I thought the Evo came setup with the IAT ready to go with the stock computer; the 4 Bar was only what was needed.
Am I incorrect here? (Looking forward to MAP soonish also.)
Or ... is the stock IAT sensor located in the MAF unit, and needs to be effectively moved closer to the TB? BTW, would the IAT work better inside the manifold or just before it?

Like this.
As opposed to this.
Closed element.
Factory IAT is in the MAF, The GM IAT will work the same in either location before or after the TB.
For the best results use a new sensor, It is possible to use the fuel temp sensor in place of the IAT but the results won't be as good. As for wiring the GM sensor you have two options..the factory IAT input or hi-jack the Fuel temp sensor input, Mine is wired through the Fuel temp circuit(evo 8 ECU pin 77)since I was logging MAT before SD was available. While I'm thinking of it, you DO NOT need to be on any sort of tephra ROM to run SD.
That harness is cute but a waste of money

Josh what do think about installing the sensor somewhere inside the main plenum of the Stock intake manifold? I was going to drill is and weld a bung to it and possibly install it on the bottom side of the manifold for a clean look.
Oh and do you know if the stock ECU can be tuned and pass Emission with the EGR block off and not installed? I would like to delete my EGR all together, but I would still need it to pass emission with the ECU. Can it be done?

Installation in the plenum is fine, some people believe heat soak is an issue, however, GM installs these sensors in the manifold so they are probably designed for it. My IAT is in the plenum & haven't really had any issues...'05-'06 model years have a boss next to the MAP sensor that can be drilled & tapped. Yes, you can run no EGR & still pass.

Have you have done this on any cars like tuned for it when they deleted it?
Ya that is what I am going to do
I just ordered my Omni 4 bar sensor so just need to get the GM IAT one coming. Dustin are you going to be ordering one soon or want me to go ahead and order some? I was going to order a few anyhow and I was just waiting for you to get back with me on your price you can get them for
another couple questions with SD setup. i'm doing new IC piping and intake also. still using the stock bov, it will go between the upper IC pipe and intake like how it currently is, with the vacuum port to the IM.
1) do i need to (or 'should' i) have the 3 port BCS vent to atmosphere or should i add a port to go to the intake like how it currently is?
2) the vacuum line going from the intake mani to the intake, same thing, do i need it/should i put the port on the intake or just cap the port on the IM?

Hey guys, I'm wanting to get back into an Evo IX but there are rarely any listed locally.
I check cars, autotrader and KSL daily. Anyone know of any 9's for sale or considering a sale?
Thanks

Any evo owners want to trade some Evo seats for a vintage 1979 Moped with roughly 300 original miles? I was thinking about selling it to buy some seats but thought I would just toss the trade idea out to the local guys before selling the moped. Moped runs fantastic by the way. 1979 Columbia Commuter.

Do you mean valve cover to intake?
my new wheels will be here next week for my m3 http://www.klutchwheels.com/gallery/sl14-silver
There available in evo bolt patterns too and offsets from -15 to 45...18x9.5
Wheels have only been available for a month or two and I know where to get them for a good deal

Nice wheels!
Wish they had ether of those available in a 17x9 for my M3 
O well. So are you still interested in picking up that one thing from me Wes? If not I think I am going to post it for sale so I can finish the turbo M Project. 
Oh did I just say that

Yea I'm trying Dallin I just had to buy a dr vanos stage 1 vanos over night ship to Vesko because my cousin was driving car down to me and it had to be done. Just have to see where finances are after I get tires on the new wheels(depends on if I have to buy any) if not I'm trying to talk my friend Steve about purchasing, his lazy *** is the one that hasn't taken pictures of the 35r ams kit yet. We can't find the turbo just everything else
