    I am very appreciative of the input that so many have given on this matter.
    I do have a couple of extra questions now based on what others have said.
    1. Can I get an upgraded intercooler without getting a new turbo?
    2. Is this a half step?
    3. I understand (now) that added induction without turbo changes is maybe not worth the effort.
    4. That I don't need any of this, really.
    5. If I was to bite the bullet and try to get reliable, increased performance as a tow vehicle (I am not a rock crawler, I am a tourer) what is the optimal setup?

    I like my 3.0 GU3 Di Patrol. It has been an excellent servant.
    As I lay there looking up, taking in the spectacular view that was the night sky and the multitude of stars I asked myself, where did my tent go?

    1. Yes, indeed highly recommended if you chip it
    2. No
    3. Agree with factory turbo, after all they are a VNT so they will keep boosting till they max out of vane angle or run out of air
    4. I would, chip, 'cooler, nads, egr block, are all pretty much bolt on and 3 inch exhaust with EGT bung is for some but I get a shop to do it (dunno what you have already and too lazy to check back :-)
    5. That was how mine was set up, Tourer, but I did VNT adjust instead of Nads 'cause mine was a CRD

    I have been ringing around to see who can do what in terms of ECU remapping or Chipping and have been told you can't remap the Di.
    The suggestion is getting a chip and playing with the settings myself or paying for a Steinbauer and having it installed and Dyno'd to the correct settings.
    They would also remove the Dawes and set up the VNT boost control.
    $2400 total.
    I think I will get the upgraded intercooler and see if that is enough. It isn't pitiful at the moment, I just wanted less temp and more speed on the big hills. It may just not be worth the $ for hp conversion.

    ECPT do remap for ZD30DI (refer post #6):

    http://www.nissanpatrol.com.au/forum...l=1#post780466

    Post ECU remap_ I am currently trialing the control of max boost with Tillix in conjunction with the stock VNT vac solenoid and achieving a very good result(linear spool, lower EGTs and slight improvement in ECO). Others achieving similar results. Very impressed and is an improvement over full manual boost control (Tillix/Dawes and needle valve).

    IMO do your mods progressively and observe and record the performance changes along the way.

    Yes/agree, upgrade you IC first. What are you thinking of and at what price range?

    Forefront, HPD and then Cross Country in order of expense
    Researching the Forefront at the moment.
    Debating the need for the fan v's cost increase.
    Ebay jobs are much cheaper but maybe for a reason.

    Guess U are considering direct replacement in size, the CC Upgrade with fan, a few $s (Tube & Fin core), good piece of work and be also suited for follow on upgrades if U end up doing more.

    The Forefront is 23% larger than stock but doesn't have a fan.
    It's about 1/3 of the price of the others as well.

    I went with Forefront and got a fan separately, easy install and the fan does make a difference. I have a separate switch for the fan and turn on when required.

    Understand that Forefront are a bit thicker, Chinese cores, welded instead of crimp(stock cooler) and the size I made reference to was footprint so "direct bolt on".

    Do not think you will see significant reductions in EGTs but an improvement over stock cooler.

    Impact on EGTs from using different cooler used on my CRD for your info. Test conditions : ECU remap, 4th gear CRD test hill 75% eng load and actual boost on haul 15-20psi:

    Stock Unknown(no gauge)

    Adrad IC (Aust/NZ made(Chinese core - near stock size core / Bar &Plate) - 575DegC

    Jonny Tig (JT) Cooler - Similar to CC Ultimate (600x300x76mm core / Tube & Fin) - 450-475 DegC

    JT cooler with improved induction (post #18) - 425 DegC (with my current set up, climbs it easy now)

    Note: Based on anecdotal evidence, CC Upgrade can provide 100Dec C drop in EGTs (presume hauling)
