Has anybody tried to hand port the throttle body for a 3800 series II. I've heard of it being done and wanted to know how.

If you look into this month's edition of GM High Tech Magazine, it has an article on free hp for an LT1, and it shows an indepth procedure of TB Porting. Not the same...I know, but it'll give you an idea on how to take the on the project. I have an extra TB for my 3.8 in my garage, so I'm thinking of trying it out. Keyword: "Thinking"

Search, it's been done, and it either cost a lot to get the car running properly... or... cheap and the car ran like crap until more money was put into it.
At least that was the general consensus of what I read.AIM: escalier deverre<br />\'02 Pearl Blue Metallic RSX-S (daily driver)<br />\'98 Black Firebird<br />98 V6 turbocharged to 02 LS1 swap<br />\'02 LS1/4L60E<br />LS6 Block, LS6 Intake Manifold, Thunder Racing 215/220 .600/.523/115 Cam, Titanium Retainers, Crane Double Valve Springs, 125 shot NX Wet Kit w/ NOS brand Purge, True Dual \"H\" Pipe w/ two chambers and dumps, 17x11(rear) and 17x9.5(front) Black Powdercoated ZR1 Replicas on 315 and 275 BFGoodrich Comp T/A\'s (Street)/ET Drags/Skinnies on Weldlites(Track), 3.42/LSD

I've done it and seen good results. I wrote up a how-to but this method has seen a lot of flack, if you mess it up it will run like crap.

If you have a 98 or below, porting is an option. If you have a 99+, there is not really anything in there to port, except a little flat spot where the pcv opening is.
So let's say you're talking about a 98 and below. If you take just the bottom half of the maf sensor post out, it's not too bad. Might need a maft to true it up.
If you take the entire post out, you will need to get a 99+ maf sensor for it, and rebore the maf sensor opening so the 99 will fit in it. The 99+ sensor takes up about as much room as the upper half of the post on the stock 98 and down...

I did it, took the bottom part of the maf sensor post out and everything. Remember to leave the plate behind the maf sensor in. Just cutoff the bottom part of it and put it on there.
My car ran like crap for little while and now it runs normal now. Dont feel much difference in performance though.1997 Camaro Y87. Turbo.<br /><a href=\"http://pureoctaneracing.net/\" target=\"_blank\">Pure Octane Racing</a>
