Default 2.8 Diesel hilux ready for turbo options

Hey gang!
I recently bought a 1994 dual cab Hilux with a brand new 2.8L diesel donk, it was rebuilt top to bottom including, injectors, fuel pump, head and bottom end.
I love it heaps but it struggles up some big long hills and I am thinking of adding a turbo system to the engine.
How long would I need to run the engine in for? I have done 2000km on it so far and the oil and filter was changed at the 1000km mark as reccomended by the engine workshop from where the work was done.
I will change the oil and filter in another 3000km to be safe.
I have heard that by fitting a 2.4L surf turbo, exhaust manifold and hooking up some oil and air lines and having the pump timed or something can yield up to 20% more power and torque which is fantastic!
Where do I start looking for this stuff (what model or year surf do I track down?)
Where do the oil lines hook up? (feed and return?)
Can I drive the hilux to a dyno tuner to have the pump timed?
Does the drive train and cooling system need attention because of the extra grunt?
what kind of exhaust would be suited to the turbo? (2.5" straight from dump into single muffler?)
What kind of cost would i be expecting from start to finish? (rough ballpark figure?)
Lots of question I know but I gotta know

I will be keeping the standard size 31" tyres because I am really liking the correct reading speedo alot so hopefully the power increase will be put down to the ground a tad better eh

i want to do this to my ute as well as far as i know a 2.25 exhuast will do the trick because thats all the surfs run standard but a 2.5 would probably be better the manifolds can bolt staright up although you just change the studs in the side of the block there are holes to fit and yes a dyno/tune up would be needed to get the most of ur new set up a litte more fuel would be needed

The info I gathered today was that for a "air power systems" turbo kit, fitted and tuned by the diesel place here in Bunbury would cost $3600 with all water and oil lines hooked up drive away no more to pay.......except for a 2.5" exhaust system fitted which is about $400 with just a single muffler and mandrel bent system.
The fuel economy would actually improve by 10% and power and torque would increase by 30%, but the clutch "MAY" suffer, fuitting a heavy duty item would fix that though "IF" it did show signs of slippage.
I would be fitting a Pyro meter just so I can keep an eye on the exhaust gas temperature during long hauls up hills on hot days, wouldn't want to push the engine under those circumstances hey.
I did see that DTS sell roughly the exact same kit through 4x4store for about $2600 give or take $50, you need to fit it your self then have it dynoed, probably much cheaper than having a shop fit it too plus you get aluminium duct work with rubber couplings instead of plastic. I guess the aluminium would make the turbo noise more audible mmmmm
more research due tonight

If you are thinking about turboing it perth 4WD centre have a aftermarket DTS system for the 2.8 in one of their wrecks... might be a lot cheaper for you in the long run... just a thought

diahatsu rocky turbo diesel 2.8 l is basically the same as toyota maybe some stuff bolts up, would be cheaper than buying aftermarket parts.

if your handy with your tools you can get a 2.4Lt engine and change the manifolds your self, when I did mine the gaskets and getting some to put the oil return line in ( punching a hole in the sump ) cost around $300 the all you need is a engine which if someone has done a headgasket there the perfect donner

so to do a surf conversion from a 2lte you need:

The turbo
exhaust and intake manifolds
oil and water lines
all the duct work
anything else that I have forgotten?
may have a unit lined up so just gotta get a few details of whats needed
