Boring the INlet to the IM

Can i do this before i get the throttle body , And just have the inlet ready and 60mm , for the 60 mm i am getting and still keep the stock on there , and run it the same? Or will it mess up any thing? Im thinking it will disrupt the air flow but i dont know..

I don't see why it would make any difference. The old TB will still fit fine. You won't get any performance from just that obviously but if you want to get a head start then I don't see why not.

Yeah i was just making sure , Because , People where getting on me about how i should just wait till i get the tb ... but im just going to take the whole IM off Flapper it , And then paint the IM Black and then paint the Cover red. Since the screws on the cover are stripped , And i would like to take out the im , So i can do a much better job , Any thing to look out for while taking the im off? Is there any special locks , The other day i was going to take off the TB but decided not to because i was trying to use an allen wrench not a power tool with an allen tip on it , I have a power tool today and ill try it now.

I would be very careful with a power tool to remove it. It may come off easier, but it also will strip a lot easier if you aren't careful. Just a warning. The problem is that if the cover won't come off, you aren't gonna be able to get at the bolts that are holding the plenum to the manifold, as they are underneath the cover. That cover is gonna have to come off first.

He's not trying to take off the Intake plenum, just bore out the intake inlet where the throttlebody is connected to.

I just want to make sure you're talking about the cover that says 3000 on it right? If so then yes there are bolts underneath that cover. Like in the previous thread, you're gonna need an extractor set to get those screws out of the cover to get at them. You could bore out the plenum with it on there still, just stuff a rag into the plenum and carefully bore it making sure to get all the shavings. The only advice I can give on the TB screws is soak them in some PB blaster or similar and use some elbow grease. Wish I could be of more help.

Yeah do the best you can to clean up the black sludge. WD-40 might work or any other lubricant. When you start boring out the plenum BE VERY CAREFUL NOT TO LET THE METAL SHAVINGS IN. Stuff a rag in there and you might want to wet it and the area around it to kind of catch the shavings. Stick a vacuum in there after to make absolutely sure.

The black sludge is carbon deposits. Try your best to clean it out. I did it with a rag. I didnt do the best job but it got most of it clean. Itll give you better throttle response feel. I would first take the TB off and do the boring first. Make sure the rag is in there so no metal shavings get in the engine. After you are done pull the rag out and make sure no shavings are in there. Id say at that point clean it out. I used some TB cleaner or somethin'. Cant remember.

You don't really need a flapper wheel, you can just use a metal file to expand the inlet. Just extend the current inlet to 60mm and mark it off and carefully file it to the correct size.

You could try it with that, but just be careful not to go to crazy. 60mm is all you need.

If it were me, I would just to make absolutely sure. It would also give you the chance to paint and clean better also. If the pieces were small enough it probably wouldn't do any damage, but it's your call. I say better safe than sorry.

well i fineally got the 2 screws i couldent get out off of the IM Cover , Whew it took me all day , The first one came out like a charm , What i did since the screw extractors where not working was took a drill , And just drilled about the size of the screw and bam the top broke off , Of the screw , Now the second one , Took me about 3 hours , That one i had a little trouble with , And i had to make the hole on the IM cover bigger , Not much bigger but bigger so i could just leave the screw in there , And pull the IM cover over it , Here are a couple pictures. Tommarow i will remove the IM and clean as much as of it i can , And paint it black.


Im cover before i took it off Notice the top middle screw and the bottem left screw. They are stripped.




And here is the tb any thing i will need to do once i put the stanza one on , Will it be a direct fit , Meaning every thing will go onto it?

great day man....you are going thru a lot. What you bought from sears is a wire brush, what I use was a flapper wheel...its actually sand paper and hooks to a power drill. As for the IM cover (3000 thing), if you just had an impact screw driver with the right bit they would come right out. When you hit the top of the screw driver, it turns to loosen the screws. Once you have done this you are down to the allan heads bolts in the plenum. Just get the allen keys that are already on socket fittings...they come out very easy. As for which way to turn the TB bolts, you turn them to the left (counter clockwise). Again just use the allan keys that are on socket fittings and they come right out.
