These motors are typically referred to as either the Lima or just the 2.0, 2.3 or 2.5 OHC (Over Head Cam) engines. They started life based on the German design 2.0 EAO sport electric motors that were an initial introduced come this country in the Mercury Capri’s indigenous the early 1970’s. They share nothing v the 2.3 – 2.5 liter HSC electric motors that were offered in the passenger vehicle line native 1984 – 1991.

The 2.3 first debuted in the 1974 Pinto making use of a gradual 2bbl Weber/Holley carburetor and a clues distributor. In 1975 they to be upgraded come a Duraspark ignition system. They stayed unchanged until around 1981 when the intake harbor were adjusted from an oval to a ‘D’ shape (flat floor).


The 2.0/2.3 liter versions the were available in Rangers starting in 1983 supplied a various head having four evenly spaced ring holes of same size. A 2.0 liter 1bbl carbureted variation was offered in rangers from 1983 – 1985, and in 1987 – 1988 through a 2bbl carburetor in some parts of the US, Canada and also Mexico. Digital Fuel Injection (EFI) was included to the engines in 1985. In 1989 the 2.3 was changed to a DIS (Distributorless Ignition System) ignition using a brand-new 8-plug head ( 2-plugs every cylinder). This head had larger same spaced D-shaped input ports and also was offered until the finish of production of the 2.5 in 2001.


The 2.5 liter version was only offered 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 also used higher-flow cylinder heads for far better intake and combustion. The was changed in 2001 through the Mazda-derived Duratec 23.


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

Some the the changes to the motor over the year were:Rear main seal changed from a two item to a one piece design in 1986Roller cams were mounted from 1989 top top in Rangers and also 1991 top top in MustangsCrankshaft main journal sizes to be reduced beginning in 1988CPS (Cam position Sensor) was added beginning in 1995 (1994 in California). Currently Ford adjusted to a 104-pin computer system (it to be a 60-pin) and moved the DIS features into the computer, formerly the DIS system had actually a TFI module together a separate unit placed on the prior of the intake manifold.

Differences between major engine components are together follows:

Blocks:

The 2.0 is an underbored 2.3. With the exemption of the bore, the block are similar to all 2.3’s

1975 – 1988 2.3’s space interchangeable

1989 – 1994 2.3’s room the same as the 1983 – 1988 2.3’s yet have a smaller main journal saddle. The oil pan seal surface ar was changed in 1987 to remove the (4) item seal and also holes were added in the front come bolt on the DIS’s crank cause assembly.

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

Turbo block are the same to the 1983 – 1988 Ranger blocks however have an additional boss v a hole threaded in the passenger side about ½ method back that offers a ar to drain the lubricating oil earlier into the engine from the turbo.

Cranks:

2.0 and early 2.3 cranks space identical.

Late 2.3 cranks have actually smaller main journals.

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

Rods:

2.0 and also 2.3 (including turbo) rods are similar up v at the very least 1994. In truth they still have the original D4 (’74) spreading number top top them.

Pistons:

The 2.0 pistons space unique and don’t interchange.

The 2.3 pistons space all the very same excluding the turbo version which to be 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 comparable to the 2.3’s however have a different wrist pin height.

Heads: 

All 2.0/2.3/2.5 heads will physically bolt in place of each other. They every have similar exhaust port shape and placement. All cams room interchangeable as lengthy as castle are supplied with the appropriate followers. Later model (1995 and newer) roller camer followers can not be quickly swapped top top an older head together the valve stem dimension was diminished in the more recent heads and matching slot in the follower was reduced. Early on 2.0 and 2.3 heads have actually the same little round intake ports spaced same apart. They different from each other in your valve sizes though.

Head Variations:

There are number of variations top top the 2.3 heads though they malfunction into (4) unique types:

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

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

3) van round harbor – 1983 – 1985 Ranger

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