I found information on Cruiser-Connection website and am wanting to know what is thought of their "camshaft" and "Motor UP" package instead of turbo'ing the 1HZ as a solution to the sluggishness, and improve the power-band?

camshaft for 1hz engine is sold from Cruiser Connection but is an Italian product made by a little craftsman near my country..
The experiences of a friends of mine that have installated this kit are that engine take more RPM but loose torque..so for me is not a good idea..
turbo kit is great up grade.. but very dangerous
because the great compression 23:1 of engine dont support the great boost..
my experience about 1hz engine is that is impossible to increase power without problems especially if the vehicle is used for long distance..
so you may decide...longevity or performance?

Thanks!
Wonderful info. Hoping to be into a 1HZ soon, and need to know my options for this. Anyone else please let me know what you know, tried....

a turboed 1hz is a proven thing.
Keep the boost low and have fun.
I think most kits boost around 7 psi. Keep it at that.
As Crushers says its your right foot that will kill it. EGT gaue it and learn how to drive the truck
its a landcruiser not a sports car.

Also bought the latest 78 with 1HZ. If I fit a Turbo then it will be the Safari Kit from Aussie. Safari Power
Here's a link to a Italian company making cams for the 1hz.Ferricorse There cam increases lift and not duration, and I think lobe center is changed. They claim it doesn't lose power any where, only increases through out, and better fuel consumption.
I wonder if increased cam lift would help with exhaust temperatures? And would this cam increase power with a turbo'd 1hz?

I have the Turbo Glide on my 1HZ, pretty happy with it. The Troopy isn't a race car, and I drive it as such. 
I recently purchased a Canadian mine truck with an HZ1 diesel, H55F (transfer case???) 4.11 gears with LSD in the rear and was happy to hear the ring gear is 9.5"!
The body is COMPLETELY shot and I bought this truck to turn it into a Rock Crawling Truggy!!!! I'm doing a SOA in the rear and a 3 link coil front.
My question falls in to the Turbo catagory......what is the best, cheapest turbo to mount on this engine? I'm looking for high torque at lower rpms.....say turbo kicking in around 14-1500 rpm. It starts like a dream and runs awesome....
Any information would be appreciated!!
Cheers,

Torque is not a problem with the 1HZ.
A turbo won't help much with torque at low RPM because a turbo needs a load to produce the exhaust pressure that drives the turbo. These two factors start to come in at moderate revs - and it goes from there.
For a "truggy" rock crawler, you want low end, or low gears, or both. Depends on what you plan to do with it.

Thanks John!
I plan on staying with the 4.11's and either adding a crawl box or doubler.....The sneakers I plan to run will be between 36-39" as I do not want to stress out the axles to bad! I hear they can easily handle these sizes. As for staying with the 4.11's they are much stronger then say 5.29's as there is more metal to the pinion and ring gear. As well no need for a lower gear if I am not putting monster tires on!
I'm having trouble identifying the transfer case! I have done alot of research but have found nothing concrete as far as the tcase goes.
I want low end and I hear nothing but great things about the 1HZ motor and H55F trany. I am in the beginning stages of this build and planning ahead.
Questions are free....doing something twice, isn't! lol

...1HZ.
Oops...typo! 1HZ!
Hi everybody
Why need to be bother with all turbo a 1HZ. So troublesome!! looking for a branded turbo to fit into your engine and so on. Just bolt into a 1HD. No headache. solve all the problems. A factory engine will definitely outbreak all the 1HZ with turbo.

If you have a spare 1hdt sitting around, then it would be the way to go. Bolting a turbo on is a lot simpler and cheaper though.
Bolting a turbo to a 1HZ is short run solution. 1HD is more fuel efficiency in long run, you will know the huge difference between the 2 engines. 1HZ with turbo life span will shorten when you have the full boost on it. No direct injection, no fuel compensator. Not designed for installing a turbo.

What is "full boost", 30 psi, 20, 10? Might be better if you defined that a bit more clearly. There are a lot of guys on three continents who have turboed 1HZs over the past decade with good results. The recipe is pretty well known, i.e. which Toyota or Garrett turbos work best depending on what result you want. What do you base your fuel efficiency claim on? I ask because I have friends who run the 1HD-T and I run the 1HZ now newly turboed. I´d like to see the numbers if you have them.
You are right that it is not a direct injection engine, not setup to be turboed from the factory. Nevertheless you work with what you have and modify following proven solutions to achieve the desired results for your application, e.g., I installed the boost compensator, the one setup for the 1HZ by George at All American in the Netherlands.
Hi Wong,
your are probably in Malaysia,easier and cheaper to get 1HD-T,in Canada,they are hard to find and expensive.l have own many HDJ81 and HZJ77,of cause the 1HD-T is a good engine,but if you own a HZJ77 or HZJ75,to get more power out of the 1HZ,turbo with low boost(6,7 lbs) with an intercooler is the way to go.And by the way,a turbo 1HZ is more fuel efficient than a 1HD-T,according to my experiences,after driving both for many miles,across canada,USA and Alaska and Yukon.
RockwildXXX,l am also building a HZJ75 rockrawler,cab is almost finish,lgot new doors and hood from Enns,Toybox and H55 is done,5.29s and ARB lockers not done yet,l am looking for a windshield frame and roof,running 40" mtrs.

Hi volcano cruiser and simonliew
First of all, Thank you for all your opinions. What I mean "full boost" is 18 and above. What you have defined as "good result" as What. Good in speed or power??? Let me ask again, do their engine temperature shoot up when they go for long distance with towing for camper set or some other thing. If they tell you that is at normal temperature, I would have to doubt it.
Let us look at the structure between the two engines. 1HZ No direct injected head, No boost compensator( of course this you can easily installed with one) What the about the piston?? This is the key point with it. 1HD's piston with a so called "Ditch" on top of the piston. Without this "ditch", it will tend to heal up the engine temperature real fast .
Sorry to tell you that I don't have the figure with me concerning the fuel efficiency. I didn't make it on a chart. All of these is go by my experience with the 2 engines. I have a HJ47 pick up with H engine then swap it to 2H then now with 12H Turbo. I own a HZJ75 with 1HZ engine then swap to 1HD. A direct injected engine will be a fuel saver.
No doubt that we in Malaysia are very accessible to all these engine. One whistle, the engine will be at your door way. And Simon you cannot compare the 80 series to a 70 series with 1HZ or 1HD, all their drive lines are different. The weight is also different. You can only compare it with 80 series with 1HZ and 1HD or 70 series with 1HZ and 1HD. We have to be clear that 1HZ is a NA engine not designed for installing a turbo. Unlike a 15B, This is designed for 2 purposes, it can be a NA engine and with a turbo installed to it.
By the way, what is price tag for a 1HD over Canada and US??
