extending zd30 life span comment here please

[wattsy2013st]

hi all,new patrol owner here and i want it to last forever of course.i have read that it could be benifitial to your motor to do the following things,an these are the mods im thinking of doing if correct (correct if needed please)
block egr with plate...install catch can...egt probe and gauge....install super carperformances diesel smart module package including 2.75inch exhaust.....dawes valve......scangauge

now from my understanding.....the egr causes build up in ports which causes the maf senssor to give false readings causing over fueling??? idont no, which then causes melting piston......thats my uneducated understanding atm, am i close or is this the case for pre 07 models only

[wattsy2013st]

also can i use the scan gauge as my boost gauge,egt gauge

[threedogs]

More so earlier than 04, Di not so much Cr. Put the pillar pod on with EGT and boost guage of your choice, provent catch can, Then start getting your NADS together, PM MUDSKI on the bits you'll need and pricing. A must read is in archives by Chaz yellowfoot {guru} he has written heaps on this subject some may say the bible, I would, all the diagrams you'll need as well.
Any other questions fire away but do guages first so any mods you'll be able to see any changes.

What are you driving, may help

The Scangauge doesn't do EGT, but it does boost, as well as a heap of other things. Pretty handy bit of kit for the price and is an easy plug and play fit.

The current CRD motors aren't as prone to the problems of the earlier DI motors and generally don't need the full NADs fitup done. That's not to say they wouldn't benefit from it but it's not absolutely necessary like it is in the older motors.

The other thing to be mindful of, especially with a brand spanking new car, is your warranty. Fitting things like a chip or an EGR blank could cause you hassles with warranty if Nissan notice they are in there. Chips, like the DPChip, these days are pretty much plug and play and can be removed pretty quickly prior to giving the car to Nissan for a service, the EGR blank can't be.

The oil catch can is a good thing, and something I'll be getting on mine when funds allow. A decent exhaust is also a great thing and from all reports the 2.75" is the go for the CRD engines.

Gauges and pods are many and varied, Autometer are pretty decent gauges and the pillar pods look great.

The guys here have a wealth of information to share, they're the only reason I now know the little I do :)

[wattsy2013st]

ok so this is where im at,ebay was a big help,twin pillar pod, procomp ultralite boost and pyro/probe,provent catch can,egr blank total of $720.........dawes and needle valve??????not quite sure wich controler i need or if the needle is seperate or if included if not which one of those to, any ideas on part numbers or exact names of each

[wattsy2013st]

What are you driving, may help

we have just brought a 2013 plated st wagon in silver tint and colour coded bull bar

[happygu]

You don't need a dawes and needle valve for the CRD.

It doesn't seem to overboost like the earlier Di's. If you have a Boost gauge anyway, you can keep an eye on it.

EGT's are the main thing to monitor, and that seems to be the case with all high tech diesels.

[kevin07]

after you fit gauges get a plug and play bogard turbo timer as you will not like shutting your motor off with the high egts that you will become aware of. you wont need the dawes. kev

[boots]

Have read here that CRD engine with EGR block do tend to throw fault codes and scanguage is required to clear fault codes . Someone with a CRD will confirm or deny this .

[threedogs]

I'll X2 you Boots have heard they throw faults as well only minor problem though,
it will run higher EGTs than the Di Z30s

[threedogs]

Also be aware that any mods would need to be removed for servicing etc, if not get it in writing from Mr Nissan that such and such is ok. Don't just take their word for it

[mudski]

How much have you been quoted fir the dieselsmart module and zorst?



I tapped that app...

have read with bigger exhaust she might over boost is this correct?????

looked on supercarperformance.com there module is 1290 and they also have a egt kit with sounding alarm,if still gets to hot after alarm the egt kit will turn of the model and car will return to standed........they also sell exhaust for round 1100 or so but iv seen cheaper else where have to call them monday to confirm prices

threedogs there module plugs into injectors im prety sure,,,there website claims to only take a few minutes to install so hopefully its that easy

[wattsy2013st]

lonicus you have a 2012 trol will you bother with the nads setup or leave as is,are these crd motors safe from the di problems and im being over concerned

[Lonicus]

I'll only be doing a part of the NADS setup, mainly because the CRD don't really need to go the whole way and I don't want to give Nissan any wiggle room on warranty should I ever need it.

I won't be doing the EGR plate or Dawes valve. The plate I may put in after warranty but it's not a priority for the CRD, therefore I don't need the Dawes. There's no over boost with the 2.75" exhaust and from what I've read from the guys here, and other sources, the 2.75" suit the CRD engines pretty well.

I'll be putting in an oil catch can, only good things can come from that.

I don't know if you plan to do the fitting of this stuff yourself, but as the guys here have advised on many occasions, at least put your boost gauge in while the car is still stock so you can see how it runs in factory setup. That way you'll be able to see what effect the mods have on your engine. If you're not doing the mods yourself think about getting a Scangauge and plugging it in prior to starting your mods. It takes about 2 seconds to fit and you can monitor your boost, and if you do fit an EGR you will need it to clear any codes that pop up.

As with most things, you get what you pay for so don't necessarily go for the cheaper options. With the exhaust for example it might only be a couple of hundred dollars difference between the best you can get and something not quite as good. You're keen to protect your car and get it running as well as it can so get the best bits for it, even if you have to wait a little longer to get them.

Cheers

Fuel return line mod is worth considering to prolong fuel pump life . check out this thread above .

good advise,,, iwas starting to wonder if a full nads setup was needed,will start with boost gauge,egt probe and gauge,and provent catch can,..........

[Ben-e-boy]

The biggest thing that no one has mentioned is servicing. One of the blokes at work has a grenade model 3L with close to 400,000 on the clock, completely untouched, the motor is as clean as a whistle as he has an intensive service shedule which he meets.

[threedogs]

Ben e boy some Z30 may only travel a short distance to work everyday and never warm up properly,
others may travel 100k each way to work. seems there is no one common thing linking the grenades
except year of make. servicing must play a huge part,oil type,filter used etc. looks like all these things
need to be spot on. IMO luck is the single biggest factor. I have heaps of thoughts on this issue.
Good on him for such a trouble free run. If yours is a daily driver look at condition over all to someone
who has company car, and parks the Patrol for sometimes weeks one end,

Save the money on a boost gauge and put it towards a Scangauge or equivalent. Absolutely brilliant bit of kit and will display what the ECU is seeing as boost, water temp, fuel flows, volts, engine load, etc etc also reads any fault codes and some handy trip computer functions like fuel used/remaining etc. Can also be calibrated for accurate speed if you don't have a GPS onboard

[Squalo]

As far as I can tell, you really don't need to do a thing to the CRD when purchased new except perhaps extend the warranty if you plan to own it 5+ years.

EGR block is not a bad idea, ditto for a catch can, but if you aren't modding for power and don't work it hard then IMO there's no real need for boost or EGR gauges.

Certainly no need for Dawes or needle valve unless you have an early CRD which doesn't seem to have as good an ECU as the 2008 re-mapped one.
