Ok, I don't even Know where to begin, I am in the process of putting a 5.7 hemi in my 72 dart/scamp with a S480 turbo.
Everyone has seen these write ups and articles in the magazine about junk yard 5.7 hemi boosted makes ***HP…… awesome and sounds like fun right, not so much…… as Ray a great friend of mine (SixPackgut) and I found out last night growing gray hairs its more than just that.
You don’t ever see them putting these motors in cars and the wild exhaust is run however which way it could run to connect while sitting on an Engine Dyno.
Note if this was not a BOOSTED application then there wouldn’t be a problem at all and fits really good.
My experience: 5.7 hemi out of 03 Ram. (Also trying to run Exhaust Forward to connect to turbo) The SRT manifolds are too BIG AND BULKY with or without a Tubular front end…. No room (ZERO)
Also Engine/motor plate isn’t going to happen….
Now there is the option of spending $2k+ on a set of custom headers. Last plan….and I mean VERY LAST OPTION for me
So I took the stock truck manifolds and swapped them to the opposite side of the engine, (the ports will line up as long as you don’t flip the manifolds from top to bottom (Upside down) with the stock heads the two center ports bolts will not line up (can get them drilled) the driver’s side manifold comes out straight out as the passenger side has a kick to it going away from the motor towards the frame. With using the spooled type mounts made for the gen3 hemi the passenger side motor mount is bolted and gets in the way of the oil filter so that has to be relocated, (not a problem if this was not a boosted motor and exhaust manifolds where ran the other way) but the passenger side manifold runs very close to the where the 2 oil fittings are going to be ran to do a remote oil system.
I will be trying to set the motor into place to even see if this will work in the next couple of days. But this looks like the closes thing to making this work. I will get pictures soon to show a little better of how tight and no room there is.
*****NOTE TO SELF this isn’t a LS going into a mustang, this is an Over grown Elephant trying to fit into a trashcan.
I hope this HELPS..... and I will try to keep this updated
Thanks.
Please chime in on this, input,pics, suggestions.....

I hope yall can figure something out. I'm sure it'll fly when yall get done w/ it. This is why I like nitrous.  Everyone keeps saying I need to turbo my car, but the motor barely fits in there like it is, lol. Much easier to hang some solenoids and put a bottle in the trunk. Then again, I'm happy being overweight and slow too, so... If I can help out in any way, just give me a call.  How would a set of upside down shorty headers fit?

Lol chip, First time I saw your car I was dumb founded about how tight it was in there.....crazy! and yes your car is over weight but the car isnt slow one bit. 
The shorty headers wouldn't work because the heads are at such a angle they bolt more on the bottom than the side.
Thanks Chip

OK, I knew they bolted up kinda from the bottom like my Gen2 does. I wasn't sure how wide the motor is and how much room is at the inner fenders. Now that I look at the pics a little better, I don't reckon a shorty has a chance of clearing.
If I think of anything else that won't work, I'll let you know.

cut the factory flange off the manifolds and weld on v-band clamps
be prepared to cut up the engine compartment was looking at this option on big block a-body but decided against for space and didn't want to cut up a factory big block car
yeah I can't imagine doing a turbo anything w/o some   and 
have aftermarket "rack" style k-frames come down in price yet?

yes, it might  the biggest problem is the Steering shaft,grear box,and the inner fenders  . I will know more when I set the motor down in there.

Just a question, why not just run a centrifical blower and a motor plate?
Then it is just cold side plumbing, off the shelf headers, etc
You could do a remote water pump and free up some room, use the multi rib serpentine balancer to drive it and a alternator.

You don't have to run the oil lines there. You can use a regular ole remote filter adapter and screw it to the oil filter pad. Those block off plates are only necessary when using spool engine mounts.

Admittedly I do not have an A-body, but an Early B-body is also pretty narrow. My stock magnum small block manifolds exit in nearly the EXACT same spot as the hemi manifolds. They kick outward towards the frame rail with both motors. Small block is in the car and running, Hemi has already been mocked up for potential future replacement. Just take your time, and plan out your hot side routing carefully... you'll be able to make it fit... By the way... if it makes you feel any better, you're not dealing with any specific hemi problems... you're just dealing with general TURBO fabrication issues!

there are a few ls turbo swaps where they used a rear facing drivers side manifold looped the exhaust down like a normal y-pipe but brought it up and into the back of a forward facing manifold on the passenger side
This has been my thought also, not gonna jump to the extreme until I see the fit mit with motor in there.

