Ford engines:
Engine name Advantages Disadvantages Typical Donor
"Contina" 1600/E (1600cc) strong, (5 bearing crank) and should be cheap if you can find one spares - old - non cross flow/push rod engine based on the "Anglia" 1 litre unit - tunable but otherwise no real advantage in using this engine. It is the basis of the Lotus Cortina engine (see below). MK1, MK2 Cortinas
Lotus twin cam (1600cc) Basically the Cortina engine above but with a Lotus twin cam head. Yes I'd really like one of these but they are now rare, or donor cars are. Plenty of tuning potential. old - spares may be a problem. MK1, MK2 Lotus Cortinas, Twin Cam Escort MK1. Some Lotus cars.
Kent (1100, 1300, 1600) cheap, still available, easily tunable, fits! Push rod engine. MK1, MK2 Escorts, MK2 Cortinas, MK1 Capri
Pinto (1300, 1600, 2000) very available and tunable. SOHC. Plenty of torque on 2000. Tall and heavy. Modifications are needed to get it under a Locost bonnet and still be SVA "friendly". Some of these are available with fuel injection/engine management. MK3/4 Cortinas, MK2/3 Capri, Sierras, RS 2000 Escort Mk2.
CVH (1300, 1600, 1800) tunable, reliable (engine management), available. SOHC (hemi head) Tallish. Used to be some doubt about the strength of the block Later Sierras. Also used in FWD cars. In tuned form in XR2/3i, RS1600i, RSTurbos.
Zetec (2000) DOHC, 16V - modern Ford Expensive parts. Sierra, Mondeos
BDA (1600, 1800) dream on! DOHC. Rare and expensive. MK2 Escorts
Cosworth (2000) ditto. Strong engine. Complicated ancilleries if used in turbo guise. Complete rebuild/different tune strategy if used non turbo. Cosworth Sierras
V6 Cologne injection (2800) strong, cheap, reliable power + torque. big and heavy (all iron), not so well known about as above engines. Push rod valvegear. It may be difficult to find room for the injection and engine management ancilleries. Capri, XR4i and 4x4 Sierras, Granadas
V6 Essex (3000) strong, cheap, reliable power + torque big and heavy (all iron), carburetted, push rod valvegear. Capri, Granadas
V4 interesting, smooth running engine Old - not mainstream. Corsairs, SAAB, Transits.
other engine options:
Rover V8 (3500) Still obtainable, alloy block. It's a V8! Cost a lot to run Rover saloons (SD1) and Land Rovers. Also used by TVR.
BMC A-series Available in many forms. Well understood, tunable. Only up to 1300cc. Push rod, non crossflow engine. Minis (in FWD form), MG Midgets, Minor 1000s, etc, etc.
