I hope you plan on joining us on a trip at some point mate.... will be good to see.
Yes would like too mate, will have to sort something out at some stage, i will need to get it all run in and settled before i would put it through too much abuse.. lol
Queen’s Birthday Weekend 2015:
Even though the pooy wasn't ready I was away riding shotgun over most of the weekend with the club filming for a TV shoot at Wombat state park, but after leaving Wombat Sunday evening I still managed to complete the bonnet conversion.
I got into some work on the pooy on Monday, as per my thoughts I was able to move the intercooler over just enough to allow me to align the bonnet scoop up with the side of the recess. It meant I had to move the intercooler over a little more than I would have liked but the bonnet scoop was 100% visible the intercooler is not, so I lived with the lesser of the two evils…
After modifying the intercooler mounting brackets I then made up a template of the bonnet scoop and attached it to the bonnet in the correct position, then out came the grinder and the drill, boy was that a butt clenching moment making a big hole in the bonnet, anyway I had managed to get it right and soon had the scoop fitted and looking really good, I even managed to get the scoop smack bang in the centre of the intercooler radiator fins as per the plan. (Normally I’m not very good at this sort of thing) so I was quite pleased with myself, however it would have been easier with a plasma or oxy cutter I have to say.
So having completed the scoop modification and now having airflow over the intercooler I can take the car for another cheeky squirt around the block to see how its running, I had previously after the last drive wound in my fuel screw slightly as it seemed a little low on power, it was now a fair bit better but still only making about 10psi boost. As there was still no smoke I was about to head back home and tweak the screw a little more when the motor cuts out on me and I’m broken down on the side of the road. Confused and a little concerned I soon discovered that my fuel cut solenoid had been deprived of power since I had blown a fuse in the indicators (The live pick up I used for the fuel solenoid must be on the same circuit) anyway, I managed to get it going again and get it home to investigate the indicator fuse problem when I got side tracked and had to leave the garage for other things.

So what’s next?
I have to solve my indicator problem this weekend (Rear left is not working) I then want to re-wire my light bar up because now having had one, I can’t live without it.
Then Next Monday I have it booked in to get a 3” custom exhaust made & fitted.
After that its just a little bit of light tuning and a VASS inspection for the mod plate, followed by a trip to Vic roads to get the legalities formalized. Then I’m done….
Indicator problem solved, it was a simple direct short.
When i changed the BBQ fuel tank to the Diesel tank i had to remove the rear tow bar so i could bolt in the the tank, i did this at night and must have trapped the left hand indicator live wire that feeds the trailer plug between the chassis and the tow frame, it pinched the wire and was shorting directly to the body... That would be the problem then... got rid of the offending wire, replaced 10 amp fuse and lit everything up like a Christmas tree last night with the fuse intact :)
All i need to do now is remove the complete Cluster f#$@ of a wiring job the previous owner did for the spot lights / Light bar and wire in a new switch and harness.
Exhaust Monday, Done :)
I will post up a clip of the grand Finality and a drive as soon as i am happy its all complete and running ok.
Very much look forward to it mate.... as will many.
Lol... just my luck...
I just replaced the front sender for the tacho as it wasnt reading below 2500rpm..
And now with the new sender its doing the same.. farrrrkkkk...
Looks like the tacho i brought is RS... 😢😢😢
That sux mate. . . GRRRRRRR !!!!
Ask mudnut if he knows anything about them....Quote:

I had been in contact with the wrecker who sold me the part and unfortunately (as i expected) it was way outside of any warranty and they could not offer much assistance regarding return, however they really looked after me on a replacement instrument cluster, so I am hoping that as this cluster is identical to my original cluster (Oil pressure gauge & Amps meter Type) I can slot it straight in and everything works, if not that means the speedo is wired differently and I will still need to swap out the tacho component, I will see how I go.
Ok so it looks like i have just hit a big problem... This has just my luck written all over it................
