Nissan TD42 Engine

The TD42 is a straight-six engine produced by Nissan since 1987, known for its ruggedness and reliability, but it is not fuel efficient. Variants include the naturally aspirated TD42, turbocharged TD42T, and the electronically controlled TD42Ti, with power outputs ranging from 61 kW to 160 PS depending on the model. Production ended in 2007 due to emissions restrictions, with extensive aftermarket support available for enthusiasts.

Straight-six

TD42

The TD42 has been in production since July 1987. It displaces 4,169 cc (254.4 cu in); it's a
square engine and the bore and stroke are 96 mm × 96 mm (3.78 in × 3.78 in). Its fuel-injection
pump is mechanically controlled. Early models have a silver cylinder head cover ("Silvertop"),
while turbocharged TD42s and naturally aspirated ones built after 1995 are black ("Blacktop").
[1] Since 1988, Nissan Diesel Industrial Engines also manufactured this model for use in
forklifts; the company building these (and the industrial versions of the TD25/TD27) changed
name to Nissan Industrial Engine Manufacturing (NIEM) in 1995 and became Global
Component Technologies (GCT) in 2015.[18] This low output version produces 61 kW (83 PS) at
2,400 rpm and was still in production as of 2024.[19] Old-fashioned but beloved for its
ruggedness and reliability, the TD42 is not particularly fuel efficient and may be subject to
cooling issues when not properly maintained.[1]

The naturally aspirated versions of the TD42 produce from 115 to 135 PS (85 to 99 kW; 113 to
133 bhp) depending on market, fitment, and measuring methods. It has been installed in the
Nissan Civilian series (W40, W41) since 1988 and the Nissan Safari/Patrol (Y60/61). Original
engines (until 1996) were fitted with 28 mm gudgeon pins whilst from 08/1996 onwards,
Nissan fitted 30 mm pins. The rear seal also changed from a conventional style to a unitized
style around September 1997.

TD42T

The TD42T is the turbocharged version of the aforementioned TD42. It was available from
1993. Nissan revised the piston design to accommodate the forced induction by adding
extended oil squirters and oil cooling the pistons. Crankshafts were also updated to suit turbo
engines. The fuel pumps were upgraded to an 11mm plunger style on these models to handle
the increase of fuel supply needed for the turbo application.

TD42Ti

These engines have been fitted with a factory intercooler and were built from the end of 2002
to 2007. In February 2003, this version received electronic control of injection timing; this
increased the torque output to 360 N⋅m (37 kg⋅m; 266 lb⋅ft),[1] equivalent to a BMEP of 1.09
MPa. The electronic control version was called the TD42ETi by Nissan.[20] Power outputs of
the turbocharged models range from 145 to 160 PS (107 to 118 kW; 143 to 158 bhp)
depending on fitment, model, and market. These are the most sought after model of the TD42
family, having the strongest internals and being factory intercooled. Still highly valued due to
their simplicity and reliability, the TD42 family has a strong following in the overlanding and
offroading markets.[citation needed] Aftermarket support is extensive for the TD42 with many
options available both in OEM and performance applications. Nissan ended production in 2007
due to incoming emissions restrictions; in most applications it was replaced by the ZD30
family.
