This has been adddressed;

No it won't.
I take it you have not looked at any dynos of rear mounted turbos.
LS1's & LT1's are spooling up full T4s by 2500rpm using 2.5 or 3" piping.
The air is already flowing through the piping. It's not like the turbo (or turbos) has to pressurize completely empty piping. 
There is less pressure drop (i.e. causes "lag") over 10-15' of piping then across ANY intercooler. 
I suggest you check out some information on a properly mounted rear turbo. It performs nothing like I imagined it could. There is zero lag & more temp drop then a decent intercooler.

I think a turbo in the engine bay is way more functional than one at the end of the car. I'll go ahead and more reasons against it, too low to the ground, turbo and air filter get too dirty. Really, just keep it in the engine bay, it'll be mo betta.

Lots of stuff works. I've seen dynos of people hooking up leaf blowers to their intake and actually gaining hp but I'm not gonna do it.
Ultimately, you can't compare gains on a 5L+ V8 to a 2.0L I4, totally different setups. Also I would not do any setup that required a separate oil pump to pump the oil back into the engine. If it ain't gravity drained I'm not interested.

so what you are saying is you wouldnt install a proven power adder to your car because it doesnt look like everyone elses?.... time to think outside the box....358hp 4cyl...

Lag has to do with turbine sizing compared to the engine...
on a rear mount turbo set-up... you just have to size it differently than you would on a conventional set-up. Then you don't have as big of Lag problem as would be expected.
However I would imagine the rear mount is not as efficient as it "could" be...the losing of heat mostly...but it does work.
Easier to install and uninstall...they get pretty good gains.

Just what the world needs, another honda turbo kit. 
Oh, and I wouldn't hold up a magazine called Hot Compact & Imports as your holy grail of tech. I only skimmed the article but does he have a FMIC? Wasn't the setup supposed to not need that? Way to think outside the box.
And you see the sig? I've been turbo'd for well over 3 years now. I got turbo'd when there was nothing for our Zetecs. Oh wait, there still is nothing for our zetecs. My kit was built from scratch using whatever I could find. Some metal from a plumbing supply house, some exhaust pipe, a turbo from ebay, etc... My dad built a kit for his Focus using the techniques learned from my setup, also from scratch.
The only other person here I'd look up to as an example is Loco cause he also took the FI plunge into the unknown. Granted he went supercharged, and I'd never go SC(but that's a whole nother argument). But I'd sooner go supercharged than install a remote turbo setup.

i posted that as to show the 4cyl remote mounted turbo...a previous post you said you cant compare a remote mounted v8 turbo to something used on the zetecs....it may not be a technical marvel for a magazine but the magazine didnt install the guys turbo....im happy for you that you built your own turbo....that wasnt anything i was speaking out against....but its not like you built the first turbo ever...so although its cool that you did it...youre not that big of a pioneer....just my opinion of course...

If it makes you feel better.....IF I had a MTX, I would have gone turbo instead of superchager.
