A Company I worked for in Cairns turbocharged around 600 Landcruisers, 1hz and some Hi Luxes during my time there. Most of these were for a Copper mine in Irian Jaya, Indonesia, and while the turbos were fitted mainly for altitude compensation, up to 15000ft, so the boost levels weren't meant to shread tyres, the reliability was awsome. We never had a problem with any vehicle we turbocharged because the work was done properly, plus the 1hz is a great engine, as is the TD42 for that matter. I am sure there are some horror stories out there, but there is usually a very good reason.
100% WILL split/crack the piston crown on a 1HZ aftermarket turbo build. Even with a really mild tune they do it. Head gaskets have always been an issue with the 1HZ as well as cracks between in the centre of the head. Sad really since the block material is really good. Ive never ever seen a broken ring land on a turbo'd 1HZ, only dozens of split pistons. Only time ive seen broken ring lands is when the "locals" used a petrol rag over the air filter to start them instead of replacing glow plugs. Over all they respond well but dont last, even when "built" for a turbo. Better off getting a 1HDT, much better option in every regard.
Havent had an issue after 14 years on dads 1hz turbo, do it once do it properly, and dont drive like a "P plater" flog. Id love to swap a 1HD-FT into my hzj79 instead of turboing my 1HZ.

This is really interesting. When you turbo a 1HZ, do you take the engine out of the bay? I have an NA 1HZ and have always wondered what this kind of work would cost?
Yeah nah, I wouldn’t rebuild a turbo 1hz. Just slap a good quality set up with a big intercooler. Get a dyno tune who’s done it before and don’t let it get to hot. If it blows up fte swap lol

Hey mate love your work, any chance you can do a video on upgrading 1hd ftes for more power, and are ARP head studs a good idea?
