950 Fiesta Engine Specifications
All the following engines and parts are suitable for the 957cc Fiesta engine. They will fit in place of any 950 Fiesta car or van engine.
01 Standard Reconditioned Engines
All parts immersed in acid "bath" then chemically "hot" washed and cleaned, with all core and oil gallery plugs removed.
Cylinder Head
Completely reconditioned with new valve springs, stem seals, valves, valve guides, and head surface ground as necessary. All valve seats recut or new inserts fitted as required.
Cylinder Block
Rebored and cross hatch honed. All new core plugs fitted. New matched set of pistons. Mains checked for alignment and ovality. Surface ground where necessary.
Crankshaft - Reground and polished. All new mains and big-end bearings.
Con Rods - Checked for alignment and ovality in big-end housing.
Camshaft - Re-profiled with new or resized cam followers.
Timing Chain and Tensioner - New
Oil Pump - Fully reconditioned or replaced. All new seals and gaskets.
Cylinder Block : Rebored to 0.020" increasing cubic capacity. Each bore cross hatch honed to exact size of each individual piston. Pistons fully balanced.
Oil Pump : New
Crankshaft : Reground to bottom limits available, with matched set of mains and big-end shells.
Con Rods : Crack tested and checked for alignment. Checked for ovality in big-end housing. Fully balanced and lightened.
Camshaft : "Mexico" blueprinted for BHP gains. Or for towing or pulling power, a lower profile camshaft for maximum gains in torque.
03 Stage 2 : As for Stage 1 but including the following :
Cylinder Head : Big valve head, further modified ports, cutting and throating of valve seat areas to accommodate bigger valves.
Cylinder Block : Overbored + 0.040 (1mm) increasing engine size to 1010cc.
Additional Parts for Extra Power and /or Strength
Our modified engines are built for normal Fast Road use, with the emphasis on retaining or increasing torque, but with an increase in BHP, smoothness and gains in petrol consumption, relative to the extra power given.
Bearing in mind that any good camshaft increase BHP but invariably means a loss of torque - the general yardstick is the "higher the lift" the lower the torque. The "Mexico" blueprinted camshaft (included in the price of all stages of tune) gives reasonable gains in BHP with only a slight loss in torque.
06 "Mexico" - Exchange Camshaft with our Engine
07 "Mexico" - Exchange Camshaft without our Engine
For Further Gains in BHP - We recommend the SEK 2. We only supply this camshaft with the Vernier Duplex timing gear kit, machined valve spring seats on cylinder head and heavy duty valve springs.
08 SEK 2 - Exchange Camshaft Kit with our Engine
09 SEK 2 - Exchange Camshaft Kit without our Engine
(includes modifying your cylinder head)
10 Lightweight Vernier Duplex Valve Timing Kit
12 Fully set up and timed on our engine
13 Heavy Duty Valve Spring Set
This process involves machining the rough cast from each of the inlet and exhaust ports, also the combustion chambers (where applicable) to achieve better flow to each cylinder. Increases power between 10 and 15 BHP.
It ensures a smoother "tickover" and is more economical.
17 Stage 1 : As specifications
18 Stage 2 : As specifications
19 Stage 3 : As specifications
22 Half Balance : Pistons and Con Rods
23 Half Balance : Crankshaft, Flywheel, Clutch
26 Heavy Duty Clutch Pressure Plate
27 Heavy Duty Clutch Driven Plate
Removing metal from piston crown and/or block to equalise piston heights to achieve absolute balanced compressions. Included in some stages of tune (see specifications). Included in Stage 4 versions.
29 Tuftriding: This is a treatment used in competition for strengthening metal.
31 Con Rods Tuftrided (set of four)
Specially jetted and choked to fit whichever engine size or state of tune required. New modified Weber carburettor with full manual choke conversion and all necessary linkages and fitting, to fit your present manifold.
35+36 Gas Flowed Inlet Manifold
Flowing of the inlet manifold improves efficiency
42 Performance Exhaust Manifolds + Systems, which give useful gains in power. Price depending on application
Includes new 1100 distributor. Simply add this surcharge to whichever stage of tune, in these specifications, you desire. 51a 1300cc for your 950 X/Flow Modification includes replacement Weber carburettor (twin choke), K& N Filter, Inlet Manifold, 4 - branch exhaust manifold, 1300 Sport exhaust system (modified), sports distributor, gearbox torque, mounting bracket and bar, modified flywheel and heavier duty clutch. Other modifications as necessary. 51b 1600cc for your 950 X/Flow Additions necessary, as for 1300. On some early Fiestas it may be necessary to change type of starter motor, also radiator expansion tank, if not already fitted ; neither allowed for in above prices. It may be necessary to change fan housing and/or fan assembly on some MK1 Fiestas when fitting 1600 for 957. But all MK2 Fiestas onwards are OK. Although we offer converted heads, we consider this a last resort. It involves fitting valve seat inserts which can crack, or worse, drop into the bore, causing severe damage. This usually happens through overheating or if the engine is stressed. It is advisable to retard the ignition by some 3 to 4 degrees, which in turn means losing engine power. In the circumstances we are advising our customers to wait to L.R.P. (Lead Replacement Petrol) to come onto the market. SHELL have stated that they will be replacing their leaded pumps with this, come changeover. They have already done so in most European countries which have banned leaded petrol. They claim that long term tests have shown that it is a safe and suitable replacement. Advice on Braking and Suspension Our engines do not include ancillaries, such as clutch disc, clutch plate, bearing, engine mounts, hoses, clips, plugs, points etc. Theses are decided by you the customer at the time the engine is removed. (It may be the car has already had some new parts fitted.) So please allow extra for anything required. Dependent on type of vehicle, but gas filled shock absorbers or adjustable type shock absorbers, anti-dive kits, single leaf rear springs, negative camber cross members, toughened insulation rubbers, stiffened front springs etc. At cost price. With your vehicles registration number - then underneath, Specialised Engines Stage 1, 2, 3 or 4 as applicable.
