Get onto Mudnut I think,He's the man to PM
Is there a resistor or anything that you solder in line to
help convert from 2.8 to 4.2 diesel?

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.
Ok so the project apart from a tune up is complete, I think….
I have kind of admitted defeat for the time being on a tacho but as the one I have fitted functions over 1100rpm I am just going to live with it for now until I can suss out what I am going to do, i did do some tests but had no help at all so i couldn't get a reading off the tacho wires (sorry Mudnut) but seeing as the tacho is working rev wise i assume the sender to be fine..
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.

I am very happy and can now drive very confidently through any police checks with my head held high.

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.
