Turbo-charging the Toyota 1HZ engine is simple but can result in blown pistons and overheating. Here is a remedy I found to be simple and effective. Filmed in the Central Kalahari Game Reserve. If you like Andrew's videos, CLICK HERE: / andrew_stpierre_white

Andrew mention the pistons being thin at the top which can blow holes in them. The other cause of piston problems is the 1HZ was never designed to run with a turbo, the next gen engine, the 1HD not only had better pistons, it had oil passage ways that squirted oil to the underside of the pistons to aid the cooling of them. Don't fit big turbos on a 1HZ, they just aren't designed to have them.

@SamTheSuave Yes...has increased consumption about 20%.. but if you have more horses, you have to feed them!

@markwinter7511 4 года назад

The perfect combo it seems is to put a 1hd ft into a 105 series. Much easier swap without all the electronics of the fte. What a great pity Toyota didnt make them like this today they would be priceless.

I have a 105 motorhome with a HD FT. Love it.

@4xoverland 14 лет назад

@SamTheSuave Good question. This vehicle, the 105-series Land Cruiser, was only ever built with this motor, or the equally reliable but absurdly thirsty 4,5 EFI straight six. This is such a great chassis, but only built with engines designed for the Third World. That is this vehicle's weakness. Hence the turbo mod. There is even a gearbox upgrade now available, so it can cruise at 120kph @ 2400rpm, instead of 3000rpm. The 100 series was built with the 1HD-FTE but has independent front suspension

@TheMr0450 4 года назад

We need closure on this subject Andrew.. did u have success with the product. And would you turbo your latest HZJ105 ? The one you are building right now.

That's interesting about the 76 being still fitted with the 1HZ in SA. Over here in New Zealand, the same wagon is fitted standard with a "1VD FTV", or commonly referred to as the 4.5L V8 inter-cooled turbo diesel. Great video - can't wait to hear of your experiences since the turbo charger installation.

@Land_Cruiser_40 5 лет назад

It was such a mistake to not offer the 1HD-FTE in the 105 chassis. Cheers

Had that car on my trips in Austrlia - loved it! Really comfortable, reliable, really good in rough areas - and as you said - power could be a little more ;-)

@SamsMotors 14 лет назад

@4xforum Ah I see, my mistake. They look very similar, though I had no idea Toyota put IFS on the 100 series. I would have assumed that all of their large 4x4s had two solid axles. Still, it'll be interesting to see how much of an improvement that LPT will make to your performance, and whether or not it will affect your consumption.

@wormfood868 13 лет назад

@rdenecker I can't say authoritatively but my understanding is that the V8 is more picky about fuel quality, in particular the injectors are prone to failure if the fuel is bad. Plus of course the familiarity of mechanics and existing stocks of spares are compelling reasons to keep the old motor in a place that's so hard on vehicles.

@youngfisho 9 лет назад

The reason why Hzs blow pistons is due to the AFR they are tuned to. To maintain reliability they need 22:1 to be safe. THis has been proven over and over. A well designed hi flowing turbo will ensure this AFR is maintained. Boost will not destroy a hz. But overzealous fueling can and will. I would strongly recommend checking out gturbo and xxi industries. They are the leading R&D tuners for turbocharged HZ's.

@chas2can124 8 лет назад

+youngfisho Hey. Thanks for the info. I spoke to Andrew at xxi a few months ago about getting an AFR tune done. He advised the 21-22 to 1 mix is ideal but I am in Sydney. My 1HZ with Denco Turbo and my Boost Tap is booked in for AFR tune at Total Care 4WD on 8 Feb. Adjusted the fuel input to achieve 14PSI but warned to get the AFR done ASAP. Should I be aware of anything more before I drop the girl in? Cheers.

@youngfisho 8 лет назад

+Chas2Can gturbo's are the recommended turbo to tune to this afr, they spool early and require less pre boost fuel than other turbos. Making sure your injectors and pump is spot on, and a boost compensator wouldnt hurt either.

