The D21 Hardbody started production in Late 1986 and was introduced as an 87Model. There were only 2 engine options for the Hardbody platform.
The 2.4L-4Cyl and the 3.0 V6.
I think the 2.4L was rated somewhere around 120 HP Stock (don't quote me on that though)
The early 3.0L was rated for around 150 HP and about 170 ft/pds of torque.When the 90's came the engine got Fuel Injection and got upgraded to about 160 HP and 180 ft/pds.The last year of the Hardbody was in 1999 (EDIT: My bad I meant to type 1997...not sure where my head was late last night) when the Frontier made it's debut with the newer engines. A more powerful 2.4 and a bigger V6, the 3.3liter which was already being used in the Pathfinders of the late 90's. The Pathy was of course bumped into the 3.5L range with wellover 220HP and torque to match.
The Hardbody is a good work truck. But it is not the ideal platform for pulling a car over long distances. They simply don't have the towing power needed to climb hills, even gradual ones on the highway. Short jaunts would probably be ok though.
The hardbody used one maybe two different model rear diffs. The most common is called the 233B and it had a few different gear ratios. These vary depending on the engine size, year of manufacture, 2WD, or 4WD, automatic or standard transmission. The serial number can be decoded and it should tell you what it has. At least that's what my local Nissan Parts guru tells me.
There are a few people here talking about dropping a 240 engine into a Hardbody because it has superior power and can be beefed up quite abit. Check out some of the more recent strings on this Trucks Forum and perhaps you can gleen something more from their info.
