I saw a thread on an other forum i like to check out. these are some of the pro's and con's that i could tell.

cons:
the theory itself seems sound... but there is a draw back to running this system. i'm sure a lot of us have seen top mount intercoolers. one of the original reasons they did the top mount set ups is to reduce i/c piping. by reducing i/c piping you reduce the actual distance that the air has to travel from the turbine to the engine itself to create better boost response, good for drifting. another thing is that like any turbo set up you will still have to replace injectors and ecu when you want to go big, so saving money really doesn't happen here. also you would have to keep stock ex and or modify the one you have(but you have to buy mani's and pipes for regular turbines also.) intercooler piping would have to be run under or through the car or truck. not good for a lot of us who are slammed, lickin the ground, layin frame (lowered)

pros:
keeping the turbine this far away from the engine bay will allow it to dissapate heat better. there for the turbine will stay cooler and not need so much lubrication and in turn last a little longer(theory). pulling air from that far back and under the car will make the intake air colder as apposed to a regular setup where most of the air is beeing taken from right next to the mani. also it will be a lot easier to work on, remove/replace/rebuild, as well as all the extra space under the hood.

well i kinda like it but will stick to the conventional methods for now seeing as i am flat broke...haha

what do you guys think?

REtarded! I don't really see any pros, but I sure see some cons. Turbos don't only use air flow to turn the turbine. Almost as important is the thermal energy of the exhaust gases. This is why turbos are mounted so close to the head(or rotor housings) and the reason you WANT heat in the turbine housing. There are people who run insulation to KEEP the heat in the turbine housing. Between that and the 500 feet of piping(added weight, loss of heat in exhaust gasses, and reduction in eficiency) make this an all around bad idea. IMHO

Hehehe, I know someone who is about to run a custom setup just like that on a 94 Supra. He's running an F350 deisel turbo (HUGE) with the variable vein turbine wheel being controlled by an AEM. The profile of the veins changes as the turbo builds boost, which gives almost instant boost on the low end and crazy HP up high as well. The only difference is, the one in the illustration looks like it's mounted between the rear wheels, while the Supra is getting it about 6 inches from the exhaust tip, so you'll acutally be able to see the turbine wheel in the exhaust tip. Ok so let's refresh, 3.0L inline six driving a turbo bigger than both my fists with only 6 inches of exhaust on it. OH MY GOD is that going to sound badass!? But you guys are right there are a lot of drawbacks, 12 feet of I/C piping being one, lol. Even with a variable vein turbo that's going to be lag city. But hey, it's a Supra, couldn't have it any other way Not only that, think of how dirty your intake is going to be back there, unless you have some kind of a shield. Other than the badass sound and slightly lower intake temps I don't see much point either. Good to see someone trying something new, though. It is definitely different!

Can anybody say turbo lag?

not really. technically speaking it would not lag any more than a normal turbine accept for the loss in ex temp from traveling that far. but that's just what i think.

it seems interesting, but i was also under the impression that with that much piping, the lag time would greatly increase. i think i'll also stick to my traditional setup for a while .

no you WILL do this cody. i command you! haha
