Talking Fabricating FMIC piping..Possibly flipping intake mani. Help :)

Hey guys
I'm ordering a 24x12x3.5" Bell core this weekend and my buddy is welding the tanks on. We're looking to do a little something different with this IC since I hate AC and took it out 10,000 miles ago. I didn't remove the heat exchange, but I'm doing that tommoro after work.
Anyhow, has anyone done an intake manifold flip? I'd like to do it to be 1. different 2. less piping 3.look cool The AC compressor is already out (as well as the lines) and the heat exchange is also on its way out. What else needs to be done? A new 'holder' for the cruise/throttle cables, and I need to relocate the alternator to where the AC was, correct? If anyone has done this or knows how, let me know!
If it takes a week to do this, it'll take a week. I'm going for something unique. I really would like to try and do something similar to the WRC setup, but the core may be a tad large for that

I have seen a car with a reversed manifold and when he flipped it, it would not clear the hood. So he had to cut it and weld another piece onto it to fit. So he had to use 2 intake manifolds. 1 to cut to clear and the other to cut the piece out of to weld to the already hacked intake manifold.

If I remember correctly.

Don't ask me how/what/why, but this is what it looks like. His hood is a custom unit, but it doesn't cause any problems where the throttle body pipe is. Where the Nitrous lines are.....that's another story!

Alex over at I-club did it. Bspec's GC was one of the first to do in the states, but last i heard the car was looking for a new owner.

The pictured above looks like a monster

I saw one done that way at Va. Motorsports Park during the Nopi Nats. last month. It was Easystreet's sti they said its pretty easy to do just a matter of plugging some holes and opening new ones, they're good people give'em a call.

ESX did it? I'll definatly call them.
The more i think about it, the more i think i may just do normal IC. It's going to be pretty mean, since the heat exchange is coming out, I can put a little of an angle on it and probably get airflow across the whole 12", with some of it sticking out near the grille. If I had the money/time/NEEDED a bigger core, i'd like to think i could fit a 14" core in as well with some more fabbing.
I'll keep you guys updated and post pics. If it's really simple, and im not going to have to make all new fuel rails and whatnot, i may do a flipped mani Clearance is a prob too.

On the WRX it will fit fine with the flipped manifold (without modifying the hood) if you remove the AC and put the alternator where the AC used to be. It's really a pretty simple thing to do if you just go with custom piping for the TB. I don't consider it all that worthwhile with most of the turbo placements you see on cars that have it done. Like the one above the turbo outlet piping still winds all around and goes through the right hand foglight area to get to the IC most likely. The piping to make it go around to a rear facing TB would have likely been only marginally longer. With a turbo that big it's just not worth the trouble.

Now if you put the IC up above it makes perfect sense since you can run the all the IC piping in the engine bay alone depending on the turbo placement. You could almost run straight pipes off the turbo and off the IC into the TB, ala the WRC car. Here is a pre-made FMIC that is made for such a setup:

Would a different hood be needed?
That is sort of how I planned on running the IC, since the heat exchange is coming out. I figured with a little tilt on the IC (Top going back about 15degrees) I might be able to squeeze piping over the top and save having to go allll the way around the fog lights. Even if I dont flip the manifold, it would save a headache since I'm fabbing the piping myself w/a friend.
Does the inlet of that IC run the same piping as a normal IC?
Scott

Edit: I see that pipe is also routed differently. If I don't need a different hood, thats most likely the way we'll weld up the tanks
