Chronology

Predecessor Nissan SD engine

Successor Nissan QD engine

Nissan ZD engine

The Nissan TD series is a series of diesel engines manufactured by Nissan. All TD-series engines
are inline engines; most versions are four-cylinders aside from the six-cylinder TD42. They have
cast iron blocks and crossflow heads; the combustion chamber design is a swirl-chamber
design with indirect injection and a gear driven cam.[1] The valves are pushrod-actuated, and
the engine has two valves per cylinder;[2] the camshaft is driven by a set of gears.[1] Of a
simple, somewhat old-fashioned construction, the engines are generally durable if not very
powerful.[1][3][4]

Straight-four

TD23

The TD23 has a bore and stroke of 89 mm × 92 mm (3.50 in × 3.62 in) and thus displaces 2,289
cc (139.7 cu in).[5] Its compression ratio is 22.0:1. It is the least common of the TD series
engines, and ended production around 1995.[5][6]

Outputs[7]

76 PS (56 kW; 75 bhp) at 4300 rpm

151 N⋅m (15.4 kg⋅m; 111 lb⋅ft) at 2200 rpm

This engine was installed in the 1987-1992 Nissan Pickup (D21); it was also used in the 1986-
1988 E24 series Nissan Caravan.[6] It replaced the earlier SD23 engine in Nissan Atlas 1-ton
trucks in 1986.[8]

TD25
The TD25's bore and stroke are 93 mm × 92 mm (3.66 in × 3.62 in), giving 2,494 cc (152.2 cu
in). Period reviewers referred to the unit as "thoroughly viceless" and "a bit bland".[3] This
engine was also used by JASO, the Japanese Automotive Standards Organization, for their
diesel oil Detergency Test procedure (M 336:1998) from 1998 until engine assemblies and
parts became unavailable in 2009.[9][10]

82 PS JIS (60 kW; 81 bhp) at 4300 rpm (JDM)

75 PS ECE (55 kW; 74 bhp) at 4300 rpm (Europe)[11]

166 N⋅m JIS (16.9 kg⋅m; 122 lb⋅ft) at 2200 rpm (JDM)

160 N⋅m ECE (16.3 kg⋅m; 118 lb⋅ft) at 2200 rpm (Europe)[11]

It is applied to the following vehicle(s):

It has been used in the 1990–present Nissan Cedric YPY31, the Nissan Navara D21 series, and
the 1-ton Nissan Atlas F23 series from 1995 to 1999 (sold as the Cabstar in Europe and certain
other export markets). It was also used in the Nissan Caravan/Urvan (E24).[3]

TD27

Bore and stroke are 96 mm × 92 mm (3.78 in × 3.62 in) giving 2,663 cc (162.5 cu in). Maximum
power of the naturally aspirated model is 85 PS JIS (63 kW; 84 hp) at 4,300 rpm.[12] A
turbocharged version of the TD27 was introduced in 1988.[4] A low output version of this
engine intended for forklift use, producing 38 kW (52 PS) at 2,300 rpm, remained in production
with GCT (Global Component Technologies, successor company to Nissan Diesel Industrial
Engines) as of 2024.[13]

This engine was also exported to the United Kingdom and fitted to LTI's Fairway series, coupled
to manual or automatic transmissions also supplied by Nissan.[14] The low-stressed naturally
aspirated engine has a strong reputation for reliability.[4] The General Secretary of Britain's
Licensed Taxi Drivers' Association (LTDA) referred to the TD27 as "one of the greatest engines
ever put in a cab."[15] It was chosen after extensive testing by engineering consultants Ricardo
PLC. The company offset the cost of importing engines from Japan by Nissan agreeing to sell
200 Fairways in Japan every year under the "Big Ben" name.[2] The TD27 continued to be
installed on the succeeding TX1 series.[15]
The TD27 was mainly fitted to a number of Nissan light duty commercial vehicles and was used
as the most common diesel option in Nissan Homy, Caravan, and Urvan vans. Along with the
TD23 and TD25, it was also fitted to the D21 series Datsun Truck (also known as Nissan Pickup,
Navara, etcetera). The turbocharged versions were also fitted to the Nissan Caravan and its
various rebadgings, to the Nissan/Datsun Pickup, the Nissan Terrano SUV (D21 as well as the
succeeding R50), and to the Nissan Terrano II (R20; sold as the Mistral in Japan).

The power range of the regular turbocharged versions (TD27T; built from 1985 until 2007)
range from 100–115 PS (74–85 kW; 99–113 bhp) depending on fitment; when fitted with an
intercooler (TD27Ti) power increases to 125 PS (92 kW; 123 bhp).[16] The most powerful
TD27ETi model, introduced in 1995 and built until 2001, is intercooled, and has an
electronically controlled distributor-type fuel injection pump. The system was called
"electronically controlled fuel injection" by Nissan at the time.[17]
