nissan patrol 4.2 turbo diesel

Fit 3.0Di immediately....

Farmer, lots of info in the archives, try a search first, then maybe come back with specific questions, save reinventing the wheel.

Steve - I also have the 4.2. Very simple answer :
The right foot is directly connected to the fuel tank.
Keep speed under 100 and drive it for the reliable truck it is.
Consumption around 12l per 100klm. With 1.4t camper - 16l per 100 klms.
Push it to 100 and over, and economy suffers. My experience.

Hi Steve,

I also have a 4.2 T Patrol and have done many modifications to improve performance (not too improve economy though). I now run at about 90kw at the rear wheels as opposed to the standard 65kw. The guys at MTQ toowoomba have done the last increase in power and I have been happy with thier efforts, although I am sure their is other mobs offering the same power-ups. My uncle had his 4.2 T Patrol revved up by MTQ also and is running 96kw, so there is a bit of variance to the outcome of thier work but they would be a good starting point.
One thing I will suggest is to do your homework on whoever you decide to let play around with your truck as these things tend to run hot when being pushed in standard form and tickling them up does not help this.
In essence a 30 - 40% increase in power and torque is not out of the question, if you think you could get away with less than this increase then start with the 3" exhaust and dump pipe at the back of the turbo. This will give a noticable increase, but if you decide to go for the extra neddies then the exhaust modification will need to be done anyway for futher enhancements. If you are in Brissy and would like to know more then supply me with an email address and I will arrange to catch up and maybe even let you have a drive of my truck to see the difference. This is subject to how much of a ratbag you are of course Hahahaha.
Best of luck Trevor.

Motsons of Brisbane do a power up for the Nissan 4.2rd's.

I had mine done with 30% increase in power and torque but no better fuel economy. It's done more than 120,000 now since power up and is still just as good today. All that's been done since is the tappets as per service requirements etc.
You cannot use the gas diesel blend as these vehicles are indirect injection, I believe that you must have direct injection for the gas bit.

Stay at the legal limits and the truck will perform great with to my mind reasonable economy.

I have some relatives that own a few very respected diesel injection and fuel pump etc mechanical shops. They do work for any diesel and alot of diagnostics as well. The 4.2's they have worked on are unbeliable, the extra power and economy they can get is great and worth the bucks. They believe that they have perfected the injection and fuel pump supply for the 4.2s, if you like let me know and i will pass on the info and you can enquire for yourself.

One small problem i'm in brisbane and the comapny concerned is Highway Diesel at Coopersplains. Contact them on 07 3277 5805, they may ne able to give you some advice on where to go in Sysdney for some work, ask for Craig. Tell him Aaron recommended him.

Remove top cover off aneroid valve(four screws) and rotate diaphragm clockwise to increase fuel. Make sure you mark the diaphragm's original position before you start playing with it (don't go further than 90 degrees). Also adjust screw in on aneroid top cover to increase fuel down low. You will be surprised how your fuel economy will decrease and power increase. If you are unsure about this get a diesel shop to do it, and maybe adjust your injection timing if needed. Fit an EGT to monitor your exhaust temp so as not to create a meltdown.

Farmer,
MTQ have agencies in Sydney, West End Diesel in Wetheril park I think. They are good but want to rebuild your pump $$$$, OK if its older but unecesary if new.
I had mine done in Toowoomba and very impressed, will definitely go back next vehicle. Worth the drive.
My main advice is buy a package not just exhaust etc etc. I spent money on magic tune ups and then pump and injector rebuilds and all wasted.
MTQ do turbo internals, tune and exhaust and together it really works, to the mark of 30% increase in both pwr and torque with economy up too.
Done 180'000km now still going well

Wouldn't mind knowing if anyone has gone the gas injection route on this engine also. Diesel Gas Australia have come to market with a safe looking system with map sensor et all- anyone with real world results though???

Farmer, JR's reply covers most of what I have done to my 4.2 TD (Nissan), have also just fitted an I/C, mainly to help fuel economy. Still doing figures atm. Any other questions, please ask, only too happy to answer.
