So i have a potential "First World Problem."
The Escort is getting ITBs.
I'm not entirely sure they'll fit under the hood.
Obviously, autocrosses are not cancelled for rain.
Suggestions? Forward facing scoop? Cowl?
In the event that they DO fit, do i do anything to try and get the coldest air possible to them? If so, what?
What throttle bodies are you using? There may be an off the shelf plenum available that fits right on to them so you can run air ducts.

Gixxer 1000s.
That would be an idea i like if they actually fit under the hood. I'm a little worried they won't... the setup is about 7.5" tall with some REALLY short stacks at the moment. I have a feeling i might want a longer setup.
Hood bulge(s)? Curved trumpets? 
I'm off to find the pictures you posted of the intake setup.
I'd be most worried about proper fueling
but maybe it's not as bad as I assume
do ITBs that are just slapped on present significant gains?
Apparently the stacks were added at some point between the owner who first built them and my purchase.
Here's an old pic of the setup. Notice this car is running a cowl hood.

Tell me more about your fueling worries?
Well, i can't really "just slap it on," this stuff will never run with stock electronics. But yes.... large gains compared to even the gutted and ported KLZE manifold i was previously going to use. Also: Throttle response
There used to be an awesome log manifold made by CZT that was producing ridiculous gains without the finicky nature of ITBs, but that thing is impossible to find these days and goes for more than i paid for this ITB setup.
Get a cowl hood for your escort?
That V8 probably sits a bit higher in the engine bay, though, yeah? (hence cowl)
See if you can dig up the website with the MC-engine-swapped Miata. The guy posted here a little while back, about his aluminium exhaust.
Anyway, I completely forget the name of the shop doing the build, but they had some creative solutions to making the ITBs and air intake clear the stock hood. Completely different application and all that, I know, but still.

That's a V6. Same engine i'm using in the Escort. 
That set of ITBs on that car is the very same set i have coming.

I'm not against that idea... but would like to avoid if at all possible. I'm ok with hacking up a stock hood, but was planning to use a CF hood, and i don't really trust myself to start messing with that.
V6, rather.
Didn't realise you were also using a V6, though. Was wondering what you were going to do with two sets of 3 
.
They really are some short stacks. I've never been under the hood of an Escort, but I'm willing to bet that a bit of a hood bulge and a plenum over the velocity stacks will get you where you need to be and keep stuff out of your engine.
If you were starting from scratch it would probably be easier to fit a cross-ram type setup, but since these are ready to go and proven to work that would be dumb.
Do you think something like that would clear or is going to be wicked close to the setup as it sits?

Yep, they are really short... The funny thing is... if you look at the miata, he didn't even run stacks at all.
I'm thinking it would probably fit under the hood, the more i look at it. The setup is 7.5" tall, and i'm pretty sure the stock manifold is about that if not more.
I think the bigger question at hand will be air delivery.
Clearance will be an issue if i want longer stacks, which i feel that i very well might down the road.
That said, i'm not particularly worried about low end. No matter how i slice it, a worked KLZE in a 2100lb car is going to have more low end ass to it than a stock 300k mile BP in a 2400lb car did.

Those look like they might be even taller.... don't see that clearing the hood.
Add in that i'm FWD, and it gets real interesting.
Maybe that style... but with both sets facing backwards and a cowl...
If you came up with something like the velocity stacks on the m3 above, you could still add two plenum and whatever duct-work you need to get the cold air to them. I have no concept of how much room is available. I don't think I've ever touched an Escort.
You can turn them as needed though. I'm just thinking that stacks of that design are the simplest was to get the longer intake tract without redesigning how the itbs are mounted.

Not the greatest picture to illustrate clearance....
But here's this V6 in a BG:
And here's a stock BP in a BG:
Maybe I'm dumb, but what does something like that bimmer do for air filtration? Is it just for show and dyno pulls?
Are you going to use a plenum over the ITBs? If so you should be able to just run a MAF
If not, you can't run a MAF, and your map signal is going to look like this
you could use a vacuum canister/restrictor to smooth it out I suppose
Or find an ECU that will sample MAP at specific crankshaft angle
The only other option is alpha N or blended tables

A standalone is happening either way.... just remains to be seen if it's going to be Haltech or Megasquirt.
Unless i can find something that fits easily and somewhat cheaply, a plenum is not REAL likely.

What I've read has lead me to understand vacuum blocks are all you need stabilize the map signal. I've not gotten around to testing this information first hand though.
I had a decent MAP signal on my 4AGE (GSXR600 ITB's). The issue is the fueling requirements between cruise (94kPa at my altitude) and WOT (96kPa) was impossible to tune.
I want Alpha-N, and it was SO much easier to tune and drive and live with.
do some research into helmholtz intake tuning. See what your engine wants, and then see how best you can do it

What is Alpha-N, exactly? I'm new to ITBs.
Does it help at all that it's running Gixxer 1000 injectors?
