Turbo fit to high mileage TD42
Hi all, Am looking for some info, I have recently come across a complete bolt on turbo set up at a reasonable price for my TD42 GQ. My old girl has quite a few Ks on the clock but is in excellent mechanical condition. Injectors and pump are both fresh. Just wondering has any body turbo'd a high mileage one? Did it work? Have seen aftermarket turbo ones with 700,000km + still going strong. Obviously a motor rebuild would be the way to go first but am short on time and funds. Any info appreciated, Cheers

I think Berrimah Diesel turboed a high mileage GQ with no problems whats so ever.
From memory it had 500,000 k so just run in really, they may have it on there web site.
Its their daily driver ATM
04 ST 3lt auto, not enough Mods to keep me happy, but getting there

mine has 350,000 on and I plan to turbo soon. Just going to get a compression test done and if all good go for it! I'm not trying to create a monster so it wont stress an old motor to much.

G'day Bushy,
I'm going to be way, way out side here,,,,,,,,,, but,
why oh why would you want to fit a turbo to God's gift to 4WD?
Had one and swapped it for a later 3.0CRD with turbo and have never stopped regretting it.
4WD tractor in low, crawls up creeks, rocks, sand, swamp, you name it and you're talking about swapping that for high revs, flat strap no low torque output?????
You've got either high revs. turbo or low revs grunt as your options, seems to me.
Sorry for an old fart's opinion
regards,
Col

You don't lose any of that low rev crawling ability with addition of a turbo on a 4.2. If correctly sized the gains will be very worth it. You are comparing to very different things with the crd and trusty old 4.2. It's the old saying "there is no substitute for cubic inches" , you have got to experience this with the 3.0 compared to the 4.2 and as you know the poor little 3.0 needs the revs to push around a 3t car.

My 93 TD42 is a silvertop and I fitted a Gartett turbo at around 360k. I did a compression and leakage test beforehand and my mechanics were happy with the results. I've done about 60k with the turbo fitted now and I haven't looked back. My turbo is not intercooled and boost is set to 12.5PSI.

Hi Col and Newbie, I gotta go with newbie on this one mate, I have worked on and driven plenty of turbo 4.2 GQs and you don't lose out at all. And you definitely can't compare it to the 3.0ltr, my personal opinion is that nissan shot themselves in the foot by not making a big six modern diesel for the GU and leaving the 3.0ltr for the Navara or better yet putting another two cylinders on the 3.0ltr!!!

Hmmm nothing in this post makes sense?? Sorry.
With a turbo it gives you better low down grunt and don't need to have it revving flat strap. Is that how you have to drive a 3.0 crd. I now have more grunt and power than a 3l crd now.
The turbo gave my 4.2 a massive torque injection and mid range pull (1700-3000rpm). It actually doubled my power at the wheels. I never rev it over 3000rpm. Over taking is great now.
When rock crawling the turbo never kicks in unless I stomp it going up a hill that's muddy or sandy. It is the best mod you can do for a 4.2 NA. Did mine at around 285,000km.
Cheers.

Winnie and I did a idle test just for shoits and giggles in the high country.
Was a 15-20 degree rocky incline
Mine a stock as a rock td42 and Winnie's td42 turbo 3" exhaust and high flow filters.
He blew me away.
No wether this wa due to the extra flow or the age (mine 500 ###km and Winnie's 300###) I don't know but the proof is there..