Had my exhaust fitted yesterday and that ended up costing me $100 more than i was quoted, anyway what can ya do, say nah mate, ... No choice, i had to pay it, then on the way home driving back my gearbox started to make some god awful noises when sitting at idle in neutral, if i depress the clutch pedal all the way to the floor the noise disappears, so it looks as though i may have done an input shaft bearing, and if that's the case, its time for a Gearbox rebuild... I can't do this myself, its just too hard to get the box out laying on the ground and i just don't have the cash to get it fixed at the moment as i didn't budget for a frigging gearbox.
Of all the bag over the head punch in the guts a fella can get....
This thread may go very quite for a while now as i am about to go throw myself under a bus... lol
Mate gearboxes come up all the time on face ache if you want me to keep an eye out??
I have had 3 boxes in now with the last one being the best by far... the first started to make noises and vibrate in 5th plus terrible trying to get into gear.. the 2nd was much better but had some leaking issues.. the 3rd has been very good with the only thing being the syncro for reverse sometimes if I have not come to a complete stop it will grind but that is minor compared to previous issues.
I tell ya what though it is bloody hard trying to get a box out from under the car and I have found it easier to remove the engine.
Shout out if you get stuck mate.. I am sure we can muster up some help.
Thanks BA,
I have a mechanic thats a member of one of my 4wd clubs, and after speaking with him today he can take the box out for me and investigate....
I Just cant do it, i am physically and emotionally shattered, i cant face anymore time under the truck struggling.
If the box is stuffed im sure that he could sort me out a replacement, so i will prob take it in tomorrow on the way to work and at least once the box is out, i know what im looking at, after all It will take him 1/2 day to get the box out on the hoist, but it will take me 3 weeks laying on my back struggling on my own.
Apologies for the down tone of my post guys, i really wasn't expecting this and im feeling a bit destroyed today.
Mate I am not sure if you know what I went through but it was hell..... To me a gearbox is a huge pain in the arse but by far the end of the world.
I am sure right now you want to put your head in the sand but dont let it get you down... yes doing it on the hoist is easier but it still is a pain.
You'd be amazed how quick you can get a whole engine out once you have done the conversion.. much quicker than an efi.
I understand you wanting to have it done at a shop... this is a minor set back mate... you have done all the hard work and the gearbox is not hard in a technical way just bloody big and heavy.
I will still keep an eye out for another box.
Keep posting up mate even if it is just to vent as many on here understand your grief and can be great to have a calming word from those that are thinking clearly.
And yes yell out if you need a hand (there are a few on here who are always willing to help) even if its just to chew the fat and look at all my dodgy work...lol
I dropped off my truck with John Nichols, a fellow Nissan owners Club member at Cologne Motors this morning for open box surgery, I guess I should find out what the problem is in the next day or two, john said it don’t sound to serious though.. Im hoping it is something simple, it wasn’t making that bad of a noise this morning, until It warmed up anyway, then it got a little quiter again, all I know is that was screaming like a banchee in there yesterday.
On the Tacho issue, I still didn’t get any joy, the unit Niss4x4 sent was obviously faulty, the needle jumped around all over place, & that was without it even being plugged into the sender yet ! so I called them and said its cooked & pictured , is their answer to a free replacement Tacho unit… I doubt this one will work either, I mean look at it…. I'm not holding my breath… ..
Attachment 58984
Bang Head I'm very disappointed, as they have been awesome upto now, If this don’t work, I will just have to take it to patrolapart to get it working and get shafted in the wallet again.. $$
C’mon Andy, think happy thoughts !!! lol … Ok …..I am still hoping to make my VASS and get vic roads sorted by 29th June….. Maybe….. only if my luck changes
While i was going through my build i kept thinking the worst at every turn and sometimes it was justified but many it was just me being stressed and down on myself..
You have done very well so far and personally i think your set backs are minor considering how big a job this is.
You might be surprised at that tacho..
Keep positive and maybe take on my motto for this year... onwards and upwards.
Andy is there any updates mate??????
