Finished Porting and Polishing the TB and Y Pipe. Here's some teaser pics. I like, you like? Write up to follow shortly!!!!

Looks like you tried to knife edge the trottle plate. How'd that turn out?

I have to believe that TB is gonna make more power. Nice job!

it;s a work in progress... i was going to take the whole plate out, seems easy enough right? but the screws holding the plate in are aluminum. this is where aluminum's natural thread locking abilities and softness are a terrible combo. Obviously they didn't ever plan on someone needing to take the plate out. the phillips head started to strip, so i stopped, its really soft! i was being very slow and gentle. I'm going to call the local dealership(s) today to see if i can get the throttle plate screws (and possibly a new throttle plate to finagle with ). if so, i will easy out or drill out the screws.

The plate that is in there now i started to knife edge but the clearances to fit my dremel in are too tight. I did the best i could, but i'm not happy. I didn't even try to clean it up.

I'll keep you guys updated and will get to a short write up when i have the whole thing ironed out.

I take it you haven't yet reinstalled this throttle? My guess, from looking at the material removed from the plate, is that you'll have a high idle.

(I speak from experience)

I am assuming that this can be corrected with a tune, and then subsequently be turned into a power gain, however big or small... correct?

i dont understand the purpase of polishing it it's only gonna get gummed up again anyways lol but i did it anywhy with a honing tool and a drill.

I did it because I could pretty much

Nope i haven't installed it yet. The plate that is on there is trash but it still has the stock edge. You are correct about the high idle if i removed too much from the edges of the plate and i already ordered 3 new plates to fool with. Thanks for the heads up.

One i will knife edge with a steep angle and i am going to shoot for keeping the stock edge. I used a permanent marker trick on the y pipe and tb that worked flawlessly. the pipe and body aren't actually any shorter as they both have stock edges.

The other two plates i will keep stock and have one handy just incase i screw it up. i also plan on using hex set screws instead of the phillips heads on the stocker. we'll see though. I'll have to weigh them at work to see if there is a significant weight difference.

the way it's looking now, the best way to keep the stock edge would be to not completely knife edge it like i did on the ypipe and tb. i'll probably polish the plate and rod too just for sh!ts and giggles.

nhluhr did you remove the plate or just grind it still in the body? If you removed it, did i miss something? I wd40ed the little bastards and heated them up. The aluminum is really soft(yes even before being heated)! I'm going to easy out them tomorrow.

BTW guys the throttle bodies arent cheap. I priced them out because i was looking to do a couple core exchanges (ported tbs for stockers+labor&parts) for some people and i was looking to get one started to make the process more efficient. Expect to pay $550 for new one if you screw up. This is a cheap mod that can turn real expensive real fast!

Stick with the y pipe or atleast start with it if you're not sure of your abilities. They're much cheaper. Remember: you can always take more off but you can't put it back on!!!! -End public service announcement.

I'll have a full write up with pics up by tomorrow night.

I don't know about anyone else but the pics i took of my stock tb are of it straight off the car. My tb stays pretty darn clean. I have dual catch cans and an aps cai.

you are probably correct. the aluminum would eventually oxidize and attract dirt and oil (esp if you don't have catch cans). I considered this however and after polishing the body i added a liquid metal polish with anti tarnish protection in it. If anything it is my hope that this will delay the aluminums natural tendency to oxidize and it will keep some of the dirt/oil off.

if it doesn't work, o well. i did polish the y pipe at the beginning of the summer (4k miles ago) and it looked exactly how it did when i installed it(super shiny but not as shiny as the tb). so that says something in itself.

same here. it looks really cool! my pics don't give mine justice. i wish i could take good pics of it. I'll probably use it as a decorative piece until i have to put it back on. maybe i'll serve dip in it for christmas or thanksgiving. all right thats enough sorry.

Sounds like a good plan on keeping the stock edge... It looks like you pretty much did exactly that in the one pictured, but maybe got a little too much and took some of the edge away? Could be wrong, but that's how it appears from the pic.

I didn't remove the plate - I just carefully ground at it while it was in. This was on my 2005. With my 2006, I didn't touch the plate itself, just smoothed the edges inside the tube and knifed the hose inlet. I thought I was not removing much material from the plate but I still ended up with a ~850-900rpm idle speed, so I must have removed some.

Regarding the polishing, I think the general concensus on polishing is that it will help prevent oxidation and buildup. The only place I'm convinced of mirror-polishing being a bad thing is post-injector where a slightly matte texture will help 'tumble' the fuel a bit.

Yeah you're seeing the aftermath of a lot of frustration being taken out on the plate. Like i said it's trash.

you and i sir are on the same page!

[Pitcherman]

I wonder if it wouldn't be better to hand file the plate? Would take longer but seems like it would be much more precise than a dremmel.

[snorky]

that's the plan. good thinking!
