One of the 94-95 guys did it. It should work on a Fox, although the intake system may be a bit different.

I think that's a bit excessive, but it'd work!

haha i was thinking of the same one..
on a more serious note, i doubt it would work well without running a fuel cell since the oem tank is so large.

thanks, very interesting thread. think Im gonna try to setup a single turbo, not to big either. I have @ 300-320 rwhp right now, like to get like 400-420 rwhp, but with a real wide and torquey powerband. I think thats a pretty realistic goal. once I sell my streetbike I'll have like 2 G's to put towards it, thnk most of the cost will be the fuel system and tuning.
My buddy built up a home made twin rear set up with his 351W powered '82 GT. Went pretty good. engine had nothing more than an E-cam, ported E7TE's and Performer intake and under boost it ran 11.20's@117mph. 
You'd honestly be better served keeping it in the engine compartment, for ease of installation if nothing more. Put it in the driver's front corner, run it through the intercooler and right up into the intake on the passenger's side. I can understand if you're going for the hidden look of the remote mount setup, but aside from that, it doesn't have much benefit. You can buy U bends and header flanges from Jegs, or Summit and make up your own hot side with fairly relative ease, if you're mechanically inclined enough and know how to weld.
I wouldn't say it didn't offer "much benefit" The rear mounting cuts the otherwise pistol hot under hood temps considerably compared to an under hood set up. Not to mention it keeps the additional 60+lbs of weight out back, closer to the rear wheels instead of over top of the K-member where you want it the least. The ACT's dissipate several degrees during the trip from the back, to the front of the car as well.
I wasn't a big fan of the rear mount set up initially as well, but as far as pro's vs. con's, it doesn't seem so bad.
Not to mention it leaves plenty of room in the engine bay for the components of a second power adder for those looking to make some serious street power.

pics by any change?
I'll Email him and see if he's still got some pics of the system. He's since disassembled it and sold the car.
He's one of those guys that gets bored quickly. His current project is a Mazda RX7 with a warmed over 5.0L HO under the hood.
....personally, I think he was better off with his Mustang.

i love a 5.0 , 350sb or a lsx swapped FC RX7 lol. almost had a chance to buy a 89 rx7 with a 302 in it, but dude was too far away.
It seems like a rear mount system would have slow throttle response issues and possibly make lag more of an issue... But I can't say I know a lot about rear mount turbos, so don't quote me on that. 
Also, it seems like routing the intake tubes under the car would definitely be a PITA.

Negative, i was in a 800rwhp newer GTO with twins on it, and that thing had less turbo lag than my old 265hp WRX. If they are set up right, just like any other turbo setup then there is little to no lag. It is easy to assume there would be more lag with more piping, but it wasnt the case at all.
That car was fricken BA, 408 LS motor, th400 with a gear vendors OD, making 800 on like 15 lbs of boost. killer street car.
Remote mounts are great in rides like that goat where there is no room for a turbo, but in our cars its kinda pointless cause there is plenty of room under the hood. I'd be scared of a pothole taking out a turbo if they were under the car.
