Hi guys was just wondering what engine mods should I do to my 3.0 CRD ute to make it more reliable and get longer use from the motor and if possible some links or websites where I can find the products so I know the ones I find are of good quality. Would be of great help thanks. ;)
Chris
Hey mate, theres not a great deal to make it more reliable. There a good engine stock. If you want to make it breath better you could put a bigger dump pipe and exhaust, but you will than have to put a dawes valve or similar to stop over boosting. Put a couple of guages in to let you know what the engine is doing. Keep good oil in her and change oil and filters regularly.
Yeah I have been looking at a 2 3/4 or 3" exhaust and service it every 5k will have to have a look a some gauges to fit then. Thanks for the advice
Pillar pod with EGT and BOOST , Zorst, catch can and block EGR, possibly chip it down the road
Definitely need a pillar pod. Catch can and might put in a chip later on after exhaust. Zorst?
Getting the hang of it, gauges are the first thing you need to do, then you'll be able to see what happens with other mods.
highly recommend
Zorst = exhaustQuote:

For gauges, highly recommend ultra gauge, best $69 ever spent
Ohhhhh rito yeah I was thinking it might have been an exhaust I've been looking at a taipan exhaust with steinbauer chip for down the track. And I'll have to have a look at ultra gauge for sure and if they that price sounds good to me. Cheers
I would be carefull about blanking the egr on a crd. theres more to it than just a blanking plate. These engines have sensors to detect the egr so you have to have a hole in the plate to keep sensor happy. To me it defeats the hole purpose. On my previous Di engine yes I did blank
Yeah rito then that does seem to defeat the purpose abit... Will look at a catch can for sure tho.
I have a 2011 wagon myself . No mods yet ( except b/bar & towbar ) but when funds allow I'll be doing the catch can first and then hopefully autron egt/boost gauge in a pillar pod to keep an eye on the motor . Not sure about the egr block at this stage , will look into more.
Nah... no hole in mine... just run a scan gauge or similar. One of the best and cheapest gadgets for a CRDQuote:

