These motors are generally described as either the Lima or ssuggest the 2.0, 2.3 or 2.5 OHC (Over Head Cam) engines. They began life based upon the Gerguy designed 2.0 EAO sport electric motors that were initially presented to this country in the Mercury Capri’s from the early on 1970’s. They share nopoint through the 2.3 – 2.5 liter HSC motors that were offered in the passenger car line from 1984 – 1991.

The 2.3 initially debuted in the 1974 Pinto making use of a progressive 2bbl Weber/Holley carburetor and a points distributor. In 1975 they were upgraded to a Duraspark ignition mechanism. They stayed unadjusted until around 1981 once the intake ports were changed from an oval to a ‘D’ shape (level floor).


The 2.0/2.3 liter versions that were available in Rangers beginning in 1983 offered a various head having actually four evenly spaced round holes of equal dimension. A 2.0 liter 1bbl carbureted variation was readily available in Rangers from 1983 – 1985, and in 1987 – 1988 with a 2bbl carburetor in some parts of the US, Canada and also Mexico. Electronic Fuel Injection (EFI) was included to the engines in 1985. In 1989 the 2.3 was adjusted to a DIS (Distributormuch less Ignition System) ignition making use of a new 8-plug head ( 2-plugs per cylinder). This head had actually bigger evenly spaced D-shaped intake ports and was used till the end of production of the 2.5 in 2001.


The 2.5 liter variation was only offered from 1998 To 2001, as soon as the engine was reinserted by a 2.3 liter DOHC Duratec based engine. The 2.5 was a stroked (by 7 mm) version of the 2.3 OHC Ford Ranger engine. It also provided higher-circulation cylinder heads for much better intake and also combustion. It was reinserted in 2001 by the Mazda-derived Duratec 23.


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

A few of the alters to the motor over the years were:Rear main seal changed from a 2 item to a one piece style in 1986Roller cams were mounted from 1989 on in Rangers and 1991 on in MustangsCrankshaft main journal sizes were decreased beginning in 1988CPS (Cam Position Sensor) was included beginning in 1995 (1994 in California). Right now Ford adjusted to a 104-pin computer system (it was a 60-pin) and also moved the DIS functions right into the computer, formerly the DIS mechanism had a TFI module as a separate unit mounted on the front of the intake manifold.

Differences between major engine components are as follows:

Blocks:

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

1975 – 1988 2.3’s are interchangeable

1989 – 1994 2.3’s are the very same as the 1983 – 1988 2.3’s yet have actually a smaller sized main journal saddle. The oil pan seal surface was readjusted in 1987 to remove the (4) piece seal and holes were included in the front to bolt on the DIS’s crank trigger assembly.

1995 – 2001’s are comparable to the 1989 – 1995’s but a Cam Position Sensor was included 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 similar to the 1983 – 1988 Ranger blocks but have a secondary boss via a hole threaded in the passenger side about ½ way earlier that gives a area to drainpipe the lubricating oil back into the engine from the turbo.

Cranks:

2.0 and at an early stage 2.3 cranks are identical.

Late 2.3 cranks have smaller major journals.

2.5 cranks are identical to 2.3’s other than they have actually a much longer stroke.

Rods:

2.0 and also 2.3 (consisting of turbo) rods are similar up via at least 1994. In reality they still have actually the original D4 (’74) spreading number on them.

Pistons:

The 2.0 pislots are distinctive and don’t interreadjust.

The 2.3 pislots are all the same excluding the turbo versions which were forged. Low compression (8.0:1) in the 1983 – 1888’s and high compression (9.0:1) in the 1979 – 1981’s.

The 2.5 pislots are comparable to the 2.3’s however have actually a various wrist pin elevation.

Heads: 

All 2.0/2.3/2.5 heads will certainly physically bolt in place of each various other. They all have similar exhaust port shape and also placement. All cams are interchangeable as lengthy as they are provided with the appropriate followers. Later design (1995 and also newer) roller cam followers cannot be conveniently swapped onto an older head as the valve stem dimension was lessened in the more recent heads and also corresponding slot in the folreduced was lessened. Early 2.0 and 2.3 heads have actually the very same little round intake ports spaced evenly acomponent. 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 right into (4) distinctive types:

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

2) Passenger vehicle 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 also 1995 – 2001’s have actually different burning chambers and ports. It is assumed that the more recent head is better designed.
