How good is Toyota 1HZ engine?
1HZ’s in standard form are very reliable things. Half-a-million Km’s wouldn’t be unheard of for a routinely maintained 1HZ. Our undergound fleet of HZJ trayback utes and 105 series cruisers get used and abused everyday and take it all in their stride. The chassis and bodies rust out before the engine dies.

Also, we were reassured by the fact that Toyota did produce a factory turbo version of the 1HZ – the 1HZ-T – that was fitted to Coaster buses in Europe, before the advent of the direct-injection 1HD-T. If the worst happened – piston, rod or bearing failure – there were plenty of upgraded bits available, Al reasoned.

Which is better 1HD-T or 1hdft?
I have had both of these engines and by far the 1HD-FT has more power and runs better than the 1HD-T. The FT has 24 valves instead of 12 and makes a huge difference on the power it produces and when it produces it.

What engine is in a 75 series Landcruiser?
USED 75 SERIES The twin-cam 4.5-litre petrol engine was almost overkill in the 75 Series, while the diesel slogger was one of the best low-speed, off-road engines ever made.
