The 1HD-T is a 12 valve 4.2 L (4,164 cc) straight-6 SOHC turbocharged diesel engine of direct injection design. Bore and stroke is 94 mm × 100 mm (3.70 in × 3.94 in), with a compression ratio of 18.6:1. Output is 164 hp (122 kW; 166 PS) at 3,600 rpm with 361 N⋅m (266 lb⋅ft) of torque at 1,400 rpm.

Are 1HZ engines good?

1hz engines are not. Both are very reliable but the 1hz is under powered. Newer diesels make more power but, in my book, the mechanical 1hdt is the best Toyota diesel because of its epic simplicity, reliability and usable power.

How much boost can a 1HZ handle?

The 1HZ can crack pistons from too much heat, they will run 8 to 10 psi boost safely without I/C but with one safe around 12psi.

Can you supercharge a 1HZ?

Bullet have developed an all new Supercharger system for the 1-HZ 4.2ltr Diesel using the S5 335 Sprintex Supercharger. Our new Patented 1HZ Supercharger System has been fully designed, manufactured and durability tested in Australia. Power and torque is up 40% vastly improving towing ability.

How long do 1HZ engines last?

The 1HZ is a 10,000 hour engine before major rebuild (mine use), in real life 500,000 kms with no turbo, guys with turbos are getting 200,000-300,000 kms with no problems and still going – there are always exceptions to the rule of course.

A 1HD-T would benefit from better intake runner transition from the plenum, port matching of intake runners to the head, porting of the head, port matching exhaust ports to manifold etc. None of it in standard trim has been optimized for maximum performance Click to expand… Did you do all this already?

Where is the intake charge stored in a 1HD-T?

The theory is there is adequate intake charge are stored in the plenum all the time so no cylinder is starved of air. A 1HD-T would benefit from better intake runner transition from the plenum, port matching of intake runners to the head, porting of the head, port matching exhaust ports to manifold etc.
