A basic explanation of common terms used with Ford Escorts.


Twincam: Mk1 Escort Fitted with the Lotus Twincam Engine. Also know as the "Twink"

Mexico: Originally a Mk1 fitted with a 1600cc Kent engine. The Mk2 version was fitted with a 1600cc Pinto engine. The Mexico was produced after Ford Escorts finished 1st, 3rd, 4th and 5th in the 1970 London Mexico Rally. These cars were fitted with 1850cc Kent engines and 5 speed ZF gearboxes. The winning car (FEV1H) was driven by Hannu Mikkola.

RS1600: Mk1 fitted with a 1600cc BDA Engine

RS2000: Mk1 and Mk2 models fitted a 2 litre Pinto engine

RS1800: Mk2 fitted with a 1800cc BDA engine which was enlarged to 2 litres and fitted to the "Works Rally Cars"

Sports Sedan: Not a recognised model but a form of highly modified Race car (include here for clarification only)


Pinto: The common name for the 2 litre motor as fitted to the Cortina, Capri and RS2000 Escort.

Kent: The common name for the over head valve, push rod motors, usually found in either 1100cc, 1300cc or 1600cc form.

Crossflow: See Kent

Twincam: Twin overhead cam engine produced by Lotus. First used in a single seater (Formula 2 ?) race car in the early sixties. The car blitzed the rest of the field until the engine expired.

BDA: Successor to the Twincam. Belt driven twin over head cam 4 valves per cylinder . Originally 1600cc in the mk1 then 1800cc in the Mk2, subsequently enlarged to 2000cc with an alloy block.

Dry Sump: Engine lubrication system where the oil is stored in a container usually mounted in the cars boot as apposed to the standard wet sump system where the oil is stored in the sump beneath the engine. A dry sump system scavenges the oil from the sump and pumps it back to the holding tank from where it is pumped back to the engine. The main benefits are engine does not suffer from oil surge as well as better cooling.


Rail: Refers to the number if rods used by the gear lever to select a gear.

Three rail gearbox: Fitted to the Mk1, Mk2 Cortina and Twincam Escort (see gearboxes for further details)

Single Rail gearbox: Fitted to Mk1 and Mk2 Escorts.(see gearboxes for further details)

Bullet Box: Close ratio version of the Three rail gearbox.(see gearboxes for further details)

Rocket Box: Close ratio version of the single rail gearbox. (see gearboxes for further details)


Diff, Differential: Usually with either a removable diff head (known as the "English" axle) or with the diff head fixed in the axle casing. For competition the Atlas Axle (from a 3 litre Capri) or a narrow Atlas are the preferred options, however the English Axle will handle up to 150 HP, if secured correctly to prevent axle tramp.

LSD: Limited Slip Differential refer The differential page.

Live Rear Axle: Solid or "beam" axle as fitted to all small Fords


Compression struts: Where the front lower control arms (also known as track control arms TCA's) are located by a rod fixed to the TCA and fixed to the chassis rail below the fire wall. These were originally found on the base model cars and vans however some tuners use this method locate the TCA's instead of the more common method of using the sway bar. The compression strut allows for an adjustable front sway bar.

World cup cross member: An Escort cross member with modified engine mounts. developed for the London Mexico "World Cup" rally

Turrets: Modified mounts for rear shock absorbers, changing the shocks a vertical position above the rear axle

5 link Rear axle: This consists of 5 separate rods, 4 of these extend from the axle (2 above and 2 below) forward to mount on the body work approximately where the front of the rear seat rests. The other rod is the Panhard rod which normally extends from the spring mount on one side if the car to the chassis rail on the opposite side. For a five link system to work correctly the rear springs should have the front "eyes" removed with the resulting flat part of the spring should mounted between two rollers.(see 4 link kit)

2 link Rear axle: This consists of 2 separate rods which extend from the above the axle forward to mount on the body work approximately where the front of the rear seat rests. Can also be used with a Panhard rod. (see 4 link kit)

Trailing arms: Name for the rods used in the 5 link and 2 link setup (see above)

Pedal Box: As the name implies this house the pedals, accelerator, brake and clutch. Originally based on the Twincam setup with hydraulic clutch and single brake master cylinder. Most competition pedal boxes have dual brake master cylinders with an adjustable balance bar to alter brake bias, these units may have either a hydraulic or cable clutch.
