by a machine shop to save myself time. wasn't really worth it though. 99% of the time is in the rolling of the edge into teh throat anyway.

A dremel was my friend.

Not like there is any noticable difference.
I was planning on putting 93 octane in and seeing if I can squeeze any more timing out of it, but at 2.03 for 87, 2.19 for 89 and 2.29 for 93....regular is going to have to do for now.

i used my dremel a lot too. i always liked to do the finish shaping with sand paper though. once you make a nice edge with a dremel you can make it smooth as glass with wet 800 grit. :)
i still have 3 or 4 tb's here. i have one started that will go to malibu79 when it is done.
the rest of them i will clean, prep, and sell on ebay.
