Should have read this post first.
Interesting your comment about only minute increase in power, makes me think why bother.
Best template I have seen for the plate, thanks.

No worries. Took my plate off and redrew it in Illustrator.
There's a few reason to do it. I guess the ultimate being that it's increases your fuel economy by up to 25% and it's actually cleaner for the environment. Read the link in my post and it tells you about which gasses it cuts back on.
Technically, it doesn't deliver more power, but, if your 4wd is turbo then it makes the turbo spool up quicker which means getting power slightly earlier. So in a way it is more power, but it isn't.... does that make sense? haha.

No it makes perfect sense mate, good thread!
Would be handy if you need it quick as the 2.8's can be slow to pick up rev's.

Uuummmm thats not quite correct in our context... EGR is how Nissan chose to manage Nox emmissions to meet world anti-pollution standards. I totally agree EGR on its own does raise particulate and gas pollutant levels but these are managed by other anti-pollution systems on their engines. Therefore blocking the EGR significantly raises Nox but doesn't correspondingly lower particulates and other gases as they are already being managed by filters and Cats etc.
Don't get me wrong... I am in favour of blocking EGR (or reducing it on CRDs) but purely for selfish reasons ... it doesn't help the environment because with all its drawbacks there is no way Nissan would have EGR there unless it was absolutely necessary to meet the anti-pol regs. If they could get 25% better fuel economy without needing it they would be dancing in the streets.

What's an environment? :P Nah your right with your comment. Probably not the best for the environment. Just like massive oil spills in the ocean and factories pumping out tonnes of gasses through their chimneys.. whatever we do we're adding to everything.
As for fuel economy, not every will see up to 25% gains. Most people probably won't even notice any change.. but it's pretty hard with 4wd's. They aren't the most aerodynamic beasts. Plus, we add all these accessories to our rigs and kind of expect the same economy. Suspension lifts, bullbars, rear bars, spotlights, roof racks, this that and the other.. all adds wind drag and uses more fuel.
Maybe I should change my sales pitch to "Reduces Exhaust Gas Temperatures".

ROFL.. Hiya G Unit
Actually the biggest plus in my opinion would be the big reduction in soot and particulates getting shoved back thru the engine.
From the many discussions on the 'net about EGR the one common thing that stands out from all the posts is how much cleaner everyone reckons the oil is. Considering the oil is only getting a small percentage of the crud as the majority does go out the exhaust eventually it must be a VERY beneficial mod to reduce engine wear.
Waddya reckon Rusty... perhaps we need a Perth Garage Day and knock over all our ZD30's together

Wash your mpouth out ET, mine has six pots not four, go the mighty 2.8.
Garage Day is a good idea though as besides the EGR I have a list of things to do and am a long way from a competent mechanic.

Do the dealers and workshops around do this modification?
And is it something that is commonly done?

I doubt it if a dealer would do this mod but a good off road workshop Should be able to.
Yes its a commonly done mod, in fact there is a spread on it here in the DIY section under: Nissan Patrol Reference Document. it outlines this mod & a hole lot of other info as well.