@chas2can124 8 лет назад

Fair enough. Can't change the turbo just now. GTurbo looks nice. Mine (not my choice is from TurboGlide Wollongong) l Gotta live with it. 100K km and haven't done the injectors since purchase (316k km now). ACK a boost compensator will work but that's another $2-3k. Will speak to the guys to perhaps replace the injectors prior to AFR Dyno. I'm doing the fuel filter prior. Thx for the help. Peace.

@youngfisho 8 лет назад

+Chas2Can a new pump with boost comp is 2400 bucks, to compensate the pump you have 1000 bucks or less. Injectors would definitely be a worthwhile purchase

@chas2can124 8 лет назад

Cheers Bro.

@MaryJane-qc6pb 11 лет назад

So basically.. If you're going to turbo charge, do it WHIT cooler. Boosting any diesel engine you are fine if you keep under 0.65.-.0.7 bar!!!! It will give you 50%+ more hp and keep running as it was ment to be. YES I'M ONE OF THE GRAZY om606 SUPERTURBO DUDES FROM FINLAND. Happy tuning and keep them smoking :P If you need elements, PPDIESEL in Finland will help you

@SamsMotors 14 лет назад

Looks lovely, (high praise coming from a Land Rover fanatic!) though would it not have been better to simply purchase an already turbocharged diesel, such as the 1HD-T (165bhp, 260ft/lb) or the 1HD-FTE (201bhp, 317ft/lb)?

@AndreyYeltsov 7 лет назад

Isn't is easier and more reliable to swap 1HZ with 1HD? It is a bolt-on swap.

@jaywoolford6874 Год назад

Please change the title of this video as there was no real explanation of the serious issues of putting a turbo on a 1HZ motor. You can avoid blowing holes in the tops of pistons simply by changing the fuel air mixture (yes I know it doesn't have a carby however they do run a computer which you can break into and tell it what you want from it) and are you running a pyrometer to monitor EGTs. What intercooler are you using if using one at all? There are so many unanswered questions here.

@JackFN_VR64 14 лет назад

@4xforum My apologies for asking the following question, I am sure this has been dealt with before, but why, in SA, is the 76 only available with the 4.2 and not also the 4.5 V8 turbo diesel? I struggling to find an answer, a few links or a quick explanation will be greatly appreciated.

@madcat4563 4 года назад

Ok so it's been 8 years. But the answer is that Toyota is kind of hesitant about bringing new Toys to SA. Their excuse was originally that our diesel was not good enough. In 2005 50ppm became available but only a few places had them and in 2012 it became mainstream. We still got the V8 200 series in 2008, Wtf. (Probably because it is a luxury vehicle and people would want the best fuel). The 70 series is more utilitarian so people would have probably thought 500ppm is fine. There is no definitive answer, this is speculation. But whe finally got the V8 in 2013 after numerous delays.

@JackFN_VR64 4 года назад

@@madcat4563 Haha I don't even remember writing this post. Yeah I suppose there is an element of truth to the fuel excuse, however I reckon the average South African doesn't give a hoot about ppm, they fill up with whatever is the cheapest. I believe now the major factor was and still is, is that Toyota SA is full of tricks when it comes to selecting specifications for the SA market. If you compare specs with what is available in comparable vehicles in eg. US, Australian and Japan, you will often find South Africans get the short end for the same or even higher prices. For instance, the LC200 is/was available with more luxury features in Aus, and in Japan you could get LC200 with the adaptive suspension you find in the LX570. The LX570 (2020) now is about 1 million ZAR in Japan compared to 1,5mil + currently in SA. Same thing with the 2020 corolla hatch - 2lt manual versions, sport versions, AWD versions, hybrid versions, heated leather seats, sun roofs, led lights and so on vs 1.2t with cloth seats and cvt.

@madcat4563 4 года назад

@@JackFN_VR64 I think that it is not only Toyota that specs vehicles diffrently. Car manufacturers spec a vehicles for what the market wants or what is popular. Don't forget about nissan that kept selling old style Navaras for 2 years in SA and the rest of the world had the new one. Then there is the nissan Hardbody that fails the NCAP test wich angers me is it does not get a lot of media attention Here is a test between a brand new rattle trap Sa spec hardbody Vs.
