Ok I know this has been talked about alot but i have a few specific questions.
Firstly, how do you go about adjusting your fuel pump once the turbo is on?
Are there many options of upgrading fuel pumps?
Would like to hear from any one who has put an intercooler on one.
I have a PTO so limits options for piping but was thinking if you relocated the batteries you would have a lot more room to play with.
Good idea or bad?
read an old post on air to air vs water to air coolers.
was thinking water to air would be the option to go for as a lot more efficient at low speeds, also you can get them pretty easy off 89-93 leagacy's.
Other option is to set up air-to-air with waterspray unit to reduce temps at low airflow.
Any thoughts?

my next mod is going to be intercooler, prob air to air under bonnet version with a fan to push hot air from the engine down. im also going to change my snorkel from a air flow unit to a 3" or 4" stainlees tube, get as much air in the old thing as i can, if you are thinking of turboing, dooo it ! it really makes the truck.
Fuel can be increased with a clockwise turn of the main fuel screw. About 1/8th – ¼ turn is all you should need. Ideally, its best left to the experts as if not done correctly can be detrimental to your engine.
The std Nissan fuel pumps can’t deliver enough fuel to match a decent turbo setup, even with the fuel screw wound right in, so pump upgrades like what we do really are the only way to go.
Best suited to a capable club truck or race truck, the upgraded pump increases fuel delivery by almost 100%. This is a conservative upgrade but still produces decent HP. Roger McKay runs one of our pumps in his GU ute. When he took it to Outback Challenge in Aussie this year, it had plenty enough power in the sand and the engine never got hot. We run a more modified pump in our GQ race truck.
Any upgrade to the fuel system requires improvements to the air intake to make best use of the increased fuel. Prefer 4â€

Thanks guys. I am definitely considering... Have turboed quite a few vehicles... but so far all petrols.
Cheers for the info.
What filters do you goes run?
Do you use hi-flow motorsport ones? pod style?
mudchuka was thinking bout your idea... read it in another post.
Only problem with top mount coolers is the heat, even though you would have a fan you would still get radiant heat from engine. A heat shield underneath the 'cooler would help.
Just had a look at my engine bay, you could a smallish 'cooler above your diesel pump sorta, takin advantage of the room left by your removed air filter box. You'd be on the opposite side from the 'zaust then and not above a hot engine.
i would think about a decent bonnet scoop and vented underbody guards to keep the air moving