Sorry i havent posted for a while, not really had much to report, but today i can say that the pooy is just fresh out of the workshop yesterday evening.... I can breath a sigh of relief...
It turned out to be a buggered Spigot bearing and broken / loose springs in the clutch plate, the gearbox is fine. Phewwwww ...
So i have now had an exceedy tough clutch fitted with new spigot bearing and thrust / throw out bearing... I should have just done this in the first place. Although the clutch seemed fine on inspection it was obviously about to die and maybe the alignment problems i had during the engine installation onto the gearbox finally killed it.. anyway.. Its done i got John (The mechanic) to do an oil change in the gearbox and the transfer case while it was on the hoist.
VASS is booked in for next Monday Lunchtime this should be my final hurdle, it should go through no problems the only grey area is the TD05 turbo, but its set at only 8psi at the moment (factory std) and the TD05 was an option for the DTS turbos fitted to patrols sooooooooo i am kinda hoping the engineer sees things my way ! :)
See........ happy days mate.. yes another expense but one that should have been part of the build.Quote:

Glad its coming together... you'll be wheeling in no time!!!!
I finally got back outside last night to swap out the Tacho units again, and i still have a problem, the tacho will not read and jumps around all over the place without the engine running, so im starting to think there is something wrong with the wiring..
I am going to have to re-think this as i cannot have 3 faulty tachos.
1st tacho - Sits on zero and wont read any revs under 3000
2nd tacho - jumped around and spiked would not read (Engine Not Running)
3rd tacho - jumps around then settles around 1500 rpm (Engine Not running) Then with motor started reads increases in revs but only from 1500rpm, so idle speed is like 2500rpm
Out of interest i then put the petrol tacho back in, this sits on zero and reads with motor running, but only above 1200rpm, then reads normally, the needle then hits zero at idle..
LOL who would have thought two wires can cause so much pain.. lol
Sounds to me more like a faulty sender....... If I still had the other engine here I could have ripped it out for you.
See if you can at least loan one... some shops charge a re- stocking fee for using parts for testing?
I am not sure how to test the sender you have in there at the moment as that is for the electrical nuts??? maybe try messaging Yendor?
What you're describing with the petrol tacho is what the TB45 conversions seem to experience when they connect the TD42 sensor to the petrol tacho. Nothing below 1000-1500 then shows normally.
I thought the same BA, so i did change the sender and had the same result, also thus eliminating the sender.
I have another idea, i may run the two wires up from the sender and connect them to crimped eyelets and secure the eyelets behind the relevant screws behind the tacho, thus bypassing the plug.
At the very least i t will eliminate any bad solder joints in the wire connections in the plug.. I will give it a crack.
Attachment 59136
Yes the petrol tacho thing has thrown me a bit because i was under the impression it wouldn't work at all.. lol
I will solve it eventually... lol
I bypassed the plug last night, I attached the 2 eyelets to the wires and then fixed them directly to the PCB of the tacho where it screws into place.
This also didn’t work, on all three tachos i have. so I am at a total loss… I must just have 3 RS tachos, I will now go to Patrolapart for them to fit a working tacho, I am not prepared to spend any more time on it, i must have had the dash apart and the cluster out 30 times now, I will be really disappointed with Niss4x4 if they have supplied tachos that don’t work !
I will just run with the petrol tacho for now as that reads over 1100 rpms so at least that's something, better than nothing
correct me if i'm wrong but dosn't the td42 tacho pick up from the alternator ? and the petrol from the dizzy/computer? have you got the pick up from the right place ?
i had to replace the speedo and could only get a petrol cluster... so i tested it whole b4 i pulled it apart, tacho didn't move at all. but thats a petrol tacho in a diesel.
Hi Garret,
The EFI tacho it picks up signal from the ignition coil through the ECU, but i have bypassed all of that and run 2 new wires from the pick up point on the TD42 motor, then i changed the tacho gauge/ cluster to suit a diesel motor... The tachos work on the same principles i guess, but having wired it up correctly with the required equipment to tried and tested methods with no good result, i am now at the limit of my ability so i will have to put it in to patrolapart and see what the outcome is from there.
