Outer Limits 4x4 Board

Hey All,

What are the pro's and con's of chipping the GU 3L TD.

Most things I hear are all good, but here must be a downside. I spoke to stand at a camping show and they said I must fit a 3" exhaust with teh chip as the heats will start to kill things. Was this truth or a selling pitch for another $1000 exhuast ?

I hazard a guess, manure, theres stock Gu's in our club with chips...

but with the grenade, would you risk overheating it?

Thanks,

The guys in teh club do they have larger exhausts or not, how long they been chipped for, any problems ?

Mate i would say don't push your luck by chipping it ,quite a lot of the blown motors seen have had chips.

Ta, I heard the 3L runs quite high boost. Most manufacturers make a engine to a cost and to handle the stock amount of power. Why push your luck or shorten it's life span.

There are 200+ members, there are grenades of all forms of tune ( but happily there are more 4.2s )from stock, to stock with big tires, and chip, to $9000 spent on one grenade inc rockhoppers (he would be scared if he knew how capable his stock car was ).

Have had a few blowups in our club, and I know for fact 3 were chipped, and others not....

but you couldnt really say it was the chip that did it more than the usual.

I fitted a D Tronic chip to my work Patrol (ZD30) when it was new in 2003. I never changed the exhaust and it has just ticked over 420,000 kms untouched.

there been quite a bit of discussion on ZD30 motor problems over at http://www.patrol4x4.com/forum/ .

i wouldn't be inclinded to get any more power out of it till you made sure you didn't have any of the problems that some seem to get.

actually i'm wondering if some of the chips would actually help with some of the patrols werid motor issues. in particule the dropping of boost (and huge increase in EGT's) at highway speeds.

it can also void your warranty

People bag the 3litre but it was only the early ones that shit themselves. Nissan then made a revised dip stick that put in an extra couple of hundred mills of oil and that apprently fixed it. If yours is an early one i wouldnt touch it with a chip but one of the later ones with more reliability i would consider it.

yes that is another mythical rumour some techs say it was the oil squirter that clogged and made boost go too high and some say they lean out to much on one cylinder and holed pistons ....many other reasons and remedies they gave but mostly BS it was boost related and only time will tell with the new one.

I have also done my research and the general consensus is only Series 1 and 2 models are affected. Mine is a Series 3 (2003 model) and is ok.

Yes the ZD30 copped a bad wrap early one and it has hurt the reputation. Some people will never get over that so piss off. However all engines will have a issue all two and this shouldn’t be forgotten on the ZD30.

In short I don't believe my engine is a hand grenade, but like ALL engines the more HP you push out of them the higher risk of something blowing up.

So from what people have posted looks like no negative outcomes from the Dtronic or other chips.

i know very well (i was there) and know the guy very well ,nissan replaced his 2001 motor with a 2006 3.0 and it lasted 1095 km before it blew ,mate i hope for your sake they fixed the problem time will tell. BTW piss off yourself ...

Dirty GQ,

Mate not tryoing to upset but many people who dont drive a ZD30 still sit there bagging them out.

My mate just bought a new 2006 Subaru Outback and at 10k it the engine blew up. We need to remember all cars blow engines, the fact that the ZD30 had a rough start is hard to shake.

To blow at 1095 I'd say they F%$ked something when instaling it !

Steve

mates forester kept doing gearboxes ,so much they offered him his money back.All cars have issues just go on the info i have seen with my own two eyes,and that is not the only one i know of . I hope they are all fixed for nissans reputation because as soon as you mention nissan you hear arrrghhh! a secondhand 3.0 litre is so much cheaper than the 4.2 i would buy one if i knew it would hold together.BTW the guy that had his motor blow at 1095 k's had a DTRONIC fitted

Did Nissan fix the 2nd engine and determine a cause ? of the Kaboom

patrols ZD30's blowing up as far a i know it ......

the series 1 and 2 had oil problems. partly poor design of the oilways which is why nissian supply a new block with the rebuild kit. 2ndly (at a guess) the early lower grade oil which dosn't like high amounts of soot which high EGR motors make. hence the new CI-4 spec came out (2004 ?? edit: came out in 2001 but spec upgraded in 2004). early ones where having problems with oil gallerys blocking up including piston spray bars.
nissian shortened the dipstick to add about 3 litres which could lead to oil overfilling problems if your not carefull.

the overboosting seems to be mostly caused by MAF sensor failure and i suspect EGR getting stuck (not uncomman in any vechile). both of these can cause the variable turbo to overboost causeing turbo and or piston failure.

also there seems to be a werid thing with the boost dropping at cruise on some vechiles. boost drops, fueling goes up, no change in vechile power output but EGT's go through the roof. this may explain why some are failing because of piston cracking rather than piston melting. no idea why some do it and others don't.

yes they replaced it but were baffled by the KABOOOM and the first motor was out of warranty....way out of warranty but they still fixed it (edit) .

But I agree with this comment. Different issue

Different to the original Series II issue - in those cases the WHOLE motor blew! This is a turbo blowing and I would say, at this stage, that it is an isolated issue.

I don't recall seeing anyone else with a Series IV having major motor/turbo issues. Anyone else?

I think like most people we purchased these 3L engines not knowing the potential problems . Either way the engine performs very well and I'm happy with it .

Should the worse case eventually happen I will deal with it then. However it does sound related to Series 1 & 2. I'm not about to sell and change cars to wait and see.

Have thought about options like that, didn't know what engine though ?

But
Max. output 312.3 PS (308.0 bhp) (229.7 kW)
@3750 rpm
Max. torque 750.0 Nm (553 lbft) (76.5 kgm)
@2000 rpm
Hmm sounds nice
