Aftermarket intake manifolds and vaccume/boost sources

Hey guys long time no *****

I just bought an IDA intake setup for my TII and I want to know how all you guys with aftermarket manifolds and custom setups get vaccume sources for your fuel reg's and all the other things like wastegates and bovs. From the looks of it my manifolds aren't setup with nipples for vac lines. Is there a way to add them to it? I haven't gotten the parts in the mail as I just bought them off of ebay but from what I can tell the LIM is made of aluminum. This is all going to be run by a microtech also in case anyone wanted to know.

u can always weld on some bungs..or (gettto way) just drill a hole and use a grommet and stick a hose with some type of stiff adapter in the hole!

EDIT:
I did the a similar thing (getto way) on my TII...I was looking for a constant vac source so I jammed the stock 1way valve(the one that goes into the intake tube after the AFM) into the silicone connector and it workes just fine!!!

I have no idea what you can do to solve your problem...

Question: What are you doing for an air filter?

I have two options: Buy an aluminum plenum from tweakit or make my own.

Drill and tap the cast bosses on the inside of the manifold directly under the throttles, and install brass hose barbs. Do the same thing to the bigger boss on the outside of the manifold under the rear throttle for the brake booster line.

Yeah.... You drill a hole... Lube it up... then insert the tapping device... Tighter the fit the better.

Hehe now that really didn't sound right....

tapping is easy, the set will come with a variety of taps, and the handle to screw them in with.. depending on what diameter/coursness of thread you are tapping, the instructions will indicate the right size drill bit to use.. but yea use those bosses, theyre probably designed for nitrous nozzles but vacuum nipples will work too. you can always use a few t's if you dont wanna fill your manifold with holes.. also make sure you clean it out good after the drilling.. brake parts cleaner works nice.

always remember to drill a smaller hole than the tap, not the same size. Oiling helps make a cleaner thread, and bring the tool back out every turn or so to empty the shavings. I would probably practice a couple times on similar surfaces as to keep that intake pretty.

Well the LIM for the setup is only 179+ shipping so if I completly destroy it it isn't tooo much money lost. I may practice on my spare S4 UIM

Yea you want to turn the tap 1/4 to 1/2 a turn, then back off a bit, then another 1/4 or 1/2 turn. Its kinda tedious but its really easy. As long as you take it slow. You want to back out and get the shavings out too, as stated above, they could wreck the threads. Just dont put it in, and turn it as fast as possible to get through it, not a good idea at all.

575 shipped. I opted for the "buy it now" on ebay. I didn't want to deal with opposing bidders messing with my ****.

My bad my math sucks ***. I payed 565 shipped. It was 550 "buy it now" and 15 for shipping. For some reason I added that up to 575.


In any case thats way better than buying from TWM or Tweakit.

EDIT: I added the parts up from www.tweakit.net and it totals up to 812+ shipping. And mine are comming with a custom TPS setup for EMS's so thats a little added value.