As a last ditch attempt to solve my tacho problems, does anyone on here know if the tacho from a series II GQ patrol 2.8 is the same as a TD42 Series II tacho, the two tachos i got supplied from the wreckers are out of 2.8's THIS IS MY LAST IDEA ! . LOL
Help... Please.. Anyone.. lol
Hey mate I can't help at all but just letting you know I have been reading this whole thread and following your little journey...
Stick with it mate, you are too far to throw it in now haha!
Get onto Mudnut I think,He's the man to PMQuote:

Andy, further to the PMs I sent,
My computer screen is so stuffed
that I can't get clear pictures of
the TD42 wiring.
I have looked at the Haynes
Manual and on Page 12-18.
It is vague about identifying
which engine it is for.
It shows that the sender has
two wires to the gauge and a
third connection to earth in parallel
to the fuel, oil and temp gauges
via the circuit board.
When you tried the two straight
wires to the tacho, did you
disconnect the original
wires from the
plug to eliminate any fault.
Thanks for the above Mudnut,
Yes the original wires are no longer connected at the cluster plug / pcb.. (The EFI only had one original wire (Yellow & Black) in pin 12, this was removed as it went to the Coil where the original petrol pick up was located.
All other gauges in the cluster are working 100% which indicates that the live and earth parallels are ok.
I have an older laptop here that i was going to use in the garage only that you are welcome to Craig...Quote:

So here it is the good news……
I had the car engineered by VASS successfully, and thus pooy conversion was passed by the engineer and a modification plate fitted, so before anyone had a chance to change their minds, I then headed to VicRoads and handed a copy of the engineers report to the customer service people who then came out to observe the engine number in the car and the modification plate attached.
Result - My truck is now 100% legal 4.2 turbo intercooled diesel with 3” exhaust, bulbar, winch, light bar, roof rack, rear draws, 33’s and a 2” lift weighing in at 2550KG.
Attachment 59306 Attachment 59307
I am very happy and can now drive very confidently through any police checks with my head held high.
Attachment 59308
Ok so next is some final tweaks, I have now fitted my T boost controller and my straight through 3” exhaust section (removing the center muffler) and will be giving it a dyno tune this weekend so I can ensure that the thing is running as well as it can be on a standard pump.
Brilliant stuff mate....... the hard part is over and now its just a bit of fettling to get the small things sorted, oh and of course the never ending maintenance ...lol
Woohoo! Congrats mate!
Awesome stuff there mate. Who did the engineers for you mate? As for the tacho. The is a mob in ringwood who do speedo's etc etc . Cant remember who they are though. Might be worth ringing them and having a chat...
Edit : they are called Ringwood speedo service...

hey it sounds like you have had your fair share of hassles . really excited to hear it is a goer. I just got my engine back from the engine machinist in pieces ,so the assembly begins. Good luck with the tacho, i'm sure you will suss it out .Are you happy with the performance. Please say yes i have to look forward to mine getting finished .
Ok, so i had my first trip up to the Nissan Club property this weekend, i was a little nervous driving it all that way for the first time, and being a new motor on a freeway i had to vary my speed and keep giving it full peddle to bed in the rings.
The truck ran great no problems at all apart from some fuel needed (I think my 10 mm pump is ok but at speed and full boost she struggles to put the fuel in.
I have had it tuned but they never hooked up my boost T so i think i will put that on and give the fuel screw just a little tickle and see if ia cant get the boost up to 18 psi and give it a little more diesel. if not i will have to live with it until i can afford a pump upgrade.
Having checked the oil and coolant level when i got there and then again when i got home, i found it wasn't leaking or using any oil or leaking any coolant at all..
Overall the truck sounds awesome and loves the low range torque.
I didn't get any pics or video as i was just doing a break in run. i will however put up a movie of it in action as soon as i can.
I will be fitting my turbo timer and boost t this weekend and doing my first oil change.
