Outer Limits 4x4 Board

Why did nissan stop making the good 4.2td diesel donk , and yet there still puttin the gay gutless 3.0lt in new wagons and utes.

is it just cause of the emmision laws ar is there more to it?

pretty much came down to stricter emission laws.

Emissions yes, but also the introduction of the 3 litre which was way more economical and powerful than the 2.8 put the patrol wagon up there as a good cheap to run and buy 8 seater. Since the 3 litre performance is much the same as a 4.2 (towing excluded) there wasn't much incentive for the average soccor mum to buy the bigger and more expensive engine.

They still sell them at the dealership on this side of the world (Caribbean and South America) though.

Because Massey Ferguson called and wanted their tractor engine back

Just kidding...

dont know why they flogged the 3ltr cheaper. td42 as crate are half the price and u dont need the electronic crap that goes with it...

Isn't that one a bummer...if Nissan read half the threads on TD42's they'd reinvent the wheel to continue the td42!

No need for the just kidding comment. Its true. The reason it is gone is it is an outdated POS. That only just passed emissions when they put the intercooler on.

As for the engine itself. If I could find an affordable GU with a 4.2 I would be happy.

Probably much the same as why they had to get rid of the old holden 5 litre v8.
they researched making a 3 valve head for it and all other stuff to get it thru emission controls but it just wasn't a viable option.
Now look what we've got, an extremely popular, powerful and reliable v8.

Here's hoping nissan give us this with the next "big" diesel they bring out

Was mainly for the reliability and great fuel consumption under load of the mighty 3L and maybe emissions But yes would love a yard full of 4.2td wagons in my shed as a super fund

How true, they just need a reliable diesel donk with some low end power/torque

I thought Mr. Nissan continued/continues to produce the TD42 as a forklift engine?

yeah they probably still do continue to make them.

I've heard they still put "brand new" mitsubishi 4 cyl engines which were first seen in the 80's in forklifts!

I mean i love my TD42 but it's anything but refined.
They'll probably make a great "big" diesel for the next patrol but isn't it gonna be bolted into a softer chassis?

Because a ZD30 with NADS is far better than a 4.2.

Better emmisions, more power, uses less fuel, more drivable, etc.....

And if my Aunt Jackie had NADS she'd be my Uncle Jack. 'Cept she doesn't, just staying.

N.A.D.S?

Normally A Detonated Scrapheap..

Sounds about right for a 3.0L

haha thats about right too

For those that don't have a clue and arn't on patrol4x4.

NADS = Nissan Anti Detonation System.

Boost & EGT gauge.
Dawes valve
Block EGR
Oil catch can

That's more like it.

Nice work, nothing like not buying an engine with the Nissan Accentuated Destruct Sequence built in.

Blocking your EGR throws your emmisions point out the window, And i'm not sure how it's more drivable when there's no one home off boost???

Blocking the EGR has nothing to do with emmisions. It is to stop carbon and other crap getting into the motor. Even with the EGR blocked. It produces less polution than a 4.2.

Have you ever driven a ZD30 thats had the factory boost control bypassed?
Off boost? hahahahaha. I get 6psi @ 1200rpm, 10psi @ 2000rpm & 16psi @ 2500rpm. I will be on boost before the 4.2 revs to 1000rpm.
I could get 6psi @ 800 - 1000rpm but I like my turbo.

Well bugger me if EGR has nothing to with emmisions then I wonder why it was fitted in the first place??? I'm glad your happy with your grenade, but one day it's pin will fall out and it'll go pop like the rest of em. And I'll be laughing all the way home in my outdated, smokey, tractor like TD42.....Nothing anyone can say will change that

I never said that. I said blocking the EGR has nothing to do with emmisions. I am aware that EGR is there to reduce the nitros oxide levels. Blocking the EGR is something we do to protect the motor. It is also usefull on a 4.2.

Here is one for you. How many modified ZD30's have gone bang? Zero is the answer. We have worked out the reasons why and instead of burring our heads on the sand we have done something about it. As a up side. The drivability improves with these mods.
As for how long it will last. Only time will tell.

I'm not trying to be a arse here, it just give me the Sh1t's that people assume the ZD is the "better" engine on the basis that's it's more "modden" and has "technology" Well as a diesel Mech for a large freight company where we are still one of the few who fix things rather than bolt new bits on, do our own rebuild's etc, You don't need to convince me of the benifits of blocking off EGR systems, I see the mess it makes of "modden" truck engines every day. But we have to live with it now, I just see pleasure in working on and driving an engine from a simpler time, when less sh1t went wrong because there was fcuk all to fail in the first place, That's my view of a "better" engine. Your free to your's..cheers

Believe me that I do tend to agree that the 4.2 is a good motor. I just like having more power and better fuel ecconomy. The reliability isssue has been resolved so I don't have to worry about it going bang any time soon. In the end they are both simple diesel engines. There is nothing special about either of them. The only thing technical about the ZD30 is the POS computer that controls it. Take that away and apart from the IP. It is as simple a motor as the 4.2.
My 2c anyway.

On another note. Another stock ZD30 has gone bang. made it to 460,000km before it died. Not too bad hey.

Far out this thread gets better and better...

Mate what are you saying here, that a modded 3lt would have more power than a modded 4.2??? If yes I would really love to see this... of course the little 3l donk will boost up quicker, and thank god they do as they have 1nm of torque until they start producing power. Cant compare the 2 cause there is simply no comparrasin... yes the new 3l are awesome on fuel etc etc but a modded 3l will not produce the same torque /power as a modded 4.2 ...

I've never said that.

How much power either engine makes comes down to how much work is done to it. A stock ZD30 makes more power than a 4.2. so it is already infront. It is very easy to make a lot more power with minor mods on a ZD30. Not so easy on a 4.2. (Turning up the fuel in a 4.2 so you can't see behind you because of the black smoke does not count. )
Sure there are more modified 4.2's out there. This is because they have been out for longer. People have been building ZD30's with 150 - 200hp for a while now and the list is growing. People are even starting to mod the common rail engine with very pleasing results.

He was making 90 rwhp on 35s prior to mods. Now its producing 185hp and still has a new exchaust and more tuning to come.

As for the ZD30 boosting up quicker. Its got nothing to do with the engine. It's the VNT turbo. We actually slow down the spool rate these days with a incab needle valve to add to the longevity.

I'm not opposed to either engine. Hell I even taught my wife to drive in a shorty Mav with a non turbo 4.2. (when it was new. )It was slow but got us most places we wanted to go.
