Here's one write-up on it. You can use a die grinder (if you have access) or a dremel.
Tb Im right where your at right now,and if you go under ls1 throttle bodys,Theres like 3 or 4 companys that will sell you a stock ported TB and charge you a core or send yours with the order and check and they ship out the next day,but while i was on there i saw MTIs TB and fell in love LOL!! It looks and is described like a piece of art and accufab has a really nice unit too and Nx has one with the swirl bult right into the inlet of the TB,Has anybody on here bought are heard anything about the TB i just mentioned,exspecially the MTI one ????? LOL!!! THANKS GUYS and PS ide stay away from the fast myself,My buddys was sticking and he fixed it with a set screw to keep the plate from walking and lightly polished the bore and its fine now but **** **** you gotta fix right out the box LOL!!!
You can buy a stock TB that is ported and polished from a couple of the guys on here (I can't think of their names at the moment) for relatively cheap. Plus they will take your old one for a core
I'm with the majority on this one, just get your stock one ported and polished, bump stop mod couldn't hurt either.
Go to neweraperformanceparts.com (one of the sponsors on the right>>>>>>>)
or PM Matt@New Era for any questions i think its $75 bucks and youll have YOUR TB back and ready to put on in 3 days.

i'm not sure if there a sponcor but a company offers 80mm & 85 mm polished TB's for under $200. i dont know but i wouldnt think you could port a stock TB 75mm all the way upto an 80mm. my 80mm required a spacer to manifold

i am porting mine on my ls1 but i have seen some throttle bodies where the bar that the blade mounts too has been removed on one side and the screws put on directly to the blade is that hard to do to remove that one piece of the bar ?
does it make that big of a difference if you fill in the gap where the air flows into the iac and all that vs just porting it and not filling it in? also, should i knife edge the blade and cut off half the retainer bar and grind the bolts down? i just dont know what is necessary and what isnt.
Port the stocker. I did it, it's a worthwhile mod. There are some good porters around here. Bo White comes to mind first and foremost. Later I upgraded to a 90mm setup, gave my buddy my stock ported one because his fast 78mm took a dump. It would stick shut, and open. Happened to him on the street and at the track several times. He's happy now.
