1985 engine

[tsr48]

I need a 1985 engine complete for a 2wd pickup. tsr48@sbcglobal.net

ummmm ok. What size? I am assuming it is a Nissan since you posted here, but if I remember correctly they offered a few choices.... I am assuming for a 2wd you need a 4 cylinder... but are there different sizes? options? Like do you have A/C? Complete 1985 engine is extremely vague.... might not get a lot of responses.

Yes it is a 4 cylinder, I believe the z24, with carb, 2wd.

[junior3382]

Where are you located... and how far are you willing to travel for the motor?

[tsr48]

southeast Kansas
Haven't really thought about it yet, it probably depends on how good the motor is and the mileage on it.

[junior3382]

Thats a little far.... my buddy has one for sale, but he is way up north. It would cost less to go to a local junk yard. Thought it would have worked. Sorry bud. Wish I could have helped more.

I believe it's an L24. Basically the same as a Datsun Z motor, but 4 cylinders instead of 6.

get into the phone book of the bigger cities and look for motor refurbishers

1985 Nissan truck 4 cylinder engine is the Z24 with 8 spark plugs. L24 4 cylinder engine with 4 spark plugs was last used in Nissan minitrucks in 1980.

Nissan Z24 engine is one of the very best engines available in minitrucks. One of mine has over 350,000 miles on it and the other one is nearly 260,000 miles. Neither engine has ever been opened up. About the only weak point in them is the fan clutch. When it fails you have to replace the water pump, since the fan clutch is non-separable from the water pump. Nissan used the Z24 from 1982 (or 1983, I'm not exactly sure) thru 1990. with some possibly being used in 1991.

The 1981 engine was a Z22, standing for 2.2 liters. In 1991 they switched over to the KA24 (4 spark plugs) engine, which has a better torque curve than the Z24, but a serious weakness in the timing chain becoming loose and destroying the front cover and sometimes (i heard) wearing a whole in the front of the engine block.

The Z24 engine was carburated from 1981 thru 1986 (early) and fuel injected in the hard body truck (1986-1/2 thru 1990). I know the 1984 Z24 engine used an electronic feedback carburetor (requiring a "computer"), and I think the 1985 and early 1986 also used a feedback carb and computer. Every year from 1981 thru early 1986 used a different carburetor, so swapping during those years is problematical, because of the emission laws concerning "required" equipment. The basic Z24 block was the same from 1983 thru 1991, so if you work hard enough you could swap the carbs & intake manifolds (and exhaust manifolds because of the **** emissions laws) or put the injection systems onto the earlier blocks. Anything is possible but it is difficult to swap between the three engine families, again mostly because of the emissions laws.

All of the Nissan 4 cylinder truck engines are in-line engines; there were no V4s. The Nissan V6 truck engine provided only a little more power, at both considerability more maintenance cost and less durability.

The 4 cylinder engines were available in Pathfinders, but were less economical because of the greater weight of the Pathfinder. From what I have seen, they didn't last as long as in the trucks, probably because of the increased load of the Pathfinder chassis.
