 Turbo for V6 4Runner (Heaps of Q's)

I have been pretty keen on supercharging (SC14) my 4runner for a while now but after reading "21st Centuary Performance, Julian Edgar", "Turbocharged, Corky Bell" and seeing this V6 already done I have changed my mind to a turbo.
http://www.pirate4x4.com/forum/showthread.php?s=03 6409f6fb9073433eddc23d1ea1289e&threadid=39571& amp;highlight=3.0+v6+turbo
I'm am planning on running just low boost of around 6 psi but I have got a heap of questions on the overall setup. I have talked to the guy above in detail about his setup and I'm hoping to do mine for a little less $$$. He is running extra injectors and a MSD boost retard ignition, which after paying for the AIC and MSD it starts getting expensive. I'm hoping to just do a basic setup with a Rising Rate Fuel Pressure Regulator, extra fuel pump if needed, and hopefully leaving the timing alone.
So my list of questions begins.
1. I have been told the easiest way to size a turbo is to get one of the same capacity motor and cyls. So what comes out that has a good turbo (preferably cheap) with a 3.0L 6cyl.??? And roughly how much?? (VL turbo maybe??)
2. Rising Rate Fuel Pressure Regulator, how much, where from??
3. Will I need a new, or auxilly pump to reach the required fuel pressures under boost? If so what pump, where from, and how much?
4. What is the procedure to get it approved with QLD. Transport? Will emission have to be met and will they approve it??
5. Any other advice at all would be great.
Thanks
Dave

Number one, How are you going to fit a turbo in that engine bay? There ain't even room to move a spanner! The only place that it will fit is on the passager side and it's a long way for the exhaust to travel from the other cylinder bank.... And those pic's on the other forum show exactly what I thought... different and what a heap of mucking around!
Cost, well expensive, considering the amount of fabrication, and being a 3VZ and not the 3VZFE or even a 5VZFE, it would rev too well....
Twisty, for the cost involved, and having just sold my 4 runner, I was looking at a 1JZ or 1UZ engine, close to 200Kw's out of the box and a heap more can be extracted! another option that did come up was a TRD s/c 5VZFE, but was sold before I got a looksy ($5500 complete), and the 3VZ have a well know H/G blow out problem, so modding that was out of the question... in the end someone offered me a good price for my car which I couldn't refuse!

There is a fair bit of room to fit it, it's not as tight as the one on the link, as I don't have the the steering shaft and brake booster on that side. I also have a 3" bodylift so there is an extra 3"'s of clearance under the bonnet as well. It is still going to be a little tight, but fitting is not going to be too much of a problem.
The standard manifold works perfect for a turbo installion. The drivers side of the manifold has a crossover that wraps around the motor to the passenger side and has a head on with that bank. From here it drops down to the rest of the exhuast from the middle of the passanger side bank. If I knew how to post pics on this I could put up a pick of the modified manifold to suit the turbo, there isn't too much in it.
The headgasket issue is a problem, but I think it shoudld handle it. The other guy is up to 12psi with no probs after a year and a bit, and I'm only going to be running half this. Mine has been fixed already by toyota for no cost, so hopefully it will handle it.
As far a complete egine swap, I think it will add up to too many $$$. I'm hoping to pull this installation off for around $1200-$1500, which I hope is possible.
