Turbo a 4.2 Nissan

This truck is set up for competitions
102000Ks hasjust been fitted with a new HD clutch
The competitions in NZ are normaly of a slower speed similar to your tough truck series.
The reason for the questions are that there is not a lot of options or info in New Zealand

AXT are in Dandenong Victoria, no website.

They are all good,

Fuel Aneroid you mean??

Only really good if your going High Boost 12+psi on an after market Turbo.

Well thats what I was told by ARB why Im not runnin 14psi!

Some call it that, and it does allow fine tuning of fuel metering of low boost engines, ie TD42 GU (7psi) and given that most after market system restrict boost to 10 or 11 psi, it is still wise to fit the boost valve, purely for clean air emissions regulations. (particulates).

I was quoted by Rankin Diesel in Bayswater $3000 to do Fuel aneroid and fuel pump.

I nearly soiled my pants on the spot..
but others ahve said he isnt cheap.

Im going to BJ Diesel in few weeks to get Injectors done. need $$ first.

Truckster,
Sold the engine no problem, it's now going to another life as a turbo intercooled motor, after what it was the old girls in for a bit of a shock.Keep the shiny side up

Good news!!!!!!

Again extreme thanks for the offer and deal.

to others, this bloke is very worthy of dealing with, and a real gentleman.

Yeah I've heard that Rankins are a bit hot price wise, thats partly why I stopped going there many moons ago. Heavy diesel shop behind Truckcity in Campbellfield, M&J or something like that, specialises in big diesels, ie Cat, GM, Cummins etc, but he himself has a GU ute which he has tricked up. Does all pump and injector work in-house, and by all accounts, it fairly rocks! Will be speaking with him in a couple of weeks when I get back to work. He has a theory regarding Nissan injector pressures, so will sound him out.

Desert, I love you long time if you get the details..

Sort of keen to get this bleep sorted, out my fuel econ is rediculous!!!

Only $1 luv U long time truckie.

Ive had quotes from 3 places to redo fuel pump.

rebuild and all, cheapest was $2200 :( but that was west end diesel and included setting the thing up for the turbo PROPERLY.

Martyn, what range of temps. does your engine operate through??

Desert,
Around town usually around the 200 degree C, 250 degrees up small hills, I never turn the engine off unless the temp is around the 100 degree mark after a run. With the camper trailer on the back I rarerly take the exhaust temp over the 450 degree, 475 degrees Max without changing down, from what i've seen it's easy to get the temp higher than this without tring to hard, I was surprised, I think that 600 to 650 degrees C is where things start to melt or that's what I base my judgement on. As usual Desert others will have other opinions but this is the way I choose. Keep the shiny side up

Thanks Martyn, that'll help me out with selecting a pyrometer.

Desert,

try VDO, I have a VDO Pyrometer to go into mine, going to mount it in a Dashpod, with Boost guage, and Temp Guage.....

should look good!

Hi Colin
Tell me more, this sounds like a better alternative.
The fact that the pressure is constant must be kinder to the engine plus make thye truck more user friendly when the need to walk over obsticles at or just above an idle and still have the extra power on hand. I assume this unit is belt driven, where is it mounted?

Told ya Col was the man for the blower.

Colin, you got any photos etc of your setup??

If you would write up a bit of a story, and some pics, Id like to up it to gqpatrol.com for an info/alternative thing for people.
Email it to me.

I have a Sprintex Supercharger fitted to my 80 series 4.2 litre diesel and concur with all of Col's comments bar the fuel economy. My consumption did increase but I think that's mainly due to me using the extra power for acceleration and leaving the traffic behind. It's also a little harder to find mechanics with familiarity. Everybody seems to have a little turbo experience but few have dealt with superchargers. With no adjustment to boost on a supercharger other than pulley size, I tend to think that my fuel setting is still a little high. I don't blow smoke but I had the injectors done and the vehicle dyno'd at the same time, (about 150k on the clock, now 160k) and told the dude that I was looking for an improvement in economy but no joy.

What implications are there for rich or lean running? Any info appreciated.

Hi Truckster whats your email adress. Col

Colin, out of interest did the fitter of the supercharger drop the sump and do a bearing inspection prior to the work? And what sort of warranty did they offer you?

Hi Desert no the sump didnt come of, i have had the vehicle from 90,000ks and know the prior history i have serviced the vehicle religiously and knowing the td42 is good for over 500,000 had no hesitation. I got a 12 mth warranty on parts and labour. Col