The Ferret makes a top blanking plate at the right price just PM him to sort out getting one.
The scan gauge will let you adjust the VNT (if required) as it monitors boost and will also clear the odd P0401 fault code that the ECU throws
I just ordered the ultra gauge does anyone know if this will do the same thing? And will hopefully fit a catch can soon then will look more into blocking the egr because just not sure if this will cause over boosting and will require a Dawes valve
I have 2011 CRD. I did the mods in the following order
1) Scanguage (fitted it in the car yard)
2) Autron gauges & pillar pod
3) Catch can
I have the blanking plate from Ferret but haven't fitted it yet.
Exhaust & chip will be down the road when the finances recover a bit.
Other mods completed which have pushed back engine mods: suspension lift, dual batteries, winch, on board air compressor, drawers, fridge on drop slide...
It's like unravelling a ball of wool - a big beautiful & bloody expensive ball of wool. Once you start the mods, there is no end! Enjoy
If you plan to keep it for a while, a mod I can thoroughly recommend is to get the Nissan (not dealer) extended warranty, extra three years or 150,000km, whichever comes first. $1300 or so. I'm one year into the extended warranty and it has pretty much already paid for itself - serpentine belt tensioner replaced, cracked EGR pipe replaced, swivel hub seal replaced, and about to have the timing cover oil weep (common CRD issue) sorted out, which is an engine-out job.
As for more grunt - exhaust system, then chip, then perhaps an aftermarket intercooler. EGR shim and catch can are a good idea.
With getting the Nissan warranty tho if you do the usual mods like lift kit, tyres, chip, exhaust, egr blocking etc does that effect the warranty tho like Nissan blaming the after market parts? Like what mods can you do before Nissan blame you for the problem or do the mods not really matter?
Squalo ,thats a lot of stuff going wrong on a new 4x4 isn't it?
Patrol94, the EGR block and fitment of a chip are the only possible issues from what I've seen and read. I don't think dealerships have issues with exhaust systems or relatively legal lifts, the two dealerships I have used don't even blink at it, even when it is covered in scratches and looks like hell :)
To deny a warranty claim Nissan would have to have good grounds to say or prove that a modification was to blame.
I remove my chip (wiring harness, black box, the whole thing) and EGR shim prior to each service. The Steinbaeur is easy, the EGR block a bit fiddly. But I don't want them to get some weird code and go digging for a problem that isn't there... but having said that, plenty of guys leave their chips etc. in for servicing and say that the service guys are perfectly fine with it. But then they haven't had a powertrain warranty failure... and if I were a service foreman I'd note the presence of a chip on the dealers records, and why say anything to the customer? The dealer wants their business... and can then reject a warranty claim if something does go wrong.
Threedogs, yes it sort of is a lot - but all are common issues - belt tensioners especially. And although mine is only up to 75,000km, it gets a good workout - neither Mrs Squalo nor I drive like Grandma Duck, and we use it for serious offroad playing, as per my avatar.
Yeah rito thanks for the advice Squalo i am looking at and exhaust but not sure about a chip if I do block the egr I'll just remove before servicing. I just ordered a 2" lift a few weeks ago haven't installed yet but Nissan here did say it won't affect the warrenty but didn't ask about chip or exhaust but awhile before the budget allows for them to again :(
The exhaust is the best thing you can improve on a CRD. A chip with stock exhaust is a waste of money, with a bigger exhaust the chip really get the engine working nicely.
However, you might get a similar improvement with exhaust and a Cross Country (or other good brand) heavy duty intercooler, and Nissan would probably be happy to see an aftermarket intercooler there because they won't have a warranty claim to deal with when the standard intercooler tanks crack...
I have looked at getting the tiapan exhaust, intercooler and steinbauer chip fitted but that is a fair bit of money in the 3 so will probably just get a beaudesert or scotts rods exhaust then chip later on and yeah have heard some average things on Nissan intercoolers
Just get it, you won't regret itQuote:

Nissan do not want to know you if the repair under warranty is going to cost them. And our Patrol isn't modified in any way. Check out the "Overheating 2010 GU Patrol" thread in this forum. Be very, VERY wary of a wounded Patrol, especially if Nissan Australia think they can blame a prospective warranty claim on a modification done by a non-Nissan dealer.Quote:

First up though I'd still be doing the pillar pod and guages, Mans gotta know whats happening under the bonnet.
Write down all you can think of before you do any mods, like fuel consumption etc.
Will be interesting to see any difference once you stop driving it with your foot in it, we all do it after chip and zorst.
Yeah would like both in time am still wary with the warrenty and need to save abit more as well, just paid for my 2" lift yesty and still new tires next week or so. Ordered the ultra gauge gotta go pick it up at post office soon then will see my average fuel and and what not before fitting lift next Tuesday arvo after work so got a few things before chip and exhaust.. With the ultra gauge would you still get the pillar pod?
Block the EGR, and fit a catch can, before modding the engine for more power.
EGR is the undoing of any engine, have a look at "flash gordons "pics and make your own mind up.

Cheers, the ferret
Yeah i deffinitely gonna have to look at some catch cans and see what one just looked at the cross country anti grenade kit just waiting to find out and see if it fits for the CRD not just the zd30
Hi there. Speaking of EGT gauges, what is a good brand and were is the best place to mount the senor?
Sorry typo.

I don't believe you should fit a dawes valve to a crd. Can someone clarify this ?
Cheers Jock
You can safely fit a Dawes to a CRD to take boost control away from the ECU. The 2007 CRD ECU (first of the CRDs) can occasionally struggle to control boost if you add an exhaust, lots of them getting around with Dawes valves. In 2008 the ECU was revised and it seems to handle boost control better for some reason.