Ditch them and make your own. Those lines and that block off plate are way more of a headache than just ditching the spool mount trust me. Better yet, just swap K members to a non spool K.

Great post. I've been kicking around the idea of this swap and suspected it would be as bad as what you've run into. Unfortunately it looks like I'll have to just run an LS engine if I want a turbo in my Demon to avoid the headaches. It's a damn shame the Gen 3 hemi is so wide. I'd turbo the Gen 2 hemi in my car now if I could make it all fit. I'm already using a GM trans and Ford rear so my cars already a mutt.
why don't you just turbo a Magnum? I mean how much power do you want? Boost makes stupid power no matter the block.

LS is lighter w/high flowing factory heads and many will argue capable of much more abuse. There are many running 800+ HP with pretty much stock, high-mileage long blocks.

No doubt about that...and the same could be said with the LS vs. Gen 3 comparison too. But to Yuck's point... how much power do you need? If you're looking for sub 700hp, just about anything will work with a turbo.

Here are my mounts that adapt a non spool /6 K member. This could be configured different for more manifold room too. I can run the oil filter in stock location with this setup. Point is there are other ways to mount these things than spool swap mounts that IMO take up way to much realistate.

Dustin, they look like they might interfere with steering column. Not sure, if you get them I would love to know. they will have the d shape port too. crap, I want to buy them

Durango/Aspen are another possibility, and they can be had in Eagle port size.

I hear you. I'm not new to turbos. I built a turbo setup for the 440 in my 69 dart. I still have that engine and turbo setup that I could drop in my car, but I'd like something smaller and lighter. The low cost of the LS and available turbo exhaust is appealing to me. If I break it, I can simply pull another one from the yard for $350. I can't do that with my 440, which I believe is weaker than the LS anyways.

Looks like the passenger side Durango/Aspen manifolds are the same as trucks. The drivers side are unique however. Here is an eBay item number of a driver's side Durango. 321405360723 check it out for yourself.

I ran into the same issues with my Dart. I wound up building my own headers. I work at a dealer and scoped out or tried on every possible factory manifold.....no way. So I cut the flanges off of a $100 set of headers I had and ordered a 1 3/4 header kit from Summit ($120) along with some V-bands and went to work. This was the first set of headers I have ever done. It took me about two weeks on and off to do them. The turned out pretty good (I think). There is simply no room on the drivers side for any other option. Take a look at my photobucket album. Take your time and plan ahead. Dave http://s1083.photobucket.com/user/swinger440/slideshow/

^^^^^^ Do you have a Pic of those on the block?
i will, i have them on my mock up block on an engine stand. i plan on documenting this process a lot with pics. i think with mild mod to the headers, they will work well on my build. i am making a bracket to move my alt. up and out 1 inch.
an a/c compressor is most likely out of the question. my hot side will run to the front even with the oil pan rail under alt. and between oil filter adapter and frame then s up to turbo on pass. side up by radiator..
the driver side will run up pan rail where a/c comp. goes, then around belt, then 90* turn in front of balancer up to same turbo 
my hot side will be 2.25 stainless with a flex pipe on each bank . the downpipe will run parallel with valve cover between VP and inner fender turned down to follow trans. dip stick tube to under the car

i will, i have them on my mock up block on an engine stand. i plan on documenting this process a lot with pics. i think with mild mod to the headers, they will work well on my build. i am making a bracket to move my alt. up and out 1 inch.
an a/c compressor is most likely out of the question. my hot side will run to the front even with the oil pan rail under alt. and between oil filter adapter and frame then s up to turbo on pass. side up by radiator..
the driver side will run up pan rail where a/c comp. goes, then around belt, then 90* turn in front of balancer up to same turbo
my hot side will be 2.25 stainless with a flex pipe on each bank . the downpipe will run parallel with valve cover between VP and inner fender turned down to follow trans. dip stick tube to under the car
also remember, i have rack/pinion tube front end with home made mounts
