Hi all,

I'm new to this forum because I'm new to Datsun. In just 1 hour this truck is being delivered to my house. Original paint 168K miles, 180psi compression all around. I'm pretty picky when it comes to buying a vehicle and this thing looks like a cream puff. It will become my work vehicle as I'm a carpenter so I'll have to be careful to keep it in good shape like the previous owners.

Couple questions for you vets:How do I find what size of stereo I can put in?What do people typically get for gas mileage? Mine is 2wd.

cheers,Justin

welcome!

not 100% sure what you mileage will be cause you're running a different engine than i am... but 20 ish sounds about right... as far as the stereo, you can make just about anything work... before i started racing mine i had custom 6x9 speakers in place of the stock speakers down by the kick panels and 2 12" subs firing down behind the passenger seat with the amp behind my seat...

truck looks good!!!

thanks. yeah if I get 20 mpg I'd be happy.

I think you're right about the stereo. I'm just concerned about it being so easy to get stolen. It's going to be a work truck (though not treated like one).

well, wiki says"

In 1979.5 and 1980, models were powered by Datsun's 2.0L carbureted L20B engine, but soon after switched to the Nissan Z engine line, In the Middle East it was powered by Datsun's 1.8L carbureted L18 engine.

The 1981-1982 models used the Z22 carbureted 2.2L engine and an optional SD22 Diesel.

In mid-1983 Nissan introduced the Z24 2.4 Liter 8 spark plugs 4 cylinder motor, it produces 103 hp (77 kW), Z20 2.0 Liter and the SD25 Diesel; this happened at the same time that the 720 series was marketed as a Nissan (the Datsun name, which had disappeared entirely after 1984, was now only seen below the Nissan name on the left corner of the tailgate).

In the American market the diesel engine was only available in the 2WD 720 (from 1982 to 1985). The Z24 was upgraded to Z24i fuel-injection (option) for the 1986 models. Additionally, some overseas markets received versions with the 1.5L J15, 1.6L J16 or 1.8L L18 carbureted engines. The 720 Series was never available with any of the Z22E or Z20E multi-port fuel injected engines. These engines are, however, easy to adapt and integrate into the chassis and can be found with the genuine appearance of being original equipment."

The L20B was a 1952cc engine produced from 1975 through 1985. It produces 100 hp (75 kW) in 1981 form with 112 lb·ft (152 N·m) of torque as installed in the 200 SX. The engine originally used a carburetor but switched to fuel injection (and round instead of square exhaust ports) in 1977. Carburetors were used in trucks until 1980 when the L20B was replaced with the Nissan Z engine series.
