I'm thinking of parting out my 1991 Nissan Patrol (front right side accident).

Any interest in a complete TD42 NA engine, turnkey w/ all accessories ?

under 90,000 miles and strong compression. It's basically a tractor/workhorse engine that is the mechanical version/injection pump so no electronics, similar to the 1HZ.:wrench:

Shipping on a pallet in the US in no problem as I live a few mins from the WA border.

I have no idea what it's worth. It's mated currently to the stock Patrol transmission which is identical to the Infinity Q45/Nissan 300ZX trans but I'll keep the trans.

If there is any interest, I'll post it in the sales section.

You sure about that? In Australia the only patrols fitted with the 300ZX style gearboxes are the wimpy little 3.0L petrol and 2.8L diesel patrols, all the 4.2's have the big box in them.

I am very sure about that. It is a RE4R03A. Please feel free to Google it yourself. The tanny is designed to handle big torque and HP. Have a closer look at what those petro engines put out and you will see.

By the way, the wimpy little 3L puts out more power and torque than the TD4.2. It just doesn't have the longevity. This engine takes very well to turboing. Later TD4.2s (commonly known as the "Black Top" engines) got the smaller connecting rods as Nissan new that the 89-93 TD4.2s (commonly known as the "Silver Top" engines) were over engineered.
 
Aahh your talking about the automatic transmissions, not many of them around in OZ. I am talking about the manuals, the little engined GQ's got the small 300ZX boxes in them. BTW the OZ spec 3.0L petrol's (RB30) do not put out more torque then a TD42, more power, less torque and waaayy worse drive ability with more fuel consumption, though they are a hoot at high rpm when turbo'ed.
 
http://en.wikipedia.org/wiki/Nissan_Patrol ZD30DDTi (Found on Y61s)
Turbo Intercooler 170 hp (130 kW) @ 3600 rpm, 37.0 kg·m (363 N·m; 268 ft·lbf) @ 1800 rpm

TD4.2 (Found on Y60s) This is the OP's engine that he is considering to sell.
125 PS (91.9 kW; 123.3 bhp) @ 4000 RPM
27.8 kg·m (273 N·m; 201 lb·ft) @ 2000 RPM

BTW, I have never had either of my TD4.2s anywhere near 4000 rpm. I am usually in the 1800-2400 rpm range with maybe 2600-2800 on long steep climbs.

Edit: Safari Turbos claim to increase the torque and HP on a Y60's TD4.2 by 41%. http://www.safarisnorkel.com/turbo/td42_gq/sttd42-u.htm Add their intercooler and they claim another 15% increase from the torque and power delivered by the turbo. That's some good zoom zoom. :D

Those zd30 motors are absolute time bomb motors.
Good figures for the zd30 on paper compared to the 4.2t but not in real life.then again the 4.2turbo patrols do going alright but there super good at over heating when they get a work into them,Unlike the cruiser turbo diesels
 
Love my wifes td42. I can hear Her coming well before she actually gets home. I always look like I'm doing something useful when She pulls in to the house. Highly recommend this motor for someones wife's car.

Joking aside the entire drive train from this truck is bullet proof 100% and would be awesome for someone doing a diesel conversion. Good solid low tech at its peak.

:lol: I usually know when my wife is about a block away in her Safari. I can't hear it but my dogs can.

I have a ZD30 ecu coming which I intend to run my work car off. When I get into the maps I'll see if I can find out how they overfuel. The YD25 and YD22 run the same ECU type and don't have the same issue.

Thats the 1st Ive heard of the problem outside oz,but it doesnt surprise me. There is some stickies on one the aussie patrol forums where they have a list of things to do to minimise the chance of the engine exploding.
One of the things is to keep the MAF sensor clean so it knows when the engine is breathing hard.

Its a big headache for Nissan,obviously they cant continue with this engine but they dont want lose ground to Toyota by not having a diesel option.
 
There are two versions of the ZD30 used in Patrols:
ZD30DDTi Turbo Intercooler 158 hp (118 kW) @ 3600 rpm, ZD30DDTi Turbo Intercooler 170 hp (130 kW) @ 3600 rpm, 37.0 kg·m (363 N·m; 268 ft·lbf) @ 1800 rpm. IIRC, it is the 118KW version which was the earliest and had the most problems. Because it had so much blow-by, the only way to keep the MAF clean was to install a oil catch can. So like the BEB in the IHDT, this was the first thing most owners did to extend the life of the engine. Checking that the MAF was clean has become a part of regular service. Reports of grenading have gone done a lot in the last few years.

There's a lot of misinformation in here.
There are many different ZD30 types. They start with non turbo and work their way up.
The non turbo is a rare beast and hasn't got the power to melt itself.
The version used in the Navara (wastegated turbo, non intercooled, VP44 pump) appears to have the least trouble.
The version used in the Terrano/Pathfinder/Patrol with the VP44 has the most trouble. This one has the VP44 injection pump, VNT turbo and intercooler. It has around 110kw.
The current engine is commonrail. Completely different injection system, I don't think it has the problem.

Blowby enters the intake after the maf on all nissan engines. Blowby is not the cause of fouled MAF's. Nor is a fouled MAF responsible for an engine deciding to overfuel. My nissans use exactly the same maf sensor, when they get fouled the output voltage drops and so does the engine performance. It would take an internal short to give a false high MAF reading. But regardless, a false high maf reading should not be able to overfuel an engine. The torque limiter in the ECU is supposed to have final say on limiting the injection quantities.

All of the people selling "anti detonation" kits have no idea. I haven't seen one of these kits with an EGT gauge and an EGT gauge is all that is required to spot an engine overfueling so the driver can reduce the load. In fact the most popular document on ZD30 engine problems claims they lean out and melt. The author thinks it is a petrol engine.

:confused: Dougal, you really need to read posts more carefully before responding. Take a look, I only talked about the Patrol. Moreover, I am only going by what Patrol ZD30DDTi owners have stated over and over on the Patrol forums in your hemisphere. Don't believe me, have a look yourself. Of course no one will ever have your experience or knowledge, so they could definitely be all wrong. :rolleyes:

The joys of sarcasm. Are you aware that the same VP44 ZD30 used in the patrol was used in the Pathfinder/Terranos? Did you know the ZD30DDTi model code is used for both the VP44 and the commonrail engines?

Beleive me, I've looked at all of the information on the net about this. I'm also the only person I know of in NZ or Australia to have remapped one of these Zexel ECU's. I think this makes me qualified to comment.

Most of the "fixes" proclaimed on the net are well intentioned but wide of the mark. They are targetted at symptoms (like high boost) and not the actual problem (overfuel). A monitored EGT gauge can prevent all engine melt-downs. It's that simple. No end of tinkering with catch cans or dawes valves will make any difference.
 
no interest :)

If there was a straightforward way to swap it infront of say a GM transmission (sm420/sm465/nv4500), I'd be interested. I have an FJ40 set up for a SBC and an sm420 that I want to eventually build for trail use. But as far as I can tell/find, that td42 only 'works' with nissan transmissions. Too bad. Judging by the ride I got in John's safari it would be a good swap.
