Differences between major engine parts are as follows:
Blocks:
The 2.0 is an underbored 2.3. With the exception of the bore, the blocks are identical to all 2.3s
1975 - 1988 2.3s are interchangeable
1989 - 1994 2.3's are the same as the 1983 - 1988 2.3s but have a smaller main journal saddle. The oil pan seal surface was changed in 1987 to eliminate the (4) piece seal and holes were added in the front to bolt on the DISs crank trigger assembly.
1995 - 2001's are similar to the 1989 - 1995s but a Cam Position Sensor was added behind the aux sprocket. The hole for the distributor was eliminated and the oil pump was moved in place of the aux. shaft itself.
Turbo blocks are identical to the 1983 - 1988 Ranger blocks but have an additional boss with a hole threaded in the passenger side about ½ way back that provides a place to drain the lubricating oil back into the engine from the turbo.
Cranks:
2.0 and early 2.3 cranks are identical.
Late 2.3 cranks have smaller main journals.
2.5 cranks are identical to 2.3s except they have a longer stroke.
Rods:
2.0 and 2.3 (including turbo) rods are identical up through at least 1994. In fact they still have the original D4 (74) casting number on them.
Pistons:
The 2.0 pistons are unique and dont interchange.
The 2.3 pistons are all the same excluding the turbo versions which were forged. Low compression (8.0:1) in the 1983 - 1888s and high compression (9.0:1) in the 1979 - 1981s.
The 2.5 pistons are similar to the 2.3s but have a different wrist pin height.
Heads:
All 2.0/2.3/2.5 heads will physically bolt in place of each other. They all have similar exhaust port shape and placement. All cams are interchangeable as long as they are used with the proper followers. Later model (1995 and newer) roller cam followers cannot be easily swapped onto an older head as the valve stem size was reduced in the newer heads and matching slot in the follower was reduced. Early 2.0 and 2.3 heads have the same small round intake ports spaced evenly apart. They differ from each other in their valve sizes though.
Head Variations:
There are several variations on the 2.3 heads though they break down into (4) distinct types:
1) Passenger car oval port heads - 1974 - 1980 Mustang, Pinto, Fairmont, Bobcat, etc.
2) Passenger car D-port head - 1981 - 1995? T-bird, Mustang, Etc.
3) Truck round port - 1983 - 1985 Ranger
4) Truck D-port - 1989 - 2001 Ranger. The 1989 - 1994's and 1995 - 2001's have different combustion chambers and ports. It is thought that the newer head is better designed.

Modifications:
Air Muffler:
Start off with an improved air intake to let the engine breath better. Below left you can see the Air Muffler and the baffle. The air muffler (on the left) goes between the air cleaner and the throttle body. The baffle to the right of it comes off the front of the air cleaner inside the body of your Ranger above the wheel well. As you can see in the picture below right, the air muffler was replaced with a piece of stainless but you can use PVC pipe. This will allow more air flow into your motor, increase HP, and make your motor a little bit louder. Your air cleaner is in two (2) parts; air cleaner canister, and mass air flow sensor. Open your air cleaner and remove the air filter, then unbolt the can in which the filter was in, when you pull the can off, the baffle will be attached to it. Remove the baffle, and reinstall the air cleaner. This will add more air flow, HP, and sound to your Ranger.
K&N offers an AirCharger replacement air intake for 1995+ 2.3 Rangers
Port your upper and lower intake. The intakes don't line up diameter to diameter. Porting opens this up and allows better flow. Knife edge the intake side of the throttle body to remove the front lip. You can use a Dremel tool to grind, sand and buff this area to obtain a smooth airflow in to the engine. You can also mill down the butterfly to blend in to the shaft for a smoother air flow.

If our looking for more low end torque, upgrade your rear gears to a lower (numerically higher) ratio.
Flex-A-Lite makes a replacement fan for the Ranger so you can replace your clutch driven fan to reduce drag on the engine.
'Odysseus' - I recently had some trouble with the truck bucking sporadically, or when it rained. The EGR valve was sticking. I removed the hose that comes out from the fuel injector to the valve and plugged it with an ink pen. Cleared it right up. I actually noticed it has a little more power too. Just trying to save you guys some trouble.
