We only supply the “Mexico” engine as above.

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 coupled with an increase on BHP, smoothness and gains in petrol consumption, relative to extra power gained.

06 Performance Camshafts

Bearing in mind that any good performance camshaft increases BHP but invariably means a loss in 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.

07 “Mexico” Exchange Camshaft with our Engine

08 “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.

09 SEK 2 Exchange Camshaft Kit with our Engine

10 SEK 2 Exchange Camshaft Kit without our Engine

(Includes modifying your cylinder head)

11 Lightweight Vernier Duplex Valve Timing Kit

12 To ensure infinite valve timing, essential for getting the optimum performance from modified camshafts.

13 Fully set up and timed on our engine.

14 Heavy Duty Valve Spring Set

15 Outright Price

16 With our engine

17 Gas-Flowed Cylinder Heads

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 by between 10 and 15 BHP, ensures a smoother “tickover” and is more economical.

18 Stage 1 : As specifications

19 Stage 2 : As specifications

20 Stage 3 : As specifications

21 We can also do lower compression versions of the above heads, for use on Turbo, Supercharged or Low Compression Engines.

22 Engine Balancing

This ensures a smoother engine, lowers the “tickover” speed and allows it to rev

freely to its optimum. Our engines have a “half balance” (pistons and con rods) included in the price “Bottom End” balance : Crankshaft assembly, refaced flywheel and pressure plate is included in the prices of Stages 2, 3 & 4.

23 “Half Balance” Pistons and rods

24 “Half Balance” Crankshaft, Flywheel and Clutch

25 Heavy Duty Clutches

26 Clutch Release Bearing

27 Heavy Duty Clutch Pressure Plate

28 Heavy Duty Clutch Driven Plate

29 Decking

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.

30 Tuftriding

This is a treatment used in competition cars for strengthening metal.

31 Crankshaft Tuftrided

32 Con Rods (set of four) Tuftrided

33 Uprated Carburettors

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 fittings, to fit your present manifold.

46 Braking Kit

47 Fitted

49 Filter King

50 A fuel pressure regulator which can be used on standard and tuned engines. Designed to save fuel by regulating the fuel feed pressure to the carburettor float

chamber, thereby not allowing the level of the fuel in the float chamber to become higher than its optimum.

51 2000 Overhead Cam for your 1600 X/Flow

52 Simply add this surcharge to whichever stage of tune, in these specifications, you desire.

53 Note : It may be necessary to change distributor, inlet manifold and carburettor, depending on which modified engine you choose.

56 Unleaded Petrol

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 some engine power. In the circumstances we are advising our customers to wait for 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.

57 Advice on Braking & Suspension

As with all our conversions, please ensure braking and suspension are modified to suit extra power.


Do not expect any new engine to perform to the best of its capabilities until it has done at least 4,000 miles. Also the oil and petrol consumption will be greater until the engine has “loosened up”.

Our engines do not include ancillaries, such as clutch disc, clutch plate, bearing, engine mounts, hoses, clips, plugs, points etc. These are decided by you the customer at the time the engine is removed. (It may be that the car has already had some new parts fitted.) So please allow extra for anything required.

58 Suspension

Dependant 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, insulated rubbers, stiffened front springs.

59 Limited Slip Differentials

60 Number Plates

At cost price. With your vehicles registration number – then underneath the number, Specialised Engines Stage 1, 2, 3 or 4 as applicable.

61 “Hotstart” Engine Pre-Heater

Ensures instant warmth to interior, immediate window demisting and improved fuel consumption by a claimed 46% on short journeys. Avoids use of automatic or manual choke and improves safety on wet icy roads by eliminating engine racing whilst on choke. Ensures easy starting and reduces engine wear, extends battery, starter motor and exhaust life. (Up to 50% of engine wear occurs during the first few minutes.)

62 Electronic Ignition

Beware, there are some cheap, poorly made versions on the market. Two noted magazines have done full tests on all makes available. At the time the top two were Mobelec and Luminition. In our opinion there are only slight gains up to 4500 rpm, but after this, mainly due to lack of points bounce, it comes into its own, particularly on tuned units. Against this, any failure means a “normal” garage would not, unlike a normal points set-up, be able to fix it. So we advise you to retain the normal distributor parts and a screwdriver as a “get you home” device.

63 Rolling Road

The July ‘90 issue of Car and Car Conversions made some excellent points on their uses. This bears out what everyone in the tuning business has been saying for years. Basically, ignore the reading, as there are so many variables to consider. Rolling Roads are fine for ‘setting up’ an engine and its ancillaries, provided that the operator is good and that the comparisons are all done on the same ‘road’ and on the same day. Ensure a new engine has done at least 4,000 miles before putting it on a rolling road.

64 Same Day Fitting Service

We set our fitting charges at a very reasonable rate. This is to encourage our customers to take advantage of this very important service. We have very few problems with our engines, except when they are fitted or set-up incorrectly by DIY or outside agencies, which can mean more expense and in convenience for you, as the fitting is then not covered by our GUARANTEE. Whereas if we fit it, the fitting and all parts supplied are completely covered by our guarantee. Upon your arrival at 7.30am the engine is allowed to cool, then removal of the old engine proceeds. You are then shown over your new engine, i.e. the block assembly, showing the pistons, bore and crank sizes etc, then the cylinder head, showing valve type, sizes, springs, guides, seats and gas flowing of chambers and ports as applicable.

Every Engine is completely Hand Built and is the Sole Responsibility of One Engine Builder

By 9.30am your ‘old’ engine has been removed. We then ask you to inspect and decide for yourself if you require replacement of any parts, such as clutch, engine mounts, thermostat, hoses etc. If you are uncertain of what you are looking at, we will show you a new part to compare condition.

65 Radiator Testing

The radiator is sent away (unless new) and is tested under pressure to clear sediment, check rate of flow, repair minor leaks and finally resprayed.

66 DIY Fitting

‘Don’t bite off more than you can chew’ as the Bishop said to the Actress !

‘Have you got the right tool for the job ?’ as the Actress said to the Bishop

Keep everything clean. Use plenty of oil – as Specialised Engines say.

Leave plugs out when first turning the engine over – this will help your ‘old battery and starter motor’ against the new, tight engine. Fill the oil filter with oil, prime it. Set tappets before adjusting time (using a timing light). Read further instructions on the front and back of the engine receipt. PROBLEMS ? STOP ! RING US ! We are here to help you. It is part of the guarantee that you bring the car back to us, for its first service.

Finally – don’t fit it yourself. “We can make a much better job of it and at a reasonable price !” As the Actress said to the Bishop.
