Hey Peoples... I am thinking about putting a turbo in my v8 soar.. So i was just wondering what you guys think?! Also any help on what to look for etc. would be greatly appreciated.

That setup is seriously flawed. A turbo should be as close as possible to the exhaust manifold so as not to lose energy (heat). If you want to look at some properly engineered setups, you're better off looking in our own backyard.
They won't be able to help you with anything for the Soarer, but check out Air Power Systems for some well engineered kits. http://www.airpowersystems.com.au

I wont get in to a debate about what is better/worse, however you will find rear-mounts a lot more common (especially in the drag scene) due to engine bay size restrictions; ie lack of.

If you are not looking for SERIOUSLY BIG power then rear mount is an excellent solution for the 1UZ as no exhaust manifolds need to be changed. Your only issue will be with lubrication both to and from the turbos.
The diff area has tons of room for 2 x small snails.
The compressed air can even be pumped by plastic piping to the intake. This aids the coooling effect.
There are many fine examples of this on road going vehicles, daily drivers.
It would have to be the most cost effective way to get the most bang for the least amount of bucks.
Of course, you will need an engine management system as the factory ECU would step in and kill off any gains.
$5000 should do it without an intercooler providing you can source everything and do it yourself.

In the Monaro article, I have to admit all that hardware hanging down is dumb, no need for that in a Soarer, there is tons of room to tuck it all up out of the way.

I have seen a good setup on your tube where the turbos fold around to in the front of the engine!!! One thing i must say is you must have really deep pockets and think serious before you take on the commitment because there are some many hidden costs envolved!!! I would more allow for $20,000

Making big power and having a response engine can be, and often are two completely different things. - I know I rather have the latter. - Torque as low as possible in the rev range and an engine that's responsive to throttle input to be more specific.
I've haven't read a lot about the rear mounted turbo setups, to be honest, because I think they'd be horrible to drive on a street car, not too mention all the potential dramas. - oil feed & return, coolant feed & return, potential damage to piping & components due to the location etc. The biggest point, I can't believe anyone's hasn't brought up, is something too many people harp on about in regards to front mount intercooler systems......excessively long pipework. Introducing such a great length of extra pipework on both the exhaust and compressor circuits has got have a negative impact on engine repsonse.
I much prefer turbos to superchargers, but if V8's are your thing and you want forced induction, i recon you'd be far better off with a blower, if you're on a budget. - even a centrifugal blower. cringe......no offence to anyone who has one....

Rainer, rear mount systems are quite popular on some big cube cars. They already have the torque down low so lag is not as much of a problem. Obviously quite good for drag racing too where you can keep it up in the power band. I believe in regards to piping etc it is just as simple as an underbonnet job. While it is longer it can be a lot simpler with more room. So while rear mount (I still smile when I type that) would make no sense on a 1JZ for instance, on a V8 it could be a bit better, and if you have no room, well you do what you have to
