An engine developed by toyota in 1990.

The strongest and most reliable engine ever produced by any car company.

Although it doesn't make a high amount of KW, it's still very capable of producing enough power to tow Nissan Patrols out of the bog time after time.

With a turbocharger added, this engine can produce 17 times the power of a TB48 With 2 TD42s attached to it.
Wow! That 1hz Landcruiser just went through the track that every patrol couldn't get through.

What an amazing piece of technology.

Get the 1hz mug.
6cyl Toyota Diesel engine found in vehicles such as 'land cruisers' Every cunt with an Akubra with cattle ear tags on it owns one. very problematic engine as it's top speed from factory is an outstanding 73km/h. But if you're towing your horse float with the sign 'caution horses' on the back then the speed drops down to 68km/h. Some people put an after market turbo charger on their 1HZ so they can arrive at pony club a bit quicker, when doing this the 1HZ shits it's self when any higher than 2.1 psi is reached.
My 75 series is running a 6inch lift, 35s, front and rear lockers, 4inch snorkel, and -44 rims but is N/A as I don't want to strain the 1HZ

Quick! If we are going to make the Tamworth country music festival we have to leave now! The poor 1HZ will only sit on 74Km/H
