These electric motors are commonly referred to together either the Lima or merely the 2.0, 2.3 or 2.5 OHC (Over Head Cam) engines. They started life based on the German draft 2.0 EAO sport electric motors that were an initial introduced come this nation in the Mercury Capri’s native the early 1970’s. They share nothing through the 2.3 – 2.5 liter HSC motors that were offered in the passenger auto line from 1984 – 1991.

The 2.3 first debuted in the 1974 Pinto using a gradual 2bbl Weber/Holley carburetor and also a points distributor. In 1975 they were upgraded come a Duraspark ignition system. They continued to be unchanged until about 1981 as soon as the intake ports were readjusted from an oval to a ‘D’ form (flat floor).


The 2.0/2.3 liter versions the were readily available in Rangers starting in 1983 used a various head having 4 evenly spaced round holes of equal size. A 2.0 liter 1bbl carbureted version was readily available in rangers from 1983 – 1985, and in 1987 – 1988 through a 2bbl carburetor in some components of the US, Canada and also Mexico. Digital Fuel Injection (EFI) was included to the engines in 1985. In 1989 the 2.3 was adjusted to a DIS (Distributorless Ignition System) ignition utilizing a brand-new 8-plug head ( 2-plugs per cylinder). This head had larger evenly spaced D-shaped input ports and also was offered until the end of manufacturing of the 2.5 in 2001.


The 2.5 liter variation was only readily available from 1998 come 2001, once the engine was changed by a 2.3 liter DOHC Duratec based engine. The 2.5 was a stroked (by 7 mm) variation of the 2.3 OHC Ford Ranger engine. It additionally used higher-flow cylinder heads for much better intake and also combustion. That was replaced in 2001 by the Mazda-derived Duratec 23.


In 1979 – 1981 a high compression attract thru carbureted turbo version of the 2.3 to be offered. In 1983 – 1988 a reduced compression EFI turbo variation was offered in T-birds, Cougars, Mustang SVOs and Merkur XR4Ti’s (through 1989).

Some of the alters to the motor over the years were:Rear key seal adjusted from a two item to a one piece style in 1986Roller cams were set up from 1989 ~ above in Rangers and also 1991 on in MustangsCrankshaft key journal sizes to be reduced starting in 1988CPS (Cam position Sensor) was added starting in 1995 (1994 in California). Currently Ford readjusted to a 104-pin computer (it to be a 60-pin) and also moved the DIS attributes into the computer, previously the DIS system had a TFI module as a different unit placed on the front of the intake manifold.

Differences between major engine components are together follows:

Blocks:

The 2.0 is one underbored 2.3. Through the exemption of the bore, the block are the same to every 2.3’s

1975 – 1988 2.3’s room interchangeable

1989 – 1994 2.3’s are the exact same as the 1983 – 1988 2.3’s yet have a smaller main journal saddle. The oil pan seal surface was readjusted in 1987 to get rid of the (4) piece seal and holes were included in the front to bolt top top the DIS’s crank create assembly.

1995 – 2001’s are comparable to the 1989 – 1995’s yet a video camer Position Sensor was included behind the aux sprocket. The hole for the distributor to be eliminated and also the oil pump was moved in location of the aux. Tower itself.

Turbo blocks are the same to the 1983 – 1988 Ranger blocks but have second boss through a hole threaded in the passenger side around ½ method back that provides a ar to drain the lubricating oil back into the engine from the turbo.

Cranks:

2.0 and also early 2.3 cranks space identical.

Late 2.3 cranks have smaller main journals.

2.5 cranks are identical to 2.3’s except they have a longer stroke.

Rods:

2.0 and also 2.3 (including turbo) rods are similar up with at least 1994. In fact they still have actually the initial D4 (’74) casting number ~ above them.

Pistons:

The 2.0 pistons space unique and don’t interchange.

The 2.3 pistons room all the exact same excluding the turbo execution which were forged. Short compression (8.0:1) in the 1983 – 1888’s and also high compression (9.0:1) in the 1979 – 1981’s.

The 2.5 pistons are similar to the 2.3’s yet have a different wrist pin height.

Heads: 

All 2.0/2.3/2.5 heads will physically bolt in place of every other. They all have comparable exhaust port shape and also placement. All cams space interchangeable as lengthy as they are supplied with the ideal followers. Later model (1995 and also newer) roller video camer followers cannot be conveniently swapped onto an larger head together the valve stem size was decreased in the newer heads and also matching slot in the follower to be reduced. Beforehand 2.0 and 2.3 heads have actually the same tiny round intake harbor spaced evenly apart. They different from each other in their valve sizes though.

Head Variations:

There are several variations top top the 2.3 top though they failure into (4) distinct types:

1) Passenger vehicle oval port heads – 1974 – 1980 Mustang, Pinto, Fairmont, Bobcat, etc.

2) Passenger car D-port head – 1981 – 1995? T-bird, Mustang, Etc.

See more: How Many Yards Is 60 Inches To Yards, Inches To Yards Conversion (In To Yd)

3) van round harbor – 1983 – 1985 Ranger

4) truck D-port – 1989 – 2001 Ranger. The 1989 – 1994’s and 1995 – 2001’s have actually different burning chambers and ports. That is assumed that the more recent head is far better designed.
